Sorry for the last weeks of silence, I have been rather busy lately. I am having more projects going on, and (because of that) I also wanted to finish a project I have been working on for many months already.
I have therefore decided to publish a provisional version of the text, in the hope that it will be useful in the following months, when I won’t be able to update it as often as I would like to:
EDIT (20 JAN 2019): For those of you who are more comfortable reading in your native language, I have placed some links to automatic translations by Google Translate. They might work especially well for the texts of A Game of Clans & A Clash of Chiefs.
Don’t forget to check out the maps included in the supplementary materials: I have added Y-DNA, mtDNA, and ADMIXTURE data using GIS software. The PCA graphics are also important to follow the main text.
NOTE. Right now the files are only in my server. I will try to upload them to Academia.edu and Research Gate when I have time, I have uploaded them to Academia.edu and ResearchGate, in case the websites are too slow.
I would have preferred to wait for a thorough revision of the section on archaeology and the linguistic sections on Uralic, but I doubt I will have time when the reviews come, so it was either now or maybe next December…
I say so in the introduction, but it is evident that certain aspects of the book are tentative to say the least: the farther back we go from Late Proto-Indo-European, the less clear are many aspects. Also, linguistically I am not convinced about Eurasiatic or Nostratic, although they do have a certain interest when we try to offer a comprehensive view of the past, including ethnolinguistic identities.
I cannot be an expert in everything, and these books cover a lot. I am bound to publish many corrections as new information appears and more reviews are sent. For example, just days ago (before SNP calls of Wang et al. 2018 were published) some paragraphs implied that AME might have expanded Nostratic from the Middle East. Now it does not seem so, and I changed them just before uploading the text. That’s how tentative certain routes are, and how much all of this may change. And that only if we accept a Nostratic phylum…
NOTE. Since the first book I wrote was the linguistic one, and I have spent the last months updating the archaeology + genetics part, now many of you will probably understand 1) why I am so convinced about certain language relationships and 2) how I used many posts to clarify certain ideas and receive comments. Many posts offer probably a good timeline of what I worked with, and when.
A Song of Sheep and Horses (ASoSaH) reread
Edit (23 Jan 2019):
To be able to revise and update the text properly, I decided to start a series of posts on different aspects.
I did not add this section to the books, because they are still not ready for print, but I think this is due somewhere now. It is impossible to reference all who have directly or indirectly contributed to this, so this is a list of those I feel have played an important role.
I am indebted to the following people (which does not mean that they share my views, obviously):
First and foremost, to Fernando López-Menchero, for having the patience to review with detail many parts on Indo-European linguistics, knowing that I won’t accept many of his comments anyway. The additional information he offers is invaluable, but I didn’t want to turn this into a huge linguistic encyclopaedia with unending discussions of tiny details of each reconstructed word. I think it is already too big as it is.
I would not have thought about doing this if it were not for the interest of Wekwos (Xavier Delamarre) in publishing a full book about the Indo-European demic diffusion model (in the second half of 2017, I think). It was them who suggested that I extended the content, when all I had done until then was write an essay and draw some maps in my free time between depositing the PhD thesis and defending it.
Sadly, as much as I would like to publish a book with a professional publisher, I don’t think ancient DNA lends itself for the traditional format, so my requests (mainly to have free licenses and being able to review the text at will, as new genetic papers are published) were logically not acceptable. Also, the main aim of all volumes, especially the linguistic one, is the teaching of essentials of Late Proto-Indo-European and related languages, and this objective would be thwarted by selling each volume for $50-70 and only in printed format. I prefer a wider distribution.
At first I didn’t think much of this proposal, because I do not benefit from this kind of publications in my scientific field, but with time my interest in writing a whole, comprehensive book on the subject grew to the point where it was already an ongoing project, probably by the start of 2018.
I would not have been in contact with Wekwos if it were not for user Camulogène Rix at Anthrogenica, so thanks for that and for the interest in this work.
I would not have thought of writing this either if not for the spontaneous support (with an unexpected phone call!) of a professor of the Complutense University of Madrid, Ángel Gómez Moreno, who is interested in this subject – as is his wife, a professor of Classics more closely associated to Indo-European studies, and who helped me with a search for Indo-Europeanists.
EDIT (1 JAN 2019): I remembered that Karin Bojs sent me her book after reading the demic diffusion model. I may have also thought about writing a whole book back then, but mid-2017 is probably too early for the project.
Professor Kortlandt is still to review the text, but he contributed to both previous essays in some very interesting ways, so I hope he can help me improve the parts on Uralic, and maybe alternative accounts of expansion for Balto-Slavic, depending on the time depth that he would consider warranted according to the Temematic hypothesis.
The maps are evidently (for those who are interested in genetics) in part the result of the effort of the late Jean Manco: As you can see from the maps including Y-DNA and mtDNA samples, I have benefitted from her way of organising data and publishing it. Similarly, the work of Iain McDonald in assessing the potential migration routes of R1b and R1a in Europe with the help of detailed maps was behind my idea for the first maps, and consequently behind these, too.
Readers of this blog with interesting comments have also been essential for the improvement of the texts. You can probably see some of your many contributions there. I may not answer many comments, because I am always busy (and sometimes I just don’t have anything interesting to say), but I try to read all of them.
Users of other sites, like Anthrogenica, whose particular points of view and deep knowledge of some very specific aspects are sometimes very useful. In particular, user Anglesqueville helped me to fix some issues with the merging of datasets to obtain the PCAs and ADMIXTURE, and prepared some individual samples to merge them.
Even without posting anything, Google Analytics keeps sending me messages about increasing user fidelity (returning users), and stats haven’t really changed (which probably means more people are reading old posts), so thank you for that.
NOTE. I understand that writing a paper requires a lot of work, and probably statistical methods are the main interest of authors, editors, and reviewers. But it is difficult to comprehend how any user of open source tools can instantly offer a more complex assessment of the samples’ Y-SNP calls than professionals working on these samples for months. I think that, by now, it should be clear to everyone that Y-DNA is often as important (sometimes even more) than statistical tools to infer certain population movements, since admixture can change within few generations of male-biased migrations, whereas haplogroups can’t…
Srubna-Andronovo samples are as homogeneous as they always were, dominated by R1a-Z645 subclades and CWC-related (steppe_MLBA) ancestry.
The appearance of one (possibly two) R-Z280 lineages in this mixed Srubna-Alakul region of the southern Urals and this early (1880-1690 BC, hence rather Pokrovka-Alakul) points to the admixture of R1a-Z93 and R1a-Z280 already in Abashevo, which also explains the wide distribution of both subclades in the forest zones of Central Asia.
If Abashevo is the cornerstone of the Indo-Iranian / Uralic community, as it seems, the genetic admixture would initially be quite similar, undergoing in the steppes a reduction to haplogroup R1a-Z93 (obviously not complete), at the same time as it expanded to the west with Pokrovka and Srubna, and to the east with Petrovka and Andronovo. To the north, similar reductions will probably be seen following the Seima-Turbino phenomenon.
NOTE. Another R1a-Z280 has been found in the recent sample from Bronze Age Poland (see spreadsheet). As it appears right now in ancient and modern DNA, there seems to be a different distribution between subclades:
R1a-Z280 (formed ca. 2900 BC, TMRCA ca. 2600 BC) appears mainly distributed today to the east, in the forest and steppe regions, with the most ‘successful’ expansions possibly related to the spread of Abashevo- and Battle Axe-related cultures (Indo-Iranian and Uralic alike).
R1a-M458 (formed ca. 2700, TMRCA ca. 2700 BC) appears mainly distributed to the north, from central Europe to the east – but not in the steppe in aDNA, with the most ‘successful’ expansions to the west.
M458 lineages seem thus to have expanded in the steppe in sizeable numbers only after the Iranian expansions (see a map of modern R1a distributions) i.e. possibly with the expansion of Slavs, which supports the model whereby cultures from central-east Europe (like Trzciniec and Lusatian), accompanied mainly by M458 lineages, were responsible for the expansion of Proto-Balto-Slavic (and later Proto-Slavic).
The finding of haplogroup R1a-Z93, among them one Z2123, is no surprise at this point after other similar Srubna samples. As I said, the early Srubna expansion is most likely responsible for the Szólád Bronze Age sample (ca. 2100-1700 BC), and for the Balkans BA sample (ca. 1750-1625 BC) from Merichleri, due to incursions along the central-east European steppe.
Cimmerian samples from the west show signs of continuity with R1a-Z93 lineages. Nevertheless, the sample of haplogroup Q1a-Y558, together with the ‘Pre-Scythian’ sample of haplogroup N (of the Mezőcsát Culture) in Hungary ca. 980-830 BC, as well as their PCA, seem to depict an origin of these Pre-Scythian peoples in populations related to the eastern Central Asian steppes, too.
NOTE. I will write more on different movements (unrelated to Uralic expansions) from Central and East Asia to the west accompanied by Siberian ancestry and haplogroup N with the post of Ugric-Samoyedic expansions.
The Scythian of Z2123 lineage ca. 375-203 BC from the Volga (in Mathieson et al. 2015), together with the sample scy193 from Glinoe (probably also R1a-Z2123), without a date, as well as their common Steppe_MLBA cluster, suggest that Scythians, too, were at first probably quite homogeneous as is common among pastoralist nomads, and came thus from the Central Asian steppes.
The reduction in haplogroup variability among East Iranian peoples seems supported by the three new Late Sarmatian samples of haplogroup R1a-Z2124.
Approximate location of Glinoe and Glinoe Sad (with Starosilya to the south, in Ukrainian territory):
This initial expansion of Scythians does not mean that one can dismiss the western samples as non-Scythians, though, because ‘Scythian’ is a cultural attribution, based on materials. Confirming the diversity among western Scythians, a session at the recent ISBA 8:
Genetic continuity in the western Eurasian Steppe broken not due to Scythian dominance, but rather at the transition to the Chernyakhov culture (Ostrogoths), by Järve et al.
The long-held archaeological view sees the Early Iron Age nomadic Scythians expanding west from their Altai region homeland across the Eurasian Steppe until they reached the Ponto-Caspian region north of the Black and Caspian Seas by around 2,900 BP. However, the migration theory has not found support from ancient DNA evidence, and it is still unclear how much of the Scythian dominance in the Eurasian Steppe was due to movements of people and how much reflected cultural diffusion and elite dominance. We present new whole-genome results of 31 ancient Western and Eastern Scythians as well as samples pre- and postdating them that allow us to set the Scythians in a temporal context by comparing the Western Scythians to samples before and after within the Ponto-Caspian region. We detect no significant contribution of the Scythians to the Early Iron Age Ponto-Caspian gene pool, inferring instead a genetic continuity in the western Eurasian Steppe that persisted from at least 4,800–4,400 cal BP to 2,700–2,100 cal BP (based on our radiocarbon dated samples), i.e. from the Yamnaya through the Scythian period.
(…) Our results (…) support the hypothesis that the Scythian dominance was cultural rather than achieved through population replacement.
Detail of the slide with admixture of Scythian groups in Ukraine:
The findings of those 31 samples seem to support what Krzewińska et al. (2018) found in a tiny region of Moldavia-south-western Ukraine (Glinoi, Glinoi Sad, and Starosilya).
The question, then, is as follows: if Scythian dominance was “cultural rather than achieved through population replacement”…Where are the R1b-Z2103 from? One possibility, as I said in the previous post, is that they represent pockets of Iranian R1b lineages in the steppes descended from eastern Yamna, given that this haplogroup appears in modern populations from a wide region surrounding the steppes.
The other possibility, which is what some have proposed since the publication of the paper, is that they are related to Thracians, and thus to Palaeo-Balkan populations. About the previously published Thracian individuals in Sikora et al. (2014):
For the Thracian individuals from Bulgaria, no clear pattern emerges. While P192-1 still shows the highest proportion of Sardinian ancestry, K8 more resembles the HG individuals, with a high fraction of Russian ancestry.
Despite their different geographic origins, both the Swedish farmer gok4 and the Thracian P192-1 closely resemble the Iceman in their relationship with Sardinians, making it unlikely that all three individuals were recent migrants from Sardinia. Furthermore, P192-1 is an Iron Age individual from well after the arrival of the first farmers in Southeastern Europe (more than 2,000 years after the Iceman and gok4), perhaps indicating genetic continuity with the early farmers in this region. The only non-HG individual not following this pattern is K8 from Bulgaria. Interestingly, this individual was excavated from an aristocratic inhumation burial containing rich grave goods, indicating a high social standing, as opposed to the other individual, who was found in a pit.
The following are excerpts from A Companion to Ancient Thrace (2015), by Valeva, Nankov, and Graninger (emphasis mine):
Thracian settlements from the 6th c. BC on:
(…) urban centers were established in northeastern Thrace, whose development was linked to the growth of road and communication networks along with related economic and distributive functions. The early establishment of markets/emporia along the Danube took place toward the middle of the first millennium BCE (Irimia 2006, 250–253; Stoyanov in press). The abundant data for intensive trade discovered at the Getic village in Satu Nou on the right bank of the Danube provides another example of an emporion that developed along the main artery of communication toward the interior of Thrace (Conovici 2000, 75–76).
Undoubtedly the most prominent manifestation of centralization processes and stratification in the settlement system of Thrace arrives with the emergence of political capitals – the leading urban centers of various Thracian political formations.
Their relationships with Scythians and Greeks
The Scythian presence south of the Danube must be balanced with a Thracian presence north of the river. We have observed Getae there in Alexander’s day, settled and raising grain. For Strabo the coastlands from the Danube delta north as far as the river and Greek city of Tyras were the Desert of the Getae (7.3.14), notable for its poverty and tracklessness beyond the great river. He seems to suggest also that it was here that Lysimachus was taken alive by Dromichaetes, king of the Getae, whose famous homily on poverty and imperialism only makes sense on the steppe beyond the river (7.3.8; cf. Diod. 21.12; further on Getic possessions above the Danube, Paus. 1.9 with Delev 2000, 393, who seems rather too skeptical; on poverty, cf. Ballesteros Pastor 2003). This was the kind of discourse more familiarly found among Scythians, proud and blunt in the strength of their poverty. However, as Herodotus makes clear, simple pastoralism was not the whole story as one advanced round into Scythia. For he observes the agriculture practiced north and west of Olbia. These were the lands of the Alizones and the people he calls the Scythian Ploughmen, not least to distinguish them from the Royal Scythians east of Olbia, in whose outlook, he says, these agriculturalist Scythians were their inferiors, their slaves (Hdt. 4.20). The key point here is that, as we began to see with the Getan grain-fields of Alexander’s day, there was scope for Thracian agriculturalists to maintain their lifestyles if they moved north of the Danube, the steppe notwithstanding. It is true that it is movement in the other direction that tends to catch the eye, but there are indications in the literary tradition and, especially, in the archaeological record that there was also significant movement northward from Thrace across the Danube and the Desert of the Getae beyond it.
Greek literary sources were not much concerned with Thracian migration into Scythia, but we should observe the occasional indications of that process in very different texts and contexts. At the level of myth, it is to be remembered that Amazons were regularly considered to be of Thracian ethnicity from Archaic times onward and so are often depicted in Thracian dress in Greek art (Bothmer 1957; cf. Sparkes 1997): while they are most familiar on the south coast of the Black Sea, east of Sinope, they were also located on the north coast, especially east of the Don (the ancient Tanais). Herodotus reports an origin-story of the Sauromatians there, according to which this people had been created by the union of some Scythian warriors with Amazons captured on the south coast and then washed up on the coast of Scythia (4.110). While the story is unhistorical, it is not without importance. First, it reminds us that passage north from the Danube was not the only way that Thracians, Thracian influence, and Thracian culture might find their way into Scythia. There were many more and less circuitous routes, especially by sea, that could bring Thrace into Scythia. Secondly, the myth offered some ideological basis for the Sauromatian settlement in Thrace that Strabo records, for Sauromatians might claim a Thracian origin through their Amazon forebears. Finally, rather as we saw that Heracles could bring together some of the peoples of the region, we should also observe that Ares, whose earthly home was located in Thrace by a strong Greek and Roman tradition, seems also to have been a deity of special significance and special cult among the Scythians. So much was appropriate, especially from a Classical perspective, in associations between these two peoples, whose fame resided especially in their capacity for war.
This broad picture of cultural contact, interaction, and osmosis, beyond simple conflict, provides the context for a range of archaeological discoveries, which – if examined separately – may seem to offer no more than a scatter of peculiarities. Here we must acknowledge especially the pioneering work of Melyukova, who has done most to develop thinking on Thracian–Scythian interaction. As she pointed out, we have a good example of Thracian–Scythian osmosis as early as the mid-seventh century bce at Tsarev Brod in northeastern Bulgaria, where a warrior’s burial combines elements of Scythian and Thracian culture (Melyukova 1965). For, while the manner of his burial and many of the grave goods find parallels in Scythia and not Thrace, there are also goods which would be odd in a Scythian burial and more at home in a Thracian one of this period (notably a Hallstatt vessel, an iron knife, and a gold diadem). Also interesting in this regard are several stone figures found in the Dobrudja which resemble very closely figures of this kind (baby) known from Scythia (Melyukova 1965, 37–38). They range in date from perhaps the sixth to the third centuries bce, and presumably were used there – as in Scythia – to mark the burials of leading Scythians deposited in the area. Is this cultural osmosis? We should probably expect osmosis to occur in tandem with the movement of artefacts, so that only good contexts can really answer such questions from case to case. However, the broad pattern is indicated by a range of factors. Particularly notable in this regard is the observable development of a Thraco-Scythian form of what is more familiar as “Scythian animal style,” a term which – it must be understood – already embraces a range of types as we examine the different examples of the style across the great expanse from Siberia to the western Ukraine. As Melyukova observes, Thrace shows both items made in this style among Scythians and, more numerous and more interesting, a Thracian tendency to adapt that style to local tastes, with observable regional distinctions within Thrace itself. Among the Getae and Odrysians the adaptation seems to have been at its height from the later fifth century to the mid-third century (Melyukova 1965, 38; 1979).
The absence of local animal style in Bulgaria before the fifth century bce confirms that we have cultural influences and osmosis at work here, though that is not to say that Scythian tradition somehow dominated its Thracian counterpart, as has been claimed (pace Melyukova 1965, 39; contrast Kitov 1980 and 1984). Of particular interest here is the horse-gear (forehead-covers, cheek-pieces, bridle fittings, and so on) which is found extensively in Romania and Bulgaria as well as in Scythia, both in hoarded deposits and in burials. This exemplifies the development of a regional animal style, not least in silver and bronze, which problematizes the whole issue of the place(s) of its production. Accordingly, the regular designation as “Thracian” of horse-gear from the rich fourth century Scythian burial of Oguz in the Ukraine becomes at least awkward and questionable (further, Fialko 1995). And let us be clear that this is no minor matter, nor even part of a broader debate about the shared development of toreutics among Thracians and Scythians (e.g., Kitov 1980 and 1984). A finely equipped horse of fine quality was a strong statement and striking display of wealth and the power it implied
(…) while Thracian pottery appears at Olbia, Scythian pottery among Thracians is largely confined to the eastern limits of what should probably be regarded as Getic territory, namely the area close to the west of the Dniester, from the sixth century bce. Rather exceptional then is the Scythian pottery noted at Istros, which has been explained as a consequence of the Scythian pursuit of the withdrawing army of Darius and, possibly, a continued Scythian grip on the southern Danube in its aftermath (Melyukova 1965, 34). The archaeology seems to show us, therefore, that the elite Thracians and Scythians were more open to adaptation and acculturation than were their lesser brethren.
(…) we see distinct peoples and organizations, for example as Sitalces’ forces line up against the Scythians. Much more striking, however, against that general background, are the various ways in which the two peoples and their elites are seen to interact, connect, and share a cultural interface. We see also in Scyles’ story how the Greek cities on the coast of Thrace and Scythia played a significant role in the workings of relationships between the two peoples. It is not simply that these cities straddled the Danube, but also that they could collaborate – witness the honors for Autocles, ca. 300 bce (SEG 49.1051; Ochotnikov 2006) – and were implicated with the interactions of the much greater non-Greek powers around them. At the same time, we have seen the limited reality of familiar distinctions between settled Thracians and nomadic Scythians and the limited role of the Danube too in dividing Thrace and Scythia. The interactions of the two were not simply matters of dynastic politics and the occasional shared taste for artefacts like horse-gear, but were more profoundly rooted in the economic matrix across the region, so that “Scythian” nomadism might flourish in the Dobrudja and “Thracian-style” agriculture and settlement can be traced from Thrace across the Danube as far as Olbia. All of that offers scant justification for the Greek tendency to run together Thracians and Scythians as much the same phenomenon, not least as irrational, ferocious, and rather vulgar barbarians (e.g., Plato, Rep. 435b), because such notions were the result of ignorance and chauvinism. However, Herodotus did not share those faults to any degree, so that we may take his ready movement from Scythians to Thracians to be an indication of the importance of interaction between the two peoples whom he had encountered not only as slaves in the Aegean world, but as powerful forces in their own lands (e.g., Hdt. 4.74, where Thracian usage is suddenly brought into his account of Scythian hemp). Similarly, Thucydides, who quite without need breaks off his disquisition on the Odrysians to remark upon political disunity among the Scythians (Thuc. 2.97, a favorite theme: cf. Hdt. 4.81; Xen., Cyr. 1.1.4). As we have seen throughout this discussion, there were many reasons why Thracians might turn the thoughts of serious writers to Scythians and vice versa.
It seems, following Sikora et al. (2014), that Thracian ‘common’ populations would have more Anatolian Neolithic ancestry compared to more ‘steppe-like’ samples. But there were important differences even between the two nearby samples published from Bulgaria, which may account for the close interaction between Scythians and Thracians we see in Krzewińska et al. (2018), potentially reflected in the differences between the Central, Southern and the South-Central clusters (possibly related to different periods rather than peoples??).
If these R1b-Z2103 were descended from Thracian elites, this would be the first proof of Palaeo-Balkan populations showing mainly R1b-Z2103, as I expect. Their appearance together with haplogroup I2a2a1b1 (also found in Ukraine Neolithic and in the Yamna outlier from Bulgaria) seem to support this regional continuity, and thus a long-lasting cultural and ethnic border roughly around the Danube, similar to the one found in the northern Caucasus.
However, since these samples are some 2,500 years younger than the Yamna expansion to the south, and they are archaeologically Scythians, it is impossible to say. In any case, it would seem that the main expansion of R1a-Z645 lineages to the south of the Danube – and therefore those found among modern Greeks – was mediated by the Slavic expansions centuries later.
On the Northern cluster there is a sample of haplogroup R1b-P312 which, given its position on the PCA (apparently even more ‘modern Celtic’-like than the Hallstatt_Bylany sample from Damgaard et al. 2018), it seems that it could be the product of the previous eastward Hallstatt expansion…although potentially also from a recent one?:
Especially important in the archaeology of this interior is the large settlement at Nemirov in the wooded steppe of the western Ukraine, where there has been considerable excavation. This settlement’s origins evidently owe nothing significant to Greek influence, though the early east Greek pottery there (from ca. 650 bce onward: Vakhtina 2007) and what seems to be a Greek graffito hint at its connections with the Greeks of the coast, especially at Olbia, which lay at the estuary of the River Bug on whose middle course the site was located (Braund 2008). The main interest of the site for the present discussion, however, is its demonstrable participation in the broader Hallstatt culture to its west and south (especially Smirnova 2001). Once we consider Nemirov and the forest steppe in connection with Olbia and the other locations across the forest steppe and coastal zone, together with the less obvious movements across the steppe itself, we have a large picture of multiple connectivities in which Thrace bulks large.
While the above description of clear-cut R1a-Steppe and R1b-Balkans is attractive (and probably more reliable than admixture found in scattered samples of unclear dates), the true ancient genetic picture is more complicated than that:
There is nothing in the material culture of the published western Scythians to distinguish the supposed Thracian elites.
We have the sample I0575, an Early Sarmatian from the southern Urals (one of the few available) of haplogroup R1b-Z2106, which supports the presence of R1b-Z2103 lineages among Eastern Iranian-speaking peoples.
We also have DA30, a Sarmatian of I2b lineage from the central steppes in Kazakhstan (ca. 47 BC – 24 AD).
Other Sarmatian samples of haplogroup R remain undefined.
There is R1a-Z93 in a late Sarmatian-Hun sample, which complicates the picture of late pastoralist nomads further.
Therefore, the possibility of hidden pockets of Iranian peoples of R1b-Z2103 (maybe also R1b-P312) lineages remains the best explanation, and should not be discarded simply because of the prevalent haplogroups among modern populations, or because of the different clusters found, or else we risk an obvious circular reasoning: “this sample is not (autosomically or in prevalent haplogroups) like those we already had from the steppe, ergo it is not from this or that steppe culture.” Hopefully, the upcoming paper by Järve et al. will help develop a clearer genetic transect of Iranian populations from the steppes.
All in all, the diversity among western Scythians represents probably one of the earliest difficult cases of acculturation to be studied with ancient DNA (obviously not the only one), since Scythians combine unclear archaeological data with limited and conflicting proto-historical accounts (also difficult to contrast with the wide confidence intervals of radiocarbon dates) with different evolving clusters and haplogroups – especially in border regions with strong and continued interactions of cultures and peoples.
With emerging complex cases like these during the Iron Age, I am happy to see that at least earlier expansions show clearer Y-DNA bottlenecks, or else genetics would only add more data to argue about potential cultural diffusion events, instead of solving questions about proto-language expansions once and for all…
This study included 321 samples from men throughout Corsica; samples from Provence and Tuscany were added to the cohort. All samples were typed for 92 Y-SNPs, and Y-STRs were also analyzed.
Haplogroup R represented approximately half of the lineages in both Corsican and Tuscan samples (respectively 51.8% and 45.3%) whereas it reached 90% in Provence. Sub-clade R1b1a1a2a1a2b-U152 predominated in North Corsica whereas R1b1a1a2a1a1-U106 was present in South Corsica. Both SNPs display clinal distributions of frequency variation in Europe, the U152 branch being most frequent in Switzerland, Italy, France and Western Poland. Calibrated branch lengths from whole Y chromosome sequencing [44,45] and ancient DNA studies  both indicated that R1a and R1b diversification began relatively recently, about 5 Kya, consistent with Bronze Age and Copper Age demographic expansion. TMRCA estimations are concordant with such expansion in Corsica.
Haplogroup G reached 21.7% in Corsica and 13.3% in Tuscany. Sub-clade G2a2a1a2-L91 accounted for 11.3% of all haplogroups in Corsica yet was not present in Provence or in Tuscany. Thirty-four out of the 37 G2a2a1a2-L91 displayed a unique Y-STR profile, illustrated by the star-like profile of STR networks (Fig 1). G2a2a1a2-L91 and G2a2a-PF3147(xL91xM286) show their highest frequency in present day Sardinia and southern Corsica compared to low levels from Caucasus to Southern Europe, encompassing the Near and Middle East [21,47–50]. Ancient DNA results from Early and Middle Neolithic samples reported the presence of haplogroup G2a-P15 [51–53], consistent with gene flow from the Mediterranean region during the Neolithic transition. Td expansion time estimated by STR for P15-affiliated chromosomes was estimated to be 15,082+/-2217 years ago . Ötzi, the 5,300-year-old Alpine mummy, was derived for the L91 SNP . A genetic relationship between G haplogroups from Corsica and Sardinia is further supported by DYS19 duplication, reported in North Sardinia , and observed in the southern part of the Corsica in 9 out of 37 G2a2a1a2-L91 chromosomes and in 4 out of 5 G2a2a-PF3147(xL91xM286) chromosomes, 3 of which displayed an identical STR profile (S4 Table).
This lineage has a reported coalescent age estimated by whole sequencing in Sardinian samples of about 9,000 years ago. This could reflect common ancestors coming from the Caucasus and moving westward during the Neolithic period , whereas their continental counterparts would have been replaced by rapidly expanding populations associated with the Bronze Age [46,54,55]. Estimated TMRCA for L91 lineage in Corsica is 4529 +/- 853 years. G-L497 showed high frequencies in Corsica compared to Provence and Tuscany, and this haplogroup was common in Europe, but rare in Greece, Anatolia and the Middle East. Fifteen out of the 17 Corsican G2a2b2a1a1b-L497 displayed a unique Y-STR profile (S4 Table) with an estimated TMRCA of 6867 +/- 1294 years. Haplogroup G2a2b1-M406, associated with Impressed Ware Neolithic markers, along with J2a1-DYS445 = 6 and J2a1b1-M92 [22,49], had very low levels in Corsica. Conversely, G2a2b2a-P303was highly represented and seemed to be independent of the G2a2b1-M406 marker. The 7 G2a2b2a-P303(xL497xM527) Corsican chromosomes displayed a unique Y-STR profile (S4 Table).
Haplogroup J, mainly represented by J2a1b-M67(xM92), displayed intermediate frequencies in Corsica compared to Tuscany and Provence. J2a1b-M67(xM92) derived STR network analysis displayed a quite homogeneous profile across the island with an estimated TMRCA of 2381 +/- 449 years (Fig 1) and individuals displaying M67 were peripheral compared to Northwestern Italians (S2 Fig). The haplogroup J2a1-Page55(xM67xM530), characteristic of non-Greek Anatolia , was found in the north-west of Corsica. Haplogroup J2a1-DYS445 = 6 was found in the north-west with DYS391 = 10 repeats, and in the far south with DYS391 = 9 repeats, the former was associated with Anatolian Greek samples, whereas the second was found in central Anatolia . The 7 J2b2a-M241 displayed a unique Y-STR profile (S4 Table), they were only detected in the Cap Corse region, this sub-haplogroup shows frequency peaks in both the southern Balkans and northern-central Italy  and is associated with expansion from the Near East to the Balkans during Neolithic period .
Haplogroup E, mainly represented by E1b1b1a1b1a-V13, displayed intermediate frequencies in Corsica compared to Tuscany and Provence. E1b1b1a1b1a-V13 was thought to have initiated a pan-Mediterranean expansion 7,000 years ago starting from the Balkans  and its dispersal to the northern shore of the Mediterranean basin is consistent with the Greek Anatolian expansion to the western Mediterranean , characteristic of the region surrounding Alaria, and consistent with the TMRCA estimated in Corsica for this haplogroup. A few E1b1a-V38 chromosomes are also observed in the same regions as V13.
In order to improve the phylogeography of the male-specific genetic traces of Greek and Phoenician colonizations on the Northern coasts of the Mediterranean, we performed a geographically structured sampling of seven subclades of haplogroup J in Turkey, Greece and Italy. We resequenced 4.4 Mb of Y-chromosome in 58 subjects, obtaining 1079 high quality variants. We did not find a preferential coalescence of Turkish samples to ancestral nodes, contradicting the simplistic idea of a dispersal and radiation of Hg J as a whole from the Middle East. Upon calibration with an ancient Hg J chromosome, we confirmed that signs of Holocenic Hg J radiations are subtle and date mainly to the Bronze Age. We pinpointed seven variants which could potentially unveil star clusters of sequences, indicative of local expansions. By directly genotyping these variants in Hg J carriers and complementing with published resequenced chromosomes (893 subjects), we provide strong temporal and distributional evidence for markers of the Greek settlement of Magna Graecia (J2a-L397) and Phoenician migrations (rs760148062). Our work generated a minimal but robust list of evolutionarily stable markers to elucidate the demographic dynamics and spatial domains of male-mediated movements across and around the Mediterranean, in the last 6,000 years.
Two features of our tree are at odds with the simplistic idea of a dispersal of Hg J as a whole from the Middle East towards Greece and Italy and an accompanying radiation26. First, there is little evidence of sudden diversification between 15 and 5 kya, a period of likely population increase and pressure for range expansion, due to the Agricultural revolution in the Fertile Crescent. Second, within each subclade, lineages currently sampled in Turkey do not show up as preferentially ancestral. Both findings are replicated and reinforced by examining the previous landmark studies. Our Turkish samples do not coalesce preferentially to ancestral nodes when mapped onto these studies’ trees.
Additional relevant information on the entire Hg J comes from the discontinuous distribution of J2b-M12. The northern fringe of our sample is enriched in the J2b-M241 subclade, which reappears in the gulf of Bengal38,45, with low frequencies in the intervening Iraq46 and Iran47. No J2b-M12 carriers were found among 35 modern Lebanese, as contrasted to one of two ancient specimens from the same region35.
In summary, a first conclusion of our sequencing effort and merge with available data is that the phylogeography of Hg J is complex and hardly explained by the presence of a single population harbouring the major lineages at the onset of agriculture and spreading westward. A unifying explanation for all the above inconsistencies could be a centre of initial radiation outside the area here sampled more densely, i.e. the Caucasus and regions North of it, from which different Hg J subclades may have later reached mainland Italy, Greece and Turkey, possibly following different routes and times. Evidence in this direction comes from the distribution of J2a-M41045,48 and the early-49 or mid-Holocene50 southward spread of J1.
The lineage defined by rs779180992, belonging to J2b-M205, and dated at 4–4.5 kya, has a radically different distribution, with derived alleles in Continental Italy, Greece and Northern Turkey, and two instances in a Palestinian and a Jew. The interpretation of the spread of this lineage is not straightforward. Tentative hypotheses are linked to Southward movements that occurred in the Balkan Peninsula from the Bronze Age29,53, through the Roman occupation and later54.
The slightly older (5.6–6.3 kya) branch 98 lineage displays a similar trend of a Eastward positioning of derived alleles, with the notable difference of being present in Sardinia, Crete, Cyprus and Northern Egypt. This feature and the low frequency of the parental J2a-M92 lineage in the Balkans27 calls for an explanation different from the above.
Finally, we explored the distribution of J2a-L397 and three derived lineages within it. J2a-L397 is tightly associated with a typical DYS445 6-repeat allele. This has been hypothesized as a marker of the Greek colonizations in the Mediterranean55, based on its presence in Greek Anatolia and Provence (France), a region with attested Iron Age Greek contribution. All of our chromosomes in this clade were characterized also by DYS391(9), confirming their Anatolian Greek signature. We resolved the J2a-L397 clade to an unprecedented precision, with three internal markers which allow a finer discrimination than STRs. The ages of the three lineages (2.0–3.0 kya) are compatible with the beginning of the Greek colonial period, in the 8th century BCE. The three subclades have different distributions (Fig. 2B), with two (branches 57, 59) found both East and West to Greece, and one only in Italy (branch 58). As to Mediterranean Islands, J2a-L397 was found in Cyprus56 and Crete43. Its presence as one of the three branches 57–59 will represent an important test. In Italy all three variants were found mainly along the Western coast (18/25), which hosted the preferred Greek trade cities. The finding of all three differentiated lineages in Locri excludes a local founder effect of a single genealogy. Interestingly, an important Greek colony was established in this location, with continuity of human settlement until modern times. The sample composed of the same subjects displayed genetic affinities with Eastern Greece and the Aegean also at autosomal markers57. In summary, the distributions of branches 57–59 mirror the variety of the cities of origin and geographic ranges during the phases of the colonization process58.
So, there you have it, another proof that haplogroup J and CHG-related ancestry in the Mediterranean was mainly driven by different (and late) expansions of historic peoples.
Assessing population diversity in southern Italy has traditionally relied on archaeological and historic evidence. Although informative, these lines of evidence do not establish specific instances of within lifetime mobility, nor track population diversity over time. In order to investigate the population structure of ancient South Italy I sequenced the mitochondrial DNA (mtDNA) from 15 Iron Age (7th – 4th c. BCE) and 30 Roman period (1st – 4th c. BCE) individuals buried at Iron Age Botromagno and Roman period Vagnari, in southern Italy, and analyzed δ18O and 87Sr/86Sr values from a subset of the Vagnari skeletal assemblage.
Phylogenetic analysis of 15 Iron Age mtDNAs together with 231 mtDNAs spanning European prehistory suggest that southern Italian Iapygians share close genetic affinities to Neolithic populations from eastern Europe and the Near East. Population pairwise analysis of Iron Age, Roman, and mtDNA datasets spanning the pan-Mediterranean region (n=357), indicate that Roman maternal genetic diversity is more similar to Neolithic and Bronze Age populations from central Europe and the eastern Mediterranean, respectively, than to Iron Age Italians. Genetic distance between population age categories imply moderate mtDNA turnover and constant population size during the Roman conquest of South Italy in the 3rd century BCE.
In order to determine the local versus non-local demographic at Vagnari, I measured the 87Sr/86Sr and 18O/16O of composition of 43 molars, and the 87Sr/86Sr composition of an additional 13 molars, and constructed a preliminary 87Sr/86Sr variation map of the Italian peninsula using disparate 87Sr/86Sr datasets. The relationship between 87Sr/86Sr and previously published δ18O data suggest a relatively low proportion of migrants lived at Vagnari (7%).
This research is the first to generate whole-mitochondrial DNA sequences from Iron Age and Roman period necropoleis, and demonstrates the ability to gain valuable information from the integration of aDNA, stable isotope, archaeological and historic evidence.
Taken together, population pairwise ΦST, and the distribution of mtDNA haplotypes in relation to the comparative mtDNA data set show that the Iron Age southern Italians likely descended from early to late Neolithic farmers from Anatolia and possibly as far East as the Caucasus, and from migrants arriving from eastern Europe around the late Neolithic/early Bronze Age. These findings support previous hypotheses that the ancestors of the Iapygians may have originated in the eastern Balkan region, or derive shared ancestry with a common source population from eastern Europe. Alternatively, southern Italian Iron Age mtDNA variation might also reflect LGM gene flow between southwestern European, Mediterranean, and Carpathian basin refugia, which was suggested for haplogroup subclusters of U5 and J (Malyarchuk et al., 2010; Pala et al., 2012). Future mtDNA (and nuclear DNA) analysis comprised of a larger Iron Age data set from southern Italy is necessary to answer Theodor Mommsen’s initial hypothesis that the Iapygians were the oldest immigrants to the southern Italian region.
Our investigation provides the first mtDNA evidence for the maternal ancestral affiliations of a subset of the Iapygian individuals recovered from southern Italy, and suggests a closer genetic link to European Neolithic and Iron Age Armenians, than to Bronze Age Aegeans. Future comparative ancient DNA data using whole-genome SNP, mtDNA, and NRY-chromosome analysis of pre-Roman populations will provide complementary evidence for the ancestral roots of understudied Iron Age individuals from Italy.
Archaeological evidence indicates that the Iapygians traded and incorporated Hellenistic elements into their material and cultural traditions (Small, 1992; Peruzzi, 2016). These changes are most apparent in burial custom and ceramic production, and become increasingly prominent by 2400 BP (Peruzzi, 2016). Further evidence shows that Iron Age communities across South Italy retracted in size amidst ongoing conflict between colonies in Magna Graecia, and Rome and Carthage (Small, 1992). This apparent change was interpreted as a decline in local populations throughout the region. However, Bayesian Skygrid analysis using the mtDNA profiles of 15 Iapygians and 30 Roman period individuals suggest that female effective population size was comparable between the two populations. In Chapter 4, population distance (measured as population pairwise ΦST values) across a range of mtDNAs obtained from the pan-Mediterranean, European, and western Asian regions suggest closer maternal affinities to Neolithic and Bronze Age populations from the eastern Mediterranean as a cohort, than with Iron Age Italians. This finding points to moderate mtDNA turnover, and is likely the consequence of Roman gene flow stemming from central and northern Italy via the migration and subsequent occupation by Roman colonies after 2250 BP.
Roman Imperial pursuits peaked by ~2050 BP. This extension of power, coupled with an increase in food and materials procurement, was driven by a substantial labour force comprised of both low status Romans and slaves (Harris, 1980; Bradley, 1987, 1994, 2000). Although several attempts have been made to quantify the number of slaves required to maintain the Roman economy, it is unknown what fraction of the Roman population was slave-owned (~approximately 1 to 3 million by 2050 BP) (Scheidel, 2005). Rome’s slave acquisition during the early centuries of the Republic was likely maintained through military campaigns and conquest, a trend that is well documented in Italy (Scheidel, 1997, 1999, 2005; Harris, 1999; Small, 2002). However, once territory was secured, local slave populations were likely maintained through one or a combination of the following: i) the importation of slaves from non-local regions, ii) were born to slave-owned parents, or iii) were voluntarily self-enslaved to acquire subsistence (Harris, 1999). The importation of foreign slaves was likely more costly than maintaining a self-reproducing slave population, especially in rural areas. As such, rural Roman necropoleis, such Vagnari, provide an opportune case to determine the local versus non-local demographic. Archaeological evidence suggests that Vagnari was involved in agriculture and industrial procurement, and was likely staffed by low-class individuals possibly including slaves (Small et al., 2000). However, without direct archaeological or epigraphic evidence, it is impossible to identify the proportion of slaves at rural sites.
(…) The isotope values presented in Chapter 3 obtained from 56 Roman individuals buried at Vagnari suggest that over half (58%) were born directly at Vagnari, with a further 34% originating from South Italy. Only 7% (3/43 with both δ18O and 87Sr/86Sr values) of the individuals sampled resulted in isotope values non-local to the southern peninsula. Two of these individuals originated from either northern Italy or, more broadly, from central Europe, while one individual likely originated from North Africa. Overall, the isotope data suggest a low number of immigrants at Vagnari, which conforms with the population pairwise (ΦST) data for the Iron Age and Roman mtDNAs, and suggests that as the Romans occupied the region, they populated their Imperial properties with people from central Italy (possible the region of Latium, and the surrounding environs of Rome). These results also integrate with the historical evidence concerning the Roman slave economy during the Imperial period. Future research using a larger comparative dataset comprised of pre-Roman and Roman period mtDNAs, δ18O and, 87Sr/86Sr results will refine the interpretations outlined here.
This paper is a comparative study based on the linguistic evidence in Vedic Sanskrit and Homeric Greek, aimed at reconstructing the space-time cognitive models used in the Proto-Indo-European language in a diachronic perspective. While it has been widely recognized that ancient Indo-European languages construed earlier (and past) events as in front of later ones, as predicted in the Time-Reference-Point mapping, it is less clear how in the same languages the passage took place from this ‘archaic’ Time-RP model or non-deictic sequence, in which future events are behind or follow the past ones in a temporal sequence, to the more recent ‘post-archaic’ Ego-RP model that is found only from the classical period onwards, in which the future is located in front and the past in back of a deictic observer. Data from the Rigveda and the Homeric poems show that an Ego-RP mapping with an ego-perspective frame of reference (FoR) could not have existed yet at an early Indo-European stage. In particular, spatial terms of front and behind turn out to be used with reference not only to temporal events, but also to east and west respectively, thus presupposing the existence of an absolute field-based FoR which the temporal sequence is metaphorically related to. Specifically, sequence is relative position on a path appears to be motivated by what has been called day orientation frame, in which the different positions of the sun during the day motivate the mapping of front onto ‘earlier’ and behind onto ‘later’, without involving ego’s ‘now’. These findings suggest that early Indo-European still had not made use of spatio-temporal deixis based on the tense-related ego-perspective FoR found in modern languages.
Featured image, from the article: Helios rising from the sea (blacas red-figured calyx-krater, fifth century B.C., British Museum). Related quote from the article: “Interestingly, the archeological evidence supports that time could be spatialized along the lateral axis. In ancient Greek art the sun is represented as moving from right to left. Such orientation can be observed, for instance, on the Blacas red-figured calyx-krater of the fifth century B.C. (London, British Museum), where Helios is found at the extreme right of the scene and proceeds to the viewer’s left, following Eos, i.e., the dawn.”
The recording is available as audio (see above) or video (see below) with captions and multiple subtitles. The captions in North-West Indo-European show acute accents over accented vowels, while stressed syllables are underlined:
I think such a recording was necessary for comparison with the most commonly reconstructed pronunciation, as taught usually in courses. And I am not referring to those professors still using only stress – instead of pitch – accent to pronounce PIE, but to those that, using pitch accent, do place stress over the same syllable.
Apart from some controversial decisions regarding the Proto-Indo-Hittite reconstruction – see our explanation of our version, or e.g. Kortlandt’s reconstruction of the Fable (PDF) for more details – , his recitation does not seem to contrast enough pitch and stress accent, to the extent that pitch and stress seem to be always on the same syllable. He specialises in Proto-Indo-European phonology, so maybe it is a voluntary selection.
Firstly, as an introduction – in case you don’t know anything about this question -, a pitch accent is reconstructed for Proto-Indo-European, based on the reconstructed accent of Old Indian, Greek, Germanic, and Balto-Slavic – hence also valid for North-West Indo-European, even though Italo-Celtic lost it completely.
If you have listened to any tonal language*, words have also stress accent, and not necessarily on the same syllable – but usually on the heaviest one. In fact, I don’t know of an accent pattern with pitch+stress on the same syllable (but for certain reconstructed intermediate labile stages of a languages), and I guess it is so redundant that it would always lose one of them.
*pitch-accent systems are also tonal systems, after all, since they involve at least two tones: an acute or rising one, and usually a falling one after it.
You can listen to a sample of the Homeric recitation by Stephen Daitz, with restored Ancient Greek pronunciation, where he contrasts pitch and stress beautifully:
To see what I mean with the lack of contrast in Byrd’s pronunciation, just compare the restored pronunciation with these samples, of restored Koine Greek, from the Biblical Language Center. I think you can hear pitch accent pronounced, but always stressing the same syllable. After a while, it gets quite monotone (no pun intended); for me, at least*.
Pitch accent in my pronunciation is not as noticeable as that of Stephen Daitz, and still less than that of Stefan Hagel. But it is not intended to.
I wanted to combine tone and stress as naturally as possible, as it is found in modern languages, like Chinese, or like South Slavic, Baltic, or Scandinavian languages. I believe PIE phonology cannot be too different from modern natural examples.
Many Modern Greek scholars complain about the artificiality of the restored pronunciation. I’ve heard particularly harsh criticism against Stefan Hagel’s pronunciation: many scholars do not recognise the ancestral language in the restored pronunciation.
While such critics may seem like snob reactionaries, and I really appreciate an exaggerated poetic style for epic poems (I have spent hundreds, probably thousands, of hours listening to Stephen Daitz), I don’t think this is the way Ancient Greek was usually spoken. Listening to Hagel’s pronunciation in the Ancient Greek Assimil, there is a huge contrast between readers who don’t use the restored pronunciation in the recordings (offering thus a decaffeinated Ancient Greek), and Hagel’s reading (or, almost, singing).
In my interpretation of the fable I have tried to follow these ideas, and maybe in the end the pitch accent is not as acute as it should be (a fifth higher). On the other hand, it seemed more natural to me this way.
Also, in the final version of my reading, there are many words where it is not clear – not even to me – if there is more than one syllable with pitch or stress accent. This is especially so after after my first change of voice to make a more acute ‘sheep voice’, and then worsens with my graver ‘horse voice’. I really thought recording this was going to be easier!
If you have any comments or suggestions on the pronunciation, they are all welcome.
UPDATE (November 2, 2017): Frederik Kortlandt comments our paper – “When comparing PIE with other tonal languages, the best candidate is Japanese, which means that the “stress” falls on the last High syllable of a word form or sequence of connected word forms.”
The origins of the Bronze Age Minoan and Mycenaean cultures have puzzled archaeologists for more than a century. We have assembled genome-wide data from 19 ancient individuals, including Minoans from Crete, Mycenaeans from mainland Greece, and their eastern neighbours from southwestern Anatolia. Here we show that Minoans and Mycenaeans were genetically similar, having at least three-quarters of their ancestry from the first Neolithic farmers of western Anatolia and the Aegean, and most of the remainder from ancient populations related to those of the Caucasus3 and Iran. However, the Mycenaeans differed from Minoans in deriving additional ancestry from an ultimate source related to the hunter–gatherers of eastern Europe and Siberia, introduced via a proximal source related to the inhabitants of either the Eurasian steppe or Armenia. Modern Greeks resemble the Mycenaeans, but with some additional dilution of the Early Neolithic ancestry. Our results support the idea of continuity but not isolation in the history of populations of the Aegean, before and after the time of its earliest civilizations.
Regarding admixture analyses, it is explicitly or implicitly (according to the press release) stated that:
There is continuity between Mycenaeans and living people, so that the major components of the Greeks’ ancestry was in place already in the Bronze Age, after the migration of the earliest farmers from Anatolia.
Anatolians may have been the source of “eastern” Caucasian ancestry in Mycenaeans, and maybe of early Indo-European languages (i.e. earlier than Proto-Greek) in the region.
The “northern” steppe population (speaking a Late Indo-European dialect, then) had arrived only in mainland Greece, with a 13-18% admixture, by the time studied.
Samples before the Final Neolithic (ca. 4100 BC) do not possess either type of ancestry, suggesting that the admixture detected occurred during the fourth to second millennium BC.
Admixture from Levantine or African influence (i.e. Egyptian or Phoenician colonists) cannot be supported with admixture.
All in all, there is some new interesting information, and among them the possibility of obtaining ancient DNA from arid regions, which is promising for future developments in the field.
EDIT (20/8/2017): The article received widespread media attention, and two blog posts were linked to by the main author in his Twitter account: Who are you calling Mycenaean?, and On genetics and the Aegean Bronze Age. Apart from the obviously wrong reductio ad Hitlerum that pops up in any discussion on Indo-Europeans or genetics (even I do it regarding fans of admixture analysis), I don’t know why these created so much fuss (and hate) among geneticists. There seems to be a war brewing between Archaeology and Genetics.
