Trypillia and Greece Neolithic outliers: the smoking gun of Proto-Anatolian migrations?

neolithic-migrations-khvalynsk-novodanilovka-anatolian

(Continued from the post Corded Ware culture origins: The Final Frontier).

Looking at the PCA of Wang et al. (2018), I realized that Sredni Stog / Corded Ware peoples seem to lie somewhere between:

  • the eastern steppe (i.e. Khvalynsk-Yamna); and
  • Lower Danube and Balkan cultures affected by Anatolian- and steppe-related (i.e. Khvalynsk-Novodanilovka) migrations.

This multiethnic interaction of the western steppe fits therefore the complex archaeological description of events in the North Pontic, Lower Danube, and Dnieper-Dniester regions. Here are some interesting samples related to those long-lasting contacts:

1. I3719 (mtDNA H1, Y-DNA I2a2a) Ukraine Neolithic sample from Dereivka ca. 4949–4799 BC, described in Mathieson et al. (2018) as of “entirely northwestern-Anatolian-Neolithic-related ancestry”.

2. ANI163 from Varna I ca. 4711–4550 BC (mtDNA H7a1), and I2181 from Balkans Chalcolithic (Smyadovo, in Bulgaria) ca. 4500 BC (mtDNA HV15, Y-DNA R) show the first steppe ancestry in regions known to be affected by the expansion of Suvorovo chiefs.

3. The Yamna Bulgaria outlier (Y-DNA I2a2a1b1b), 3012-2900 calBCE, shows apparently an admixture with cultures of that region (but 1,500 years later).

See the original file here.

Trypillia and Corded Ware

4. There is one ‘Trypillia outlier’ among five samples from the Verteba cave in Wang et al. (2018): I1927 (Y-DNA G2a2b2a1a1b1a1a1, mtDNA H1b), ca. 3619-2936 BC, a sample published previously in Nikitin et al. (2017) and Mathieson et al. (2017). We were very quick to dismiss Trypillia (three samples of haplogroup G2a, one sample E) and GAC as a source of Corded Ware admixture, but archaeology clearly shows important population movements at the end of the fourth millennium between late Trypillia groups, GAC, and post-Sredni Stog populations, and genetics is showing that in both cultures, too.

I am not a fan of the ‘lack of samples’ argument, but (similar to Old Hittite samples related to all Anatolian speakers) one site is not enough to describe a culture that spanned millennia and many different early and late groups. One among five Trypillian samples (from a single site), showing a late date (ca. 3228 BC) compared to the other samples (ca. 3700 BC), and quite close to the only three Ukraine Eneolithic samples we have may mean much more than what we may a priori think, i.e. some simplistic unidirectional punctual ‘intrusion’ of steppe ancestry, and instead hint at the known close contacts of late Trypillian groups and North Pontic cultures, including also the Caucasus.

NOTE. The big difference in PCA among GAC-like Hungary LCA – EBA samples (see above two star symbols close to Ukraine Neolithic outlier in the PCA, in contrast with the other three at the bottom) may also be significant, although we don’t have any data about their culture, sites, or the relationship between them.

Greece Neolithic outlier: Proto-Anatolians?

5. Especially interesting is I6423, one of the Greece Neolithic samples referred to in Wang et al. (2018), which is obviously an outlier among the three used in the paper. It does not seem to correspond to any of the ancient DNA samples published to date; it is not in Hofmanova et al. (2016), in Lazaridis et al. (2017), or in Mathieson et al. (2018).

Since the Neolithic in Greece could mean any period from ca. 6500 BC to ca. 3200 BC, I guess we are talking here about some migration related to the expansion of Khvalynsk-Novodanilovka chieftains after ca. 4500 BC, because it appears on the PCA precisely on the same spot as Varna and Smyadovo outliers, and its ADMIXTURE shows similar components

Image modified from Wang et al. (2018). “ADMIXTURE results of relevant prehistoric individuals mentioned in the text (filled symbols)”. ‘Outlier’ samples referred to in this post have been marked in red. See the original file here.

So, this may be the smoking gun of Proto-Anatolian (or maybe early Common Anatolian) expansion with steppe migrants up to the border of Western Anatolia, and we may be able to get rid of those unfounded doubts about Anatolian origins once and for all…

NOTE. Also interesting seems another Greece Neolithic sample, I6420, in ADMIXTURE, although its position in the PCA (near Minoans and Mycenaeans) does not necessarily point to potential steppe influence, but rather to the extra ‘eastern (Caucasus/Iran-related) ancestry’ contribution found in Minoans and in Mycenaeans (and Anatolia Chalcolithic) compared to previous samples of the region. The third Greece Nelithic sample, I5427 (mtDNA K1a24), from Diros, Alepotrypa Cave, is dated 6005-5879 BC (mean 5892 BC), and appeared first in Mathieson et al. (2018).

If this Greece Neolithic sample is not related to Yamna migrations – and its use for statistical analysis of Caucasus samples from Wang et al. (2018) suggests that it is not – , it may have important consequences:

If it is located near the Western Anatolian coast – especially near Troy – there won’t be much to add about the potential site of entry of Common Anatolian languages into Anatolia… I have read some comments about how ‘impossible’ it was for steppe migrants and their language to ‘invade’ the more advanced cultures of Anatolia from the west, but it seems as ‘impossible’ as it was for Barbarians to invade the Roman Empire and impose their language as elites in certain regions. (And yes, we have at least one important weak political period among Middle Eastern cultures in the early 3rd millennium BC, similar to the period of the Fall of the Western Roman Empire).

indo-european-anatolian-uralic-migrations
Most likely Proto-Anatolian expansion in the North Pontic and Balkan area with Khvalynsk-Novodanilovka chieftains, including ADMIXTURE data from Wang et al. (2018).

If it is located somewhere more ‘central’ in the Greek Peninsula, then it could also be used to support the Anatolian nature of the controversial Pre-Greek (‘Pelasgian’) substrate. While we know that Greek (at least since Mycenaean) shows a strong Pre-Greek cultural and linguistic heritage (also reflected in its genetic continuity), the nature of that language is usually believed to be non-Indo-European, and Anatolian contacts are rather few and coincident with the Mycenaean period. I don’t think this sample can tell much about the Pre-Greek language, though, because – if it is really Neolithic, and comparing it with later Minoan and Mycenaean samples – it seems a clear outlier.

suvorovo-novodanilovka-expansion-europe
Heyd (2016): The Southeast European distribution of graves of the Suvorovo-Novodanilovka group and such unequipped ones mentioned in the text which can be attributed by burial custom and stratigraphic position in the barrow, plus zoomorphic and abstract animal head sceptres as well as specific maceheads with knobs as from Decea Maresului (mid-5th millennium until around 4000 BC). The site in the south-west Balkans is Suvodol-Šuplevec, Northern Macedonia (FYROM).

If it is, however, related to later Yamna migrations after ca. 3000 BC (and, like the ‘Ukraine Eneolithic’ sample that is likely from Catacomb, it is classified as Neolithic just because it cannot be attributed to precise Helladic periods), then we may be in front of the first obvious Yamna migrants in Greece. If that is the case (which I doubt), the sample wouldn’t be so informative for PIE dialectal expansions, because by now it is evident that we will find steppe ancestry and R1b-Z2103 subclades accompanying Yamna migrants in the southern Balkans, and probably well into Mycenaean Greece.

NOTE. Whatever the case, I am sure that for those fond of absurd autochthonous continuity theories, as well as for anti-steppe conspirationists, this sample will be just another good way of arguing for anything, ranging from a rejection of the Middle PIE – Late PIE division, to a support for some mythic ancient autochtonous Proto-Graeco-Anatolian group, or maybe some ancient Graeco–Indo-Slavonic split, or whatever new dialectal stage one can invent to support the own genealogical fantasies…

So, if it actually is a Neolithic sample, let’s hope that it shows a clear R1b-M269 (xL23 or early L23) subclade distinct from those (likely Z2103) expanded later with Late PIE-speaking Yamna (and probably to be found among Mycenaeans), so that there can be no more place for ethnic fantasies.

Corded Ware culture origins: The Final Frontier

corded-ware-yamna-bell-beaker

As you can imagine from my latest posts (on kurgan origins and on Sredni Stog), I am right now in the middle of a revision of the Corded Ware culture for my Indo-European demic diffusion model, to see if I can add something new to the draft. And, as you can see, even with ancient DNA on the table, the precise origin of the Corded Ware migrants – in spite of the imaginative efforts of the Copenhagen group to control the narrative – are still unknown.

Corded Ware origins

The main objects of study in Corded Ware origins are necessarily the region where the oldest Corded Ware vessels appeared, Lesser Poland, as well as the adjacent (traditionally considered Proto-Corded Ware regions) Volhynia, Podolia, and upper Dniester river basin. These are some relevant points, continuing where I left the Eneolithic steppe developments (following Szmyt 1999, Rassamakin 1999, Kadrow 2008, Furholt 2014):

gac-trypillia-yamna-usatovo
Kadrow (2008). Cultural interactions around Carpathians at the beginnings of the 3rd millennium BC: 1 – Globular Amphora culture; 2 – Sofievka group of Trypillia culture; 3 – Funnel Beaker culture; 4 – Baden culture; 5 – Kostolac culture; 6 – Coţofeni culture; 7 – Cernavoda II culture; 8 – Yamnaya culture and Usatovo group of Trypillia culture (apud Kadrow, 2001).
  • More frequent contacts were seen ca. 3500-3000 BC, with an interaction showing multidirectional migrations of larger human groups in the centuries around 3000 BC, involving a significant part of the population of central-east Europe.
  • The easternmost area of the Funnel Beaker culture had become more Baden-like with the expansion of the Baden culture in its western area ca. 3300-2900 BC (with findings up to 2600 BC), and these younger groups with Baden features moved increasingly into the western part of Volhynia.
  • The influence of the neighbouring Trypillian culture is seen in the eastern parts of Volhynia, from ca. 3000 BC, either from a younger phase CII (cf. Troyaniv, Koshilivtsy, Brînzeni, Zhvaniets, or Vychvatintsy) or later groups (cf. Gorodsk, Kasperivtsy, Sofievka, Horodiştea-Folteşti, Usatovo).
  • In the forest-steppe zone, herding and hunting activities intensified, while agricultural traditions were preserved, as shown by the Sofievka, Kasperivtsy, and Gorodsk groups. From the end of the 4th millennium BC mobile parts of the late Trypillian populations moved to the steppe zone, absorbing more and more steppe elements; among others, cord ornamentation (in Vykhvatintsy, Troyaniv, and Gorodsk groups), pottery forms (Vykhvatintsy, which served as prototype for the Thuringian Apmphorae, dispersed along the Dniester river, too), flat burials with bodies in contracted position on the left or right side (Vykhvatintsy, reminding of Polgár culture different male-female position, and later Corded Ware burials, and also Lower Mikhailovka, under a mound without stone constructions). At the end of the Trypillia culture, its agricultural system collapsed completely.
gac-trypillia-usatovo-corded-ware
Globular Amphorae culture „exodus” to the Danube Delta: a – Globular Amphorae culture; b – GAC (1), Gorodsk (2), Vykhvatintsy (3) and Usatovo (4) groups of Trypillia culture; c – Coţofeni culture; d – northern border of the late phase of Baden culture;red arrows – direction of Globular Amphora culture expansion; blue arrow – direction of „reflux” of Globular Amphora culture (apud Włodarczak, 2008, with changes).
  • Slash and burn techniques of agriculture – especially those practiced by Trypillian and Funnel Beaker populations – must have intensified effects of natural growth of humidity (ca. 3400-2400), increasing fluvial activities in west Ukrainian river valleys, and increasing deforestation processes, which favoured pastoralism and nomadisation of the settlement system, and a consequent change of the social structure
  • At the same time, Yamna communities expanded along the lower and central Danube to the west, while the populations of the late phase of the Baden culture took the opposite direction and reached as far as Kiev in the north-east, contributing to the culture of the Sofievka group.
  • Globular Amphora communities migrated from the north-west, from eastern Poland, towards the Danube Delta and as far as the Dnieper in the east, destroying the primary structures of the communities in the supposed cradle territories of the Corded Ware culture. These communities found refuge and conditions for further development in south-eastern margin zone of the Funnel Beaker culture territories, penetrating at first the upper parts of the loess uplands like typical Funnel Beaker sites, but on the margins of their range, and also on areas avoided by Funnel Beaker settlement agglomerations. They brought with them the so-called Thuringian amphora up to Lesser Poland, borrowed from the late Trypillian Usatovo group. This resulted in the Złota culture, which eventually gave rise to the A-Amphorae.

In the end, we are left with this information about the oldest CWC (Furholt 2014):

  • The earliest radiocarbon-dated groups associated with the Corded Ware culture come from new single graves from Jutland in Denmark and Northern Germany, ca. 2900 BC. This Early Single Grave culture is associated with the appearance of individual graves (some time after the decline of the megalithic constructions), composed of a small round barrow and a new gender-differentiated burial practice emphasising male individuals orientated west-east (with regional exceptions), combined with the internment with new local battle-axe types (A-Axe). However, there is no single type of burial or burial custom in Corded Ware:
    • In southern Sweden the prevailing orientation is north-east – south-west, and south-north, contrary to the supposed rule male individuals are regularly deposited on their left and females on their right side.
    • In the Danish Isles and north-eastern Germany, the Final Neolithic / Single Grave Period is characterized by a majority of megalithic graves, with only some single graves from typical barrows. In south Germany, west-east and collective burials prevail, while in Switzerland no graves are found.
    • In Kujawia (south-eastern Poland), Hesse (Germany), or the Baltic, west-east orientation and gender differentiation cannot be proven statistically.
corded-ware-regions-main
Furholt (2014). Map of the Corded Ware regions of central Europe. The dark shading indicates those regions where Corded Ware burial rituals are present regularly
  • The oldest Corded Ware vessels (the A-Amphorae, which define the A-Horizon of the CWC) come probably from the Złota (or a related) group in Lesser Poland, where a mixed archaeological culture connecting Funnel Beaker, Baden, Globular Amphorae and Corded Ware appears ca. 2900-2600 BC. No cultural (typological) break is seen between earlier Globular Amphorae and the first Corded Ware Amphorae, but rather a continuum of traits and characteristics among the recovered vessels. This strengthens the connection of Corded Ware with Globular Amphorae peoples. The A-horizon expanded thus probably from Lesser Poland ca. 2800-2600, as seen in local contexts.
  • And of course we have a third way of defining Corded Ware individuals, which is the presence of herding, and thus a transition from hunter-gatherers to agropastoralists. This is how some Baltic Late Neolithic individuals with no archaeological data have been classified as members of the Corded Ware culture: Even though no cultural remains were extracted with the two ‘outlier’ individuals, their haplogroup and ancestry point to a direct origin in or around the steppe and forest-steppe region (yes, that risks circular reasoning).
globular-amphorae-corded-ware-zlota-amphorae
Correspondence analysis of amphorae from the Złota-graveyards reveals that there is no typological break between Globular Amphorae and Corded Ware Amphorae, including ‘Strichbündelamphorae’ (after Furholt 2008)

Corded Ware peoples in genetics

So, no clear origin of Corded Ware migrants, a lot of data pointing to intense migrations and interaction among GAC, Trypillia and the western steppe population (remember Kristiansen’s ‘long-lasting GAC-CWC connection’, now ignored to favour their Yamnaya admixture™ concept), and also three ways of defining Corded Ware culture…

Maybe genetics can help:

Ukraine Neolithic cultures – mainly from Dereivka – show haplogroups R1b-V88, R1a1, and R1b-L754 (xP297, xM269), which is similar to the haplogroup distribution found in Ukraine Mesolithic, but apparently with an expanding group marked by haplogroup I2a2a1b1 (possibly I2a2a1b1b).

The first thing that stands out about Ukraine Eneolithic samples is that only two of them can be said to be really Ukraine Eneolithic (i.e. from “Sredni Stog”-related groups):

  • I5876 (Y-DNA R1a-Z93(Y3+), mtDNA U5a2a), from Alexandria, 4045-3974 calBCE (5215±20BP, PSUAMS-2832)
  • I4110 (mtDN AJ2b1), from Dereivka, 3634-3377 calBCE (4725±25 BP, UCIAMS-186349), J2b1

The other two samples are quite late, and in fact one of them is clearly too late (maybe from the Catacomb culture):

  • I5882 (mtDNA U5a2a), from Dereivka, 3264-2929 calBCE (4420±20BP, PSUAMS-2826)
  • I3499 (Y-DNA R1b-Z2103, mtDNA T2e), from Dereivka, 2890-2696 calBCE (4195±20BP, PSUAMS-2828)

Corded Ware samples from Mittnik et al. (2018) offer very wide radiocarbon dates, so it is unclear which of them may be the oldest one. Most of them cluster closely to the older Ukraine Eneolithic sample I5876, but also to later steppe_MLBA samples i.e. Sintashta, Potapovka, and especially Srubna and Andronovo). This points to a genetic continuity from Pre-Corded Ware to Classic and late Corded Ware peoples. Therefore, much like Khvalynsk-Yamna and apparently many other Neolithic cultures, these peoples did not really admix; at least not with the male population.

pca-mittnik-late-neolithic
File modified by me from Mittnik et al. (2018) to include the approximate position of the most common ancestral components, and an identification of potential outliers. Zoomed-in version of the European Late Neolithic and Bronze Age samples. “Principal components analysis of 1012 present-day West Eurasians (grey points, modern Baltic populations in dark grey) with 294 projected published ancient and 38 ancient North European samples introduced in this study (marked with a red outline).

Lucky for us, even though the culture remains undefined, haplogroup R1a-Z645 seems like a unifying trait, as I said long ago, so we only have to wait for more samples to trace their origin. Nevertheless, it is clear that Corded Ware may not have been as genetically homogeneous as Khvalynsk, Yamna and Yamna-related cultures, further supporting its archaeological complexity:

  • Jagodno1 and Jagodno2 (Silesia), dated ca. 2800 BC, show haplogroup G? and I/J? – compatible with an origin of CWC in common with Trypillia (which shows 3 samples of haplogroup G2a2b2a, and one E) and Ukraine Neolithic (showing the expansion of I2a2a1b1 subclades).
  • I7272, from Brandýsek (Czech Republic), dated ca. 2900-2200 BC shows haplogroup I2a2a2 (compatible with an origin in Ukraine Neolithic peoples – this haplogroup is also found in Yamna Kalmykia and in the Yamna Bulgaria outlier, i.e. late western samples from the Early Yamna culture).

NOTE. This precise subclade is only present to date in Chalcolithic samples from Iberia, which points (possibly like the Esperstedt family) to local Central European haplogroups integrated in a mixed Proto-Corded Ware population. The upper subclade I2a2a is found in Neolithic samples from Iberia, the British Isles, Hungary (Koros EN, ALPc), and also south-east European Mesolithic and Neolithic samples.

  • RISE1, from Oblaczkowo (Greater Poland), ca. 2865-2578 BC, shows haplogroup R1b1.
  • The Esperstedt family samples have been analysed as R1a-M417 (xZ645), although the supposed ‘xZ645’ has not been confirmed – not even in the risky new Y-calls from Wang et al. (2018) supplementary materials.
corded-ware-regions-network
Network analysis based on the quantitative occurrence of Corded Ware pottery forms, pottery ornamentation styles, tools,
weapons and ornaments as stated in Table 1, based on the catalogues given in Table 2, line thickness representing similarity

Maybe this heterogeneity is a problem of better defining the culture, but from what we can see the oldest CWC regions and the unifying ‘Corded Ware province’ – formed after ca. 2700 BC by Jutland and Northern Germany, the Netherlands, Saale, Bohemia, Austria and the Upper Danube regions – are for the moment not the most genetically homogeneous groups.

Homogeneity comes later – which we may tentatively identify with the expansion of the A-horizon from the northern Dnieper-Dniester and Lesser Poland area – , as seen around the Baltic (like the Battle Axe culture) with R1a-Z283 subclades, and around Sintashta (i.e. probably Abashevo – Balanovo) with R1a-Z93 subclades, which is compatible with the late spread of different Z645 groups (and potentially a unifying language) .

About Scepters, Horses, and War: on Khvalynsk migrants in the Caucasus and the Danube

steppe-horse-sceptre-khvalynsk

dergachev-scepters-khavlynsk-horsesAbout two months ago I stumbled upon a gem in archaeological studies related to Proto-Indo-Europeans, the book О скипетрах, о лошадях, о войне: этюды в защиту миграционной концепции М.Гимбутас (On sceptres, on horses, on war: Studies in defence of M. Gimbutas’ migration concepts), 2007, by V. A. Dergachev, from the Institute of Cultural Heritage of the Moldavian Republic.

Dergachev’s work dedicates 488 pages to a very specific Final Neolithic-Eneolithic period in the Pontic-Caspian steppe, and the most relevant parts of the book concern the nature and expansion of horses and horse domestication, horse-head scepters, and other horse-related symbology – arguably the most relevant cultural signs associated with Proto-Indo-European speakers in this period.

I haven’t had enough time to read the whole book, but I have read with interest certain important chapters.

About Scepters

Typological classification

The genetic and chronological relationship of horse-head pommel-scepters is classified with incredible detail, to the extent that one could divide subregions among those cultures using them.

khvalynsk-horse-head-scepters
Scheme of regional distribution – chronological – typological development of the carved horse-head stone scepters.

Simplified conclusions of this section include (emphasis mine):

  1. The [horse-head pommel-]scepters arose originally in the depth of the Khvalynsk culture. Following the now well-known finds, they are definitely related to those of the Middle Volga group.
  2. horse-head-pommel-scepters-distribution
    General scheme of genetic and chronological development of carved scepters by visual assessment of morphological details.
  3. In their next modifications, these scepters continued to evolve and develop into the area of the Khvalynsk culture in its latest stages, and possibly later.
  4. Simultaneously, with the same modifications, these scepters “are introduced” into common usage in the Novodanilovka culture, which in its spread by one wing was in contact and interspersed immediately with the area of Khvalynsk remains; and on the other hand, far in the south – in the Pre-Kuban and Ciscaucasian regions – within the range of the Domaikopska culture; and in the west – in the Carpathian – Post-Kuban – with the areas of early agricultural cultures Cucuteni A – Trypillia B1, Gumelnița-Karanovo VI.
  5. The simultaneous presence in the areas of the Ciscaucasian, Carpatho-Danubian, and especially Novodinilovka cultures, whose carriers continue the Khvalynian traditions of making stone scepters, and the scepters themselves (in their non-functional implication in the local cultural environment), all definitely allow us to view these findings as imported Novodanilovka objects.

Cultural relevance of scepters

The text goes on to make an international comparison of scepters and their relevance as a cultural phenomenon, with its strong symbolic functions as divine object, its use in times of peace, in times of war, and in a system of ritual power.

horse-scepters-steppe
Restoration of V. A. Dergachev: a) model for restoration – Paleolithic and Neolithic wands; b) the expected appearance of the Eneolithic scepter on the handle with a coupling (according to Dergachev 2007).
Especially interesting is the section dedicated to Agamemnon’s scepter in the Iliad, one of the oldest Indo-European epics. Here is an excerpt from Illiad II.100-110 (see here the Greek version) with the scepter’s human and divine genealogy:

Then among them lord Agamemnon uprose, bearing in his hands the sceptre which Hephaestus had wrought with toil. Hephaestus gave it to king Zeus, son of Cronos, and Zeus gave it to the messenger Argeïphontes; and Hermes, the lord, gave it to Pelops, driver of horses, and Pelops in turn gave it to Atreus, shepherd of the host; and Atreus at his death left it to Thyestes, rich in flocks, and Thyestes again left it to Agamemnon to bear, that so he might be lord of many isles and of all Argos.

About the horse

His studies on horse remains show an interesting, detailed quantitative and statistical approach to the importance and (cultural and chronological) origin of horses (and likely horse domestication) in each culture.

Although the part on horse remains is probably a bit outdated today, after many recent studies of Eneolithic steppe sites (see here one example), it still shows the relative distribution of horse bone remains among different steppe cultures, which is probably similar to what could be reported today:

distribution-horses-steppe-eneolithic
Territorial distribution of horse remains in the Middle Eneolithic period. Absolute and relative numbers.

Even more interesting is the relationship of the distribution of horse remains with archaeological complexes and horse-related symbols. Some excerpts from the conclusions of this section:

  1. Accounting and analysis of archeo-zoological and archaeological data proper for a horse for a vast area from the Tisza and the Middle Danube to the Caucasus and the Urals (which includes the main cultures of the western agricultural, Caucasian, and Eastern European cultural zones) clearly points to the eastern cultural zone as a zone of the originally the most important social significance of a horse as the only possible zone of the earliest domestication, horseback riding and all-round use of a horse. In relation to the eastern, the western land – the ancient Carpatho-Danubian or the Caucasian cultural zones – are secondary and subordinate to the first on the phenomenon under consideration.
  2. horse-symbols
    Horse-shaped hanger-amulets made of bone.
  3. The first quantitative leap in the manifestation of the remnants of a horse, marking itself and the first qualitative changes in the social status of this animal, is due mainly to the Middle Volga culture of the developed Neolithic of the Middle Volga region (in part, the Southwest Urals), which, accordingly, determine the cultural context, time and geographic region – or, the initial, single and main epicenter of the process of taming and domestication of a horse.
  4. On the one hand, the subsequent substantial increase in the number of horse remnants, and, on the other, the wide inclusion of the horse in cults, rituals, funerary rituals (horse pendants, ornamented metacarpus, horse bones, sacrificial altars) in the Samara culture of the Early Eneolithic of the same region definitely indicates the continuing increase in the social significance of this species of animal, which was most likely expressed in the final design of a specialized horse breeding culture and, accordingly, in a wide range of applications using a horse for riding. At the same time, we can observe the beginning of the transfer of the already domesticated horse from the original historical and geographic epicenter to other cultures of the eastern cultural zone and, in part, the cultures closest to the periphery of this zone, into the western agricultural zone (Bolgrad-Aldeni P, Pre-CuCuteni-Trypillya A) .
  5. expansion-horse-steppe
    Schematic depiction of cultures and regional-chronological distribution of percentage of horse remains. (Depicted are arrows from Middle Volga and Samara culture to the rest)
  6. Middle Eneolithic – early stages. One of the leading places in the remnants of the horse is in the Middle Volga region, the Khvalynsk culture. Genetically related to the Samara, the Khvalynsk I culture preserves the traditions of the ritual, cultural meaning, the treatment of the image of a horse in funerals (altars, horse bones, funerary rituals). But, At the same time, it is in this precise culture that the image of the horse, included in the social symbolism (horse-head pommel-scepter), for the first time it acquires a special, maximum social significance. That is why the appearance and subsequent widespread distribution of the social symbols in Novodanilovka-type objects can definitely be considered as another qualitative leap in the social significance of a horse – its use for military purposes for close and distant expeditions. And such an interpretation is fully confirmed from the analysis of Novodanilovka-type objects, which is the subject of discussion.
  7. Judging by the osteological data and the typological evolution of the horse-head scepters, the Khvalynian culture and remains of the Novodanilovka type are already associated with the relatively widespread and intensive findings of domesticated horses in various areas of the eastern cultural zone (semi-desert regions of the Lower Volga and the Caspian region – Khvalynsk culture, forest-steppe and steppe from the Volga to the Dnieper – Sredni Stog, Repin cultures), and the western – agricultural (Gumelnitsa, Cucuteni A-Tripolye Bl), and the Caucasus (Pre-Maykop) zones, where, however, the horse played a very modest role.

  9. From the functional point of view, according to the sum of the data, there is no reason to doubt that in the eastern zone the horse is already present in the Late Neolithic period. Since its domestication and the emergence of a specialized horse breeding, it has been also widely used for meat, milk and dairy products (including the traditional hippace tradition of the later Scythians), and since the beginning of the early Eneolithic for transport and for riding purposes. Another thing is the horse as a means of war, a means of distant travel and expansion. The beginning of the use of a horse for these purposes, in the opinion of the author, is determined by the appearance of social symbolism in the form of horse-head scepters, and is most fully reflected in the memories of the Khvalynsk culture and, in particular, the Novodanilovka type. Concerning western or Caucasian cultural zones related to Khvalynsk, the horse is thought to have been linked to the eastern region, used mainly for riding, as a means of transport and for communication, which, however, does not exclude its use for meat.

These are the main conclusions-interpretations, suggesting the analysis and archaeological and other sources containing information about the horse. And as for our pommel-scepters, then, as can be seen from these sources, the main thing is that the culture of the Middle Volga region, according to all the data, definitely accumulates in itself the longest traditions associated with the gradual increase of social significance of the horse. And if so, this circumstance motivates the possibility or necessity of appearing in the environment of the bearers of this culture of unique signs-symbols that carry within themselves or reflect the image of this animal as an extremely significant social reality. The revealed and characterized quality, as a matter of fact, fill or open by themselves the hypothetical elements we have previously identified, the meanings of that particularity, folded in the social sign-symbol, in our case – the horse-head-shaped scepter.

The relevance of Dergachev’s work

As you certainly know by now if you are a usual reader of this blog, there were two other seminal publications that same year correcting and expanding Gimbutas’ model:

Each one of these works taken independently (especially the books) may give a different version of Proto-Indo-European migrations; Anthony and Dergachev are heirs of Gimbutas’ simplistic kurgan-based model, and of other previous, now rejected ideas, and they reflect them whenever they don’t deal with first-hand investigation (and even sometimes when interpreting their own data). Taken together – and especially in combination with recent genetic studies – , though, they describe a clearer, solider model of how Proto-Indo-Europeans developed and expanded.

distribution-scepters-steppe
Distribution of horse-head scepters, according to Dergachev, Sorokin (1986).

Anthony’s publication overshadowed the importance of Dergachev’s work for the English-speaking world – and by extension for the rest of us. However, V. A. Dergachev’s updated study of his previous work on steppe cultures shows the right, thorough, and diligent way of describing the expansion of early Khvalynsk-Novodanilovka chieftains with the horse and horse symbolism into the Caucasus and the Lower Danube (like the seminal work of Harrison & Heyd 2007 described the expansion of Yamna settlers with East Bell Beakers, culturally opposed to Corded Ware and to the Proto-Beakers). On the other hand, Anthony’s broad-brush, superficial description of thousands of years of potential Indo-European-speaking peoples gave a migration picture that – although generally right (like radiocarbon-based Iberian origin of the Bell Beaker culture was right) – was bound to be wrong in some essential details, as we are seeing in archaeology and genetics.

NOTE. As I have said before, Anthony’s interpretations of Sredni Stog culture representing a sort of ‘peasants’ under the rule of Novodanilovka chiefs was based on old theories of Telegin, who changed his mind – as did the rest of the Russian school well before the publication of Dergachev’s book, considering both as distinct cultural phenomena. Anthony selected the old interpretation, not to follow a Gimbutas / Kristiansen model of Sredni Stog being Indo-European and expanding with GAC into Corded Ware (because, for him, Corded Ware peoples were originally non-Indo-European speakers): he seems to have done it to prove that Proto-Anatolian traveled indeed through the North Pontic area, i.e. to avoid the regional ‘gap’ in the maps, if you like. Then with the expansion of Repin over the area, Sredni Stog peoples would have been absorbed. With genetic investigation, as we know, and with this kind of detailed archaeological studies, the traditional preference for “large and early” IE territories – proper of the mid-20th century – are no longer necessary.

Steppe Eneolithic

We already had in 2016 a Samara hunter-gatherer sample dated ca. 5600 BC, representative of EHG ancestry, of haplogroup R1b1a. We also had three early Khvalynsk samples from Samara Eneolithic dated ca. 4600 BC, with a drift towards (what we believe now is) a population from the Caucasus, showing haplogroups Q1a, R1a1(xM198), and R1b1a, the last one described in its paper as from a high-status burial, similar to high-status individuals buried under kurgans in later Yamna graves (of R1b-L23 lineages), and therefore likely a founder of an elite group of patrilineally-related families, while the R1a1 sample showed scarce decoration, and does not belong to the M417 lineage expanded later in Sredni Stog or Corded Ware.

In 2017 we knew of the Ukraine_Eneolithic sample I6561, from Alexandria, of a precise subclade (L657) of haplogroup R1a-Z93, dated ca. 4000 BC, and likely from the Sredni Stog (or maybe Kvitjana) culture. This sample alone makes it quite likely that the expansion of R1a-Z645 subclades happened earlier than expected, and that it was associated with movements along forest-steppe cultures, most likely along the Upper Dniester or Dnieper-Dniester corridor up to the Forest Zone.

We have now confirmation that Khvalynsk samples from the Yekaterinovka Cape settlement ca. 4250-4000 BC were reported by a genetic lab (to the archaeological team responsible) as being of R1b-L23 subclades, although the precise clades (reported as P312 and U106) are possibly not accurate.

NOTE. Curiously enough, and quite revealing for the close relationship of scepters to the ritual source of power for Khvalynsk chieftains (political and/or religious leaders), the scepter found in the elite burial 45 of the Ekaterinovka cape (a riverine settlement) shows a unique zoomorphic carving, possibly resembling a toothed fish or reptile, rather than the most common horse-related motifs of the time.

With Wang et al. (2018), a real game-changer in the Khvalynsk – Sredni Stog (and also in the Yamna/Bell Beaker – Corded Ware) opposition, we also know that two Steppe Eneolithic samples from the Northern Caucasus Piedmont, dated ca. 4300-4100 BC, show haplogroup R1b1. Although its direct connection to the expansion of early Khvalynsk with horse-related symbolism is not clear from the archaeological information shared (none), this is what the paper has to say about them:

The two distinct clusters are already visible in the oldest individuals of our temporal transect, dated to the Eneolithic period (~6300-6100 yBP/4300-4100 calBCE). Three individuals from the sites of Progress 2 and Vonjuchka 1 in the North Caucasus piedmont steppe (‘Eneolithic steppe’), which harbor Eastern and Caucasian hunter-gatherer related ancestry (EHG and CHG, respectively), are genetically very similar to Eneolithic individuals from Khalynsk II and the Samara region19, 27. This extends the cline of dilution of EHG ancestry via CHG/Iranian-like ancestry to sites immediately north of the Caucasus foothills.

In contrast, the oldest individuals from the northern mountain flank itself, which are three first degree-related individuals from the Unakozovskaya cave associated with the Darkveti-Meshoko Eneolithic culture (analysis label ‘Eneolithic Caucasus’) show mixed ancestry mostly derived from sources related to the Anatolian Neolithic (orange) and CHG/Iran Neolithic (green) in the ADMIXTURE plot (Fig. 2C). While similar ancestry profiles have been reported for Anatolian and Armenian Chalcolithic and Bronze Age individuals20, 23, this result suggests the presence of the mixed Anatolian/Iranian/CHG related ancestry north of the Great Caucasus Range as early as ~6500 years ago.

On the specific burials, we have e.g. the recent open access paper New cases of trepanations from the 5th to 3rd millennia BC in Southern Russia in the context of previous research: Possible evidence for a ritually motivated tradition of cranial surgery?, by Gresky et al. J Am Phys Anthropol (2016):

During the late 5th millennium BC, cultural groups of the Eneolithic occupied the northern circumpontic area and the areas between the North Caucasus and the Lower Volga. For the first time, individual inhumations were placed below low burial mounds (Rassamakin, 2011). During the 4th millennium BC, the area split into two cultural spheres. In the northern steppe area communities continued with the burial practice of crouched inhumations below low mounds, with this culturally transforming into the early Pit Grave culture. In contrast, in the Caucasian foothill zone and the neighbouring steppe, the Majkop-Novosvobodnaya culture emerged (Kohl and Trifonov, 2014). Similarly, during the 3rd millennium BC, two cultural spheres influenced the area: The North Caucasian Culture dominated the Caucasian foothills for the next five centuries, while in the steppe area between the Lower Don and the Caucasus, regional groups of the Catacomb Culture existed side-by-side.

Burials of the Eneolithic epoch (late 5th millennium BC)

The oldest group of individuals with trepanations are found in the North Caucasian variant of the late circumpontic Eneolithic and date to the last third of the 5th millennium BC (Korenevsky, 2012). Burials of this epoch are inhumations in shallow pits, chiefly without burial goods, but covered with large quantities of red ochre. Of special interest is a collective burial of seven individuals from VP 1/12, who were interred together in a secondary burial ritual. The sites of Tuzluki, Mukhin, Voinuchka, Progress, and Sengileevskii all belong to this period.

An EHG and a Caucasus ‘clouds’ have been drawn, leaving Pontic-Caspian steppe and derived groups between them.See the original file here.

Without the datasets to test different models, you can only imagine what is happening with the processed, secondary data we have. The position of Eneolithic Steppe cluster in the PCA (probably Khvalynsk-related peoples already influenced by the absorbed, previous Caucasus population), as well as other potential Caucasus groups intermediate between Steppe Maykop and Caucasus Maykop (as suggested by other ancient and modern Caucasus samples), may indicate that Yamna is between Khvalynsk and such intermediate Caucasus populations (as the source of the additional CHG-related ancestry) and – as the paper itself states – that it also received additional EEF contribution, probably from the western cultures absorbed during these Khvalynsk-Novodanilovka migrations (or later during Khvalynsk/Repin migrations).

Also interpreted in light of these early Khvalynsk-Novodanilovka migrations of horse riding chieftains (and their close contacts with the Caucasus), you can clearly see where the similar CHG-like contribution to Ukraine Eneolithic and other North Pontic forest-steppe cultures (which later contributed to Proto-Corded Ware peoples) must have come from. The simplistically reported proportions of EHG:CHG:EEF ancestry might be similar in many of these groups, but the precise origin and evolution of such ancestral components is certainly not the same: statistical methods will eventually show this, when (and if) we have many more samples, but for the moment Y-DNA is the most obvious indicator of such differences.

There was no steppe people speaking a steppe language AKA immutable Proto-Indo-European: the glottochronological models spanning thousands of years are not valid for the steppe, just as they are not valid for an Anatolian homeland, nor for a Caucasus homeland. The actual cultural-historical early Sredni Stog – Khvalynsk community, formed earlier than ca. 5000 BC, is a thousand years older than the expansion of Khvalynsk with the horse, and some two thousand years older than the expansion of Khvalynsk-Repin/Early Yamna migrants (see here for the latest genetic research).

What lies between the formation of that early Eneolithic cultural-historical community, and what we see in archaeology and genetics in Middle and Late Eneolithic steppe cultures, is the radical differentiation of western (Ukraine Eneolithic, mainly forest-steppe) and eastern (Samara and Khvalynsk/Repin, mainly steppe) cultures and peoples, i.e. precisely the period of differentiation of an eastern, Proto-Indo-Hittite-speaking early Khvalynsk community (that expanded with the horse and horse-related symbols) from a western, probably Early Proto-Uralic speaking community of the North Pontic forest-steppe cultural area.

NOTE. I am not against a Neolithic ‘steppe’ language. But this steppe language was spoken before and/or during the first Neolithisation wave, and should be associated with Indo-Uralic. If there was no Indo-Uralic language, then some communities would have developed Early Proto-Indo-European and Early Proto-Uralic side by side, in close contact to allow for dozens of loanwords or wanderwords to be dated to this period (where, simplistically, PIH *H corresponds to EPU *k, with some exceptions).

steppe-forest-change
Map of a) steppe – forest-steppe border during the Eneolithic in the Pontic-Caspian region and b) the border today, showing a more limited steppe zone in the North Pontic area (reason for the specific ways of expansion of horse-related cultures and horse-related nomadic pastoralism during the Eneolithic).

The convergence that we see in PCA and Admixture of Yamna and the earliest Baltic LN / Corded Ware ‘outlier’ samples (if not directly related exogamy of some Baltic LN/CWC groups with Yamna migrants, e.g. those along the Prut), must be traced back to the period of genetic drift that began precisely with these Khvalynsk-Novodanilovka expansions, also closely associated with populations of the Caucasus, thus bringing North Pontic forest-steppe cultures (probably behind Proto-Corded Ware peoples) nearer to Khvalynsk, and both by extension to Yamna.

We have seen this problem arise in Bell Beaker samples expanding all over Europe, turning from a fully Yamnaya-like population to something else entirely in different regions, from more EEF-like to more CWC-like, sharing one common trait: Y-DNA. We are seeing the same happen with Balkan groups and Mycenaeans, with Old Hittites, and with steppe MLBA from Andronovo peoples expanding over Central and South Asia, and we know that patrilineal clans and thus Y-chromosome bottlenecks were common after Neolithisation, especially with nomadic pastoralist steppe clans (and probably also with many previous population expansions).

Steppe Eneolithic peoples were thus no different to other previous and posterior expanding groups, and ancestry is going to be similar for people living in neighbouring regions, so Y-DNA will remain the essential tool to distinguish different peoples (see here a summary of Proto-Indo-Europeans expanding R1b-L23).

We are nevertheless still seeing “R1b zombies” (a quite appropriate name I read on Anthrogenica) still arguing for a Western European origin of R1b-L23 based on EEF-like ancestry and few steppe-related contribution found in Iberian Bell Beakers (read what David Reich has to say on this question); and “OIT zombies” still arguing for IVC representing Proto-Indo-European, based on Iran_N ancestry and the minimal steppe ancestry-related impact on certain ancient Asian cultures, now partly helped by “Caucasus homeland zombies” with the new PIE=CHG model; apart from many other pet theory zombies rising occasionally from their graves here and there. Let’s hope that this virus of the undead theories does not spread too strongly to the R1a-Indo-European association, when the official data on Khvalynsk, West Yamna, and Yamna Hungary come out and show that they were dominated by R1b-L23 lineages.

Because we need to explore in detail the continuation of Khvalynsk-related (potential Proto-Anatolian) cultures in the Lower Danube and the Balkans, e.g. from Cernavoda I to Cernavoda III, then maybe to Ezero, and then to Troy; as well as the specific areas of Late Indo-European expansions associated with Early Yamna settlers turning into Bell Beakers, Balkan EBA, and Steppe MLBA-associated cultures. There is a lot of work to do on proper definition of Bronze Age cultures and their potential dialects, as well as convergence and divergence trends, and not only of Indo-European, but also of Uralic-speaking communities derived from Corded Ware cultures.

If we let the narratives of the 2000s in Genetics (in combination with the 1960s in Archaeology) dominate the conversation, then a lot of time will be absurdly lost until reality imposes itself. And it will.

The Danube Corridor Hypothesis and the Carpathian Basin in the Aurignacian

palaeolithic-migrations

Open access review, The Danube Corridor Hypothesis and the Carpathian Basin: Geological, Environmental and Archaeological Approaches to Characterizing Aurignacian Dynamics, by Wei Chu, J World Prehist (2018).

Abstract (emphasis mine):

Early Upper Paleolithic sites in the Danube catchment have been put forward as evidence that the river was an important conduit for modern humans during their initial settlement of Europe. Central to this model is the Carpathian Basin, a region covering most of the Middle Danube. As the archaeological record of this region is still poorly understood, this paper aims to provide a contextual assessment of the Carpathian Basin’s geological and paleoenvironmental archives, starting with the late Upper Pleistocene. Subsequently, it compiles early Upper Paleolithic data from the region to provide a synchronic appraisal of the Aurignacian archaeological evidence. It then uses this data to test whether the relative absence of early Upper Paleolithic sites is obscured by a taphonomic bias. Finally, it reviews current knowledge of the Carpathian Basin’s archaeological record and concludes that, while it cannot reject the Danube corridor hypothesis, further (geo)archaeological work is required to understand the link between the Carpathian Basin and Central and Southeastern Europe.

Interesting excerpt:

Though the Carpathian Basin record currently supports the idea of an exogenous, early entrance of the early Upper Paleolithic into the Carpathian Basin unrelated to any of the preceding MP or transitional industries, the dispersal across the Carpathian Basin is not suggestive of rapid demic expansion, as is evidenced by the relatively late hybridization of the Peștera cu Oase fossil and implied by persistent Mousterian technological elements (Fu et al. 2015; Horvath 2009; Noiret 2005).

Red stars indicate major archaeological sites; black stars indicate minor archaeological sites. Blue circles indicate modern human remains and black circles are loess profiles (see Tables 1 and 3 for locality information). Projection is latitude–longitude WGS84; DEM is SRTM (Color figure online)”

This begs the question of where the makers of the early Upper Paleolithic in the Carpathian Basin came from. Aside from a handful of Aurignacian sites (e.g. Bacho Kiro, Temnata) and Kozarnika, whose link to the Aurignacian remains tenuous, no other sites directly connect the Carpathian Basin Aurignacian to the south in the Balkans. Additionally, Anatolia has also to provide empirical evidence of a connection between Southwestern Europe and the early hominin technocomplexes of the Levant. Therefore, a western source for the Carpathian Basin early Upper Paleolithic is conceivable, especially considering the early Willendorf dates which, if correct, pre-date any of the evidence in the Carpathian Basin. If the Danube was as easy a conduit as has been suggested, it is equally likely that it may have seen hominin movement in the opposite direction (Sitlivy et al. 2014). Indeed, increasing genetic and archaeological evidence (Adler et al. 2008; Anikovich et al. 2007; López et al. 2016) supports the idea that the earliest modern humans coming from the Middle East and into Europe may have bypassed Southeastern Europe (at least overland), opting for a route running through the Caucasus, dispersing east through the East European Plain and then north of the Carpathians.

The recent reanalysis of Central European early Upper Paleolithic assemblages and possibly Initial Upper Paleolithic sensu lato finds farther east in the geographically connected Moravian Plains (Bohunician) suggests that early modern humans were present in Central Europe far sooner than previously recognized (Müller et al. 2011; Nigst et al. 2014; Richter et al. 2008, 2009). This notion could lead to a major modification in our understanding of the origin and cultural ontogeny of the Aurignacian technocomplex (Sitlivy et al. 2014).

This suggests that while hominins were undoubtedly present within the Middle Danube catchment in the late Upper Pleistocene, it is currently difficult to tell from the archaeological record whether they entered the Carpathian Basin on direct ‘highways’, in waves (Hublin 2015), or more piecemeal; furthermore, the evidence is too sparse to suggest a directional trajectory. Indeed, the gap in the Danube record suggests that the situation may be more complicated than has previously been thought. Furthermore, climatic reconstructions, illustrated by advances in loess stratigraphy, faunal/floral records and geochemistry, suggest a necessary diversion from the rugged karstic regions of the basin that may have been more familiar hunting areas for previous (Neanderthal) populations. This may have resulted in more frequent or seasonal use of the lowlands within the earlier parts of MIS 3 that may have prompted subsequent modifications in hominin subsistence behavior. A prolonged/intense modern human presence in the Carpathian Basin throughout the late Upper Pleistocene is testified to by a higher frequency of lithic sites with increased artifact density. Increased sedimentation rates in the later part of the Pleistocene may have also helped to offset the palimpsest effect that might have skewed the record.

Consequences of O&M 2018 (II): The unsolved nature of Suvorovo-Novodanilovka chiefs, and the route of Proto-Anatolian expansion

neolithic_steppe-suvorovo

This is part of a series of posts analyzing the findings of the recent Nature papers Olalde et al.(2018) and Mathieson et al.(2018) (abbreviated O&M 2018).

I already expressed my predictions for 2018. One of the most interesting questions among them is the identification of the early Anatolian offshoot, and this is – I believe – where Genomics has the most to say in Indo-European migrations.

Linguistics and Archaeology had already a mainstream account from Late PIE/Yamna onwards, and it has been proven right in Genomic investigation. There is, however, no consensus on Indo-Hittite.

Suvorovo-Novodanilovka

Apart from the Anatolian homeland hypothesis and its westward migration (as referenced e.g. by Lazaridis et al. 2017), the other possibility including the most likely steppe homeland is that Proto-Anatolian spread through the Balkans, and must have separated from Khvalynsk and travelled first westward through the North Pontic region, and then southward to Ezero.

EDIT (10 MAR 2018): The Anatolian westward route within the steppe homeland model refers to the possibility that Proto-Anatolian spread south through the Caucasus, and then westward through Anatolia, as suggested e.g. originally by Marija Gimbutas for Maykop, as a link in the Caucasus.

We all know that this Khvalynsk -> Novodanilovka-Suvorovo -> Cernavoda -> Ezero -> Troy migration model proposed by Anthony shows no conspicuous chain in Archaeology, but obvious contacts (including Genomics) are seen among some of these neighbouring cultures in different times.

We know that remains of Suvorovo-Novodanilovka culture of chiefs emerged around 4400-4200 BC among ordinary local Sredni Stog settlements:

  • the Novodanilovka rich burials in the steppes, near the Dnieper,
  • and the Suvorovo group in the Danube delta, roughly coinciding with the massive abandonment of old tell settlements in the area.

One of the strongest cultural connections between Khvalynsk and Suvorovo Novodanilovka chiefs is the similar polished stone mace-heads shaped like horse heads found in both cultures, a typical steppe prestige object going back to the east Pontic-Caspian steppe beginning ca. 5000-4800 BC.

Its finding in the Danube valley may have signalled the expansion of horse riding, which is compatible with the finding of ancient domesticated horses in the region. Horses were not important in Old European cultures, and it seems that they weren’t in Sredni Stog or Kvitjana either.

sredni-stog-suvorovo-novodanilovka-cernavoda
Steppe and Danubian sites at the time: of the Suvorovo-Novodanilovka intrusion, about 4200-3900 BC. David W. Anthony (2007).

NOTE. Telegin, the main source of knowledge in Ukraine prehistoric cultures for Anthony, was eventually convinced that Surovovo-Novodanilovka was a separate culture. However, for Anthony (using Telegin’s first impressions), it may have been a wealthy elite among Sredni Stog peoples. Anthony considers Sredni Stog to have been also influenced by Khvalynsk, and thus potentially related to the Suvorovo-Novodanilovka chiefs.

Nevertheless, he obviously cannot link North Pontic Eneolithic cultures to Khvalynsk nor to horse riding – whilst he clearly assumes horse riding for Novodanilovka-Suvorovo chiefs – , and he does not link North Pontic cultures to later expansions of Late Proto-Indo-Europeans from late Khvalynsk and Yamna, either.

The question here for Anthony (as with further Proto-Anatolian expansions described in his 2007 book), in my opinion, was to offer a plausible string of connections between Khvalynsk and Anatolia, and the simplest connection one can make among steppe cultures is a general, broad community between North Pontic and North Caspian cultures. That way, the knot tying Khvalynsk to the Danube seems stronger, whatever the origin of Suvorovo-Novodanilovka chiefs.

If, however, a direct genetic connection is made between Suvorovo-Novodanilovka chiefs and Khvalynsk – as in its association with R1b-M269 and R1b-L23 lineages – , there will be little need to include Sredni Stog or any other intermediate culture in the equation.

We have already seen a movement of steppe ancestry into mainland Greece, and I would not be surprised if a parallel movement could be seen from Ezero to Troy (or a neighbouring North-West Anatolian region), so that the final migration of Common Anatolian had in fact been triggered by the massive steppe migrations during the Chalcolithic.

NOTE. Whereas we are certain to find R1b-L23 subclades in the direct Balkan migrations from Yamna, the link of steppe->Anatolia migrations may be a little trickier: even if we find out that the Suvorovo-Novodanilovka expansion was associated with an expansion and reduction of haplogroup variability (to haplogroups R1b-M269 and R1b-L23), we don’t know yet if the ca. 1,500 years passed (and the different cultural and population changes occurred) between Proto-Anatolian and Common Anatolian migrations may have impacted the main haplogroup composition of both communities.

O&M 2018

A probably unsurprising – because of its previously known admixture and PCA – , but nevertheless disappointing finding came from the Y-SNP call of the haplogroup R1 found in Varna (R1b-V88, given first by Genetiker), leaving us with no new haplogroup data standing out for this period.

This sample’s lack of obvious genetic links with the steppe and early date didn’t deter me from believing it could show subclade M269, and thus a sign of incoming Suvorovo chiefs in the region. After all, R1b-P297 subclades seemed to have almost disappeared from the Balkans by that time, and we know that assessments based only on ancestral components and PCA clusters are not infallible – we are seeing that in many, many samples already.

Țerna S., Govedarica B. (2016)

NOTE. In fact, the first time I checked Mathieson et al. (2018) supplementary tables I thought that the ‘Ukraine_Eneolithic’ sample of R1b-L23 subclade was ‘it’: the first clear proof in ancient samples of incoming Suvorovo chiefs from Khvalynsk I was looking for…Until I realized its date, and that it was more likely a Late Yamna (or Catacomb) sample.

Steppe ancestry is found in the Varna and Smyadovo outliers, though, and these samples cluster closely to Ukraine Eneolithic samples (which are among Khvalynsk, Ukraine Neolithic, and Anatolia Neolithic clusters), so some population movement must have happened around or before that time in the region, and it is obvious that it happened from east to west.

It remains to be seen, therefore:

a) If the incoming Suvorovo-Novodanilovka chiefs (most likely originally from Khvalynsk) dominating over North Pontic and Danube regions show – as I bet – R1b-M269, and possibly also early R1b-L23* subclades,

b) Or else they still show mixed lineages, reflecting an older admixed population of the Pontic-Caspian steppe – as the early Khvalynsk and Ukraine Eneolithic samples we have now.

NOTE. Even though my preferred model of migration is through the Balkans – due to the many east-west migrations seen from the steppe into Europe – , there is no general consensus here because of the lack of solid anthropological models, and there are cultural links found also between the steppe and Anatolia through the Caucasus, so the question remains open.
