Prehistoric loan relations: Foreign elements in the Proto-Indo-European vocabulary

ancient-indo-european-world-fantasy

An interesting ongoing web project, Prehistoric loan relations, on potential loans of Proto-Indo-European words, from Uralic-Yukaghir, Caucasian, and Middle Eastern influence.

Based on a Ph.D. thesis by Bjørn (2017) Foreign elements in the Proto-Indo-European vocabulary (PDF).

From the website (emphasis mine):

This page allows historical linguists to compare and scrutinize proposed prehistoric lexical borrowings from the perspective of Proto-Indo-European. The first entries are all (135 in total) extracted from my master’s thesis “Foreign elements in the Proto-Indo-European vocabulary” (Bjørn 2017). Comments are encouraged at the bottom of each entry. New entries will be added, also on request.

Take this not as the conclusion, but an invitation to join the conversation.

So, we welcome the invitation, and hope that this new project thrives.

Also, I loved his fantasy-like map of the central Eurasian region (featured image on this post).

Expansion of peoples associated with spread of haplogroups: Mongols and C3*-F3918, Arabs and E-M183 (M81)

iron-age-migrations

Two recent interesting papers on the potential expansion of cultures associated with haplogroups:

1. Whole Y-chromosome sequences reveal an extremely recent origin of the most common North African paternal lineage E-M183 (M81), by Solé-Morata et al., Scientific Reports (2017).

Abstract:

E-M183 (E-M81) is the most frequent paternal lineage in North Africa and thus it must be considered to explore past historical and demographical processes. Here, by using whole Y chromosome sequences from 32 North African individuals, we have identified five new branches within E-M183. The validation of these variants in more than 200 North African samples, from which we also have information of 13 Y-STRs, has revealed a strong resemblance among E-M183 Y-STR haplotypes that pointed to a rapid expansion of this haplogroup. Moreover, for the first time, by using both SNP and STR data, we have provided updated estimates of the times-to-the-most-recent-common-ancestor (TMRCA) for E-M183, which evidenced an extremely recent origin of this haplogroup (2,000–3,000 ya). Our results also showed a lack of population structure within the E-M183 branch, which could be explained by the recent and rapid expansion of this haplogroup. In spite of a reduction in STR heterozygosity towards the West, which would point to an origin in the Near East, ancient DNA evidence together with our TMRCA estimates point to a local origin of E-M183 in NW Africa.

An interesting excerpt, from the discussion:

Regarding the geographical origin of E-M183, a previous study suggested that an expansion from the Near East could explain the observed east-west cline of genetic variation that extends into the Near East. Indeed, our results also showed a reduction in STR heterozygosity towards the West, which may be taken to support the hypothesis of an expansion from the Near East. In addition, previous studies based on genome-wide SNPs reported that a North African autochthonous component increase towards the West whereas the Near Eastern decreases towards the same direction, which again support an expansion from the Near East. However, our correlations should be taken carefully because our analysis includes only six locations on the longitudinal axis, none from the Near East. As a result, we do not have sufficient statistical power to confirm a Near Eastern origin. In addition, rather than showing a west-to-east cline of genetic diversity, the overall picture shown by this correlation analysis evidences just low genetic diversity in Western Sahara, which indeed could be also caused by the small sample size (n = 26) in this region. Alternatively, given the high frequency of E-M183 in the Maghreb, a local origin of E-M183 in NW Africa could be envisaged, which would fit the clear pattern of longitudinal isolation by distance reported in genome-wide studies. Moreover, the presence of autochthonous North African E-M81 lineages in the indigenous population of the Canary Islands, strongly points to North Africa as the most probable origin of the Guanche ancestors. This, together with the fact that the oldest indigenous inviduals have been dated 2210 ± 60 ya, supports a local origin of E-M183 in NW Africa. Within this scenario, it is also worth to mention that the paternal lineage of an early Neolithic Moroccan individual appeared to be distantly related to the typically North African E-M81 haplogroup30, suggesting again a NW African origin of E-M183. A local origin of E-M183 in NW Africa > 2200 ya is supported by our TMRCA estimates, which can be taken as 2,000–3,000, depending on the data, methods, and mutation rates used.

The TMRCA estimates of a certain haplogroup and its subbranches provide some constraints on the times of their origin and spread. Although our time estimates for E-M78 are slightly different depending on the mutation rate used, their confidence intervals overlap and the dates obtained are in agreement with those obtained by Trombetta et al Regarding E-M183, as mentioned above, we cannot discard an expansion from the Near East and, if so, according to our time estimates, it could have been brought by the Islamic expansion on the 7th century, but definitely not with the Neolithic expansion, which appeared in NW Africa ~7400 BP and may have featured a strong Epipaleolithic persistence. Moreover, such a recent appearance of E-M183 in NW Africa would fit with the patterns observed in the rest of the genome, where an extensive, male-biased Near Eastern admixture event is registered ~1300 ya, coincidental with the Arab expansion. An alternative hypothesis would involve that E-M183 was originated somewhere in Northwest Africa and then spread through all the region. Our time estimates for the origin of this haplogroup overlap with the end of the third Punic War (146 BCE), when Carthage (in current Tunisia) was defeated and destroyed, which marked the beginning of Roman hegemony of the Mediterranean Sea. About 2,000 ya North Africa was one of the wealthiest Roman provinces and E-M183 may have experienced the resulting population growth.

2. The Y-chromosome haplogroup C3*-F3918, likely attributed to the Mongol Empire, can be traced to a 2500-year-old nomadic group, by Zhang et al., Journal of Human Genetics (2017)

Abstract:

The Mongol Empire had a significant role in shaping the landscape of modern populations. Many populations living in Eurasia may have been the product of population mixture between ancient Mongolians and natives following the expansion of Mongol Empire. Geneticists have found that most of these populations carried the Y-haplogroup C3* (C-M217). To trace the history of haplogroup (Hg) C3* and to further understand the origin and development of Mongolians, ancient human remains from the Jinggouzi, Chenwugou and Gangga archaeological sites, which belonged to the Donghu, Xianbei and Shiwei, respectively, were analysed. Our results show that nine of the eleven males of the Gangga site, two of the eight males of Chengwugou site and all of the twelve males of Jinggouzi site were found to have mutations at M130 (Hg C), M217 (Hg C3), L1373 (C2b, ISOGG2015), with the absence of mutations at M93 (Hg C3a), P39 (Hg C3b), M48 (Hg C3c), M407 (Hg C3d) and P62 (Hg C3f). These samples were attributed to the Y-chromosome Hg C3* (Hg C2b, ISOGG2015), and most of them were further typed as Hg C2b1a based on the mutation at F3918. Finally, we inferred that the Y-chromosome Hg C3*-F3918 can trace its origins to the Donghu ancient nomadic group.

The expansion of peoples is known to be associated with the spread of a certain admixture component, joint with the expansion and reduction in variability of a haplogroup. In other words, few male lineages are usually more successful during the expansion.

Human ancestry solves language questions? New admixture citebait

human_ancestry

A paper at Scientific Reports, Human ancestry correlates with language and reveals that race is not an objective genomic classifier, by Baker, Rotimi, and Shriner (2017).

Abstract (emphasis mine):

Genetic and archaeological studies have established a sub-Saharan African origin for anatomically modern humans with subsequent migrations out of Africa. Using the largest multi-locus data set known to date, we investigated genetic differentiation of early modern humans, human admixture and migration events, and relationships among ancestries and language groups. We compiled publicly available genome-wide genotype data on 5,966 individuals from 282 global samples, representing 30 primary language families. The best evidence supports 21 ancestries that delineate genetic structure of present-day human populations. Independent of self-identified ethno-linguistic labels, the vast majority (97.3%) of individuals have mixed ancestry, with evidence of multiple ancestries in 96.8% of samples and on all continents. The data indicate that continents, ethno-linguistic groups, races, ethnicities, and individuals all show substantial ancestral heterogeneity. We estimated correlation coefficients ranging from 0.522 to 0.962 between ancestries and language families or branches. Ancestry data support the grouping of Kwadi-Khoe, Kx’a, and Tuu languages, support the exclusion of Omotic languages from the Afroasiatic language family, and do not support the proposed Dené-Yeniseian language family as a genetically valid grouping. Ancestry data yield insight into a deeper past than linguistic data can, while linguistic data provide clarity to ancestry data.

Regarding European ancestry:

Southern European ancestry correlates with both Italic and Basque speakers (r = 0.764, p = 6.34 × 10−49). Northern European ancestry correlates with Germanic and Balto-Slavic branches of the Indo-European language family as well as Finno-Ugric and Mordvinic languages of the Uralic family (r = 0.672, p = 4.67 × 10−34). Italic, Germanic, and Balto-Slavic are all branches of the Indo-European language family, while the correlation with languages of the Uralic family is consistent with an ancient migration event from Northern Asia into Northern Europe. Kalash ancestry is widely spread but is the majority ancestry only in the Kalash people (Table S3). The Kalasha language is classified within the Indo-Iranian branch of the Indo-European language family.

Sure, admixture analysis came to save the day. Yet again. Now it’s not just Archaeology related to language anymore, it’s Linguistics; all modern languages and their classification, no less. Because why the hell not? Why would anyone study languages, history, archaeology, etc. when you can run certain algorithms on free datasets of modern populations to explain everything?

What I am criticising here, as always, is not the study per se, its methods (PCA, the use of Admixture or any other tools), or its results, which might be quite interesting – even regarding the origin or position of certain languages (or more precisely their speakers) within their linguistic groups; it’s the many broad, unsupported, striking conclusions (read the article if you want to see more wishful thinking).

This is obviously simplistic citebait – that benefits only journals and authors, and it is therefore tacitly encouraged -, but not knowledge, because it is not supported by any linguistic or archaeological data or expertise.

Is anyone with a minimum knowledge of languages, or general anthropology, actually reviewing these articles?

C.C. Uhlenbeck on the Proto-Indo-European homeland in the 19th century

yamna-expansion-europe

Michiel de Vaan, from the University of Lausanne, has recently uploaded three of his papers published in recent years in the JIES on the works of Dutch linguist C.C. Uhlenbeck:

1. The Early C. C. Uhlenbeck on Indo-European, JIES 44/1-2, 2016, p. 73-80

Christianus Cornelius Uhlenbeck (1866–1951) was one of the leading Dutch linguists between the 1880s and the 1940s. He made his mark on a number of disciplines in descriptive and comparative linguistics, such as Basque, the indigenous languages of North America, Old Germanic and Sanskrit. In 2008, a special issue of the Canadian Journal of Netherlandic Studies (Genee & Hinrichs 2008) was devoted to his memory, the contents of which can be read online.

Uhlenbeck’s work and thinking on the Indo-European language family, and, in particular, on the original habitat of its speakers, have been discussed by Kortlandt 2010, who concluded that Uhlenbeck had remarkably advanced views for his time. The first two journal articles in which Uhlenbeck (1895, 1897) sets forth his views were published in Dutch. During the academic year 2013/14, I had the opportunity to read a number of articles on the question of the Indo-European homeland problem with my students at Leiden University. I provided Uhlenbeck’s Dutch articles from 1895 and 1897 with an English translation which I hereby submit to all colleagues

On Anthony and Haarman:

Anthony focuses on the socioeconomic changes that took place in the fifth and fourth millennium BC, when the Indo-European steppe peoples entered into contact with the sedentary, agricultural population of Southeast-Europe, also termed Old European or Palaeo-European. Importantly, Anthony dismantles the monolithic view of a single “steppe pastoralism”, and instead stresses that the steppe economy itself went through various developmental phases, which might be linked to different periods of expansion of Indo-European into Europe. Haarmann zooms in on the sociocultural effects of the Indo-European expansion(s). Since language contact will often heavily influence the languages which are in contact, he sets out to look for traces of the language of the Old Europeans in the surviving Indo-European languages, first of all, in Ancient Greek. As many scholars before him have also realized, there is a thick layer of non-Indo-European words in Greek in fields such as agriculture, wine production, weaving, metallurgy, religion and mythology, building techniques, and local flora and fauna. Even the Greeks themselves acknowledged the presence of a “Pelasgian” substratum in their own language. Haarmann concludes (2012: 119): “Despite the fact that Indo-Europeans exercised political power and promoted their language as the common vehicle, they were nevertheless impressed by the achievements of the Old Europeans to the extent that the dominant language of the élite absorbed manifold influences from the local language(s).”

2. Where was the Indo-European proto-language spoken?, by C.C. Uhlenbeck (1895), translation by Michiel de Vaan, JIES 44/1-2, 2016, p. 181-185.

It cannot be objected that the eastern and the western Iranians differed much in their dialects, for the PIE language itself must have been split in a number of fairly different dialects. There has never been in the world a language without dialect differences, larger or smaller, depending on the geographic distance. That is why, in the beginning of this piece, I spoke not of one original language, but of a group of closely cognate dialects. Since the linguistic area of PIE was probably very large, it is certainly possible that part of it lay in the steppes, another part in the mountains, and yet another part in the fertile plains. If so, the fauna and the flora of the homeland cannot have been the same in different areas. And this is an argument, which the linguistic prehistorician must not lose sight of!

On the necessary natural (geographic and stage) division of PIE, he made apparently a dialectal division into a European group (including Greek?), a Balkan-Balto-Slavic group, and Indo-Iranian.

3. The prehistory of the Indo-European peoples, by C.C. Uhlenbeck (1897), translation by Michiel de Vaan, JIES 44/1-2, 2016, 186-212.

The following excerpt is probably not the most interesting one (check out the different aspect of prehistoric life described through linguistics), but it is fun to be able to support the same arguments today:

Does linguistics provide us with the means to indicate a smaller region as the center of expansion of the Indo-European languages and peoples? Hardly. After all, it is far from certain that the people who speak Indo-European languages are also ethnologically more closely related to each other than to peoples with languages very different from ours. If the homeland of the Indo-European languages does not coincide with that of the Indo-European peoples, it becomes impossible to determine either one. In reality, if the Indo-European speaking peoples do not form an ethnological unity, we have not the slightest reason to suppose that they all hail from a single region. The use of a common language can just as well be explained by a powerful, prehistoric cultural influence, as by common ancestry. The unknown, unknowable origin of that cultural force is then, in a certain sense, the homeland of our language family. Searching a homeland of the Indo-Europeans or of the Indo-European dialects is like taking a wild stab, something which all who understand history must abhor. If Schrader regards as the homeland the Pontic steppes, if Hirt regards the coasts of Lithuania as such, this is based on insufficient and partially judged data. Still, the large agreement in vocabulary between Indo-European and Egypto-Semitic remains a remarkable fact, which Friedrich Delitzsch first illustrated in a truly scientific way.

(…)

If we stick to the facts, and refrain from bottomless speculations, we will find no other homeland than the area indicated above, which encompasses half of Europe and a part of Asia.

Potential Afroasiatic Urheimat near Lake Megachad

palaeolithic-migrations

The publication of new ancient DNA samples from Africa is near, according to people at the SMBE meeting. As reported by Anthropology.net, a group by Pontus Skoglund has analysed new samples (complementing the study made by Carina Schlebusch), so we will have ancient samples of Africans from 300 to 6,000 years ago. They have been compared to the data of modern African populations, and among their likely conclusions (to be published):

  • Several thousand years ago, likely Tanzanian herders migrated far and wide, reaching Southern Africa centuries before the first farmers.
  • West Africans were likely early contributors to the gene pool of sub-Saharan Africans.
  • One ancient African herder showed influence from even farther abroad, with 38% of their DNA coming from outside Africa. 9-22% of the DNA of modern farmers, including the southern Khoe-San, comes from East Africans and Eurasian herders
  • Modern farmers, the ones as old as 500 years old, did have Bantu DNA in their genomes, but the ancient hunter-gatherers predated the spread of the Bantu.

Razib Khan, asked about the Afroasiatic homeland by David Reich, has taken this opportunity to publish his own hypothesis on the expansion of Afroasiatic, given the known Admixture analyses, using Y-DNA phylogeography, and with reasonable assumptions. He concludes that Afroasiatic expansion might also be associated with the western expansion of E1b1b subclades from a Levantine (“Natufian”) homeland.

I think it is necessary to remind everyone of the many problems unsolved by Indo-European studies – a much older discipline (and with more research published) than Afroasiatic studies. It is already quite revealing that we can’t still trace back Proto-Semitic to its homeland, and that Proto-Semitic is probably as old as Late Proto-Indo-European. We are talking, then, about an ancient proto-language – Afroasiatic – possibly older than Middle Indo-European (or Indo-Hittite), and whose dialects are still not well studied – but for the Semitic and Egyptian branches. Linguistic guesstimates or phylogenetic speculation date the proto-language (and thus the homeland) within a wide range, from 15,000 to 6,000 years ago.

There is an obvious trend (probably driven by Semitic and Egyptian researchers) to place the Afroasiatic Homeland near one of the many proposed Semitic homelands, i.e. in East Africa. This is similar to the trend seen in the first half of the 20th century in Indo-European studies, with most proposals locating the Proto-Indo-European homeland in Europe. European languages were the best known, and only the perceived antiquity of Vedic Sanskrit made some propose South Asian origins for the proto-language. However, it was only careful interpretation of linguistic finds, combined with archaeological data, what eventually yielded the Kurgan hypothesis, which has been since refined.

afroasiatic-homeland
A model for the homeland and expansion of Afroasiatic, from Wikipedia

Razib Khan’s proposal makes sense in that it fits what others have proposed before, i.e. an east African or Middle Eastern Afroasiatic homeland, and that it links it with the expansion of farming. However, we have to keep in mind that until 5,000 years ago the Sahara was not the desert we know: it had certain important green corridors, humid areas between megalakes. The Sahara might not have been exactly green 10,000 to 5,000 years ago (roughly the time when Afroasiatic must have been spoken), but it had certain regions that allowed for an east-west migration. However, it also allowed for a west-east migration, and – perhaps more importantly – for a sizeable population expansion in central Saharan territory. To forget that is to allow for potentially wrong assumptions to be made.

What we expect from the next papers on ancient African DNA samples are the result of certain (more recent) population – and thus potentially ethnolinguistic – movements, but they probably won’t solve the question of the Afroasiatic homeland, which has an older time span than the samples studied. There is a wide void in African prehistory – compared with Near Eastern history – and this research will be closing that gap, just like European samples are helping close the gap in the prehistory of western, northern, and eastern Europe, compared to the history of the eastern Mediterranean regions.

Diachronic map of Paleolithic migrations of R1b lineages in Europe and Africa

I already wrote, regarding the potential ethnolinguistic link between Indo-European and Afroasiatic, that a close look at the migration of R1b-V88 lineages from Europe (through southern Italy?) into the Sahara – through the Fezzan-Chad-Chotts, and Chad-Chotts-Ahnet-Moyer megalake green corridors – could have been the key to the successful expansion of Afrasians.

Interesting aspects to take into account are the distribution of R1b-V88 lineages, compared to the location of Chadic languages (probably the most divergent and least known of the group) and to the potential North Afroasiatic (composed by Egyptian, Berber, and Semitic) and South Afroasiatic group (made of Cushitic and Omotic). Chadic has been argued to be connected variously to North Afroasiatic, or to the Berber branch, but the Northern group has also been argued to be connected with Cushitic, with Omotic as an independent branch. Also interesting would then be the potential connection between Indo-European (or Indo-Uralic) and Afroasiatic.

r1b-map
Modern distribution of haplogroup R1b, from Wikipedia

We could speculatively place the potential primary Afroasiatic homeland in the south-central Sahara, near the Megachad lake (i.e. near the peak of R1b-V88 lineages), with a secondary homeland in eastern Africa (as in the map above) – and maybe a tertiary homeland (of North Afroasiatic) in the Middle East, associated with the expansion of “Natufians” and E1b1b subclades. The identification of the spread of Afroasiatic languages with the expansion of R1b-V88 lineages needs an anthropological context (linguistic and archaeological) that is obviously lacking today.

It is important to keep all possibilities in sight when reviewing genetic analyses.
