mtDNA from Lengyel culture in Poland

PLoS ONE 10(2): e0118316. doi:10.1371/journal.pone.0118316 Between the Baltic and Danubian Worlds: The Genetic Affinities of a Middle Neolithic Population from Central Poland Wies?aw Lorkiewicz et al. For a long time, anthropological...Show More Summary

Y chromosome mutation rate: 0.82x10-9

This is in Russian, but seems to be using Anzick-1, Ust-Ishim, K14 to get the mutation rate. Fu et al. who just used Ust Ishim got 0.7-0.9 for this which seems very similar, and also identical to the 0.82x10-9 value of Poznik et al.Show More Summary

8,000 year old wheat in Britain

Britain received farming later than most of Europe, but perhaps it received one of the products of farming well before any farmers set foot on the island. I've always wondered if news (and at least some products) of the agricultural revolution spread far and wide before the revolution itself did. Show More Summary

Two observations on the ancestry of Armenians

I was thinking a bit on how to interpret the findings of the new Haber et al. preprint, and especially the idea that "29% of the Armenian ancestry may originate from an ancestral population best represented by Neolithic Europeans." I...Show More Summary

The plight of the Assyrians

ISIS Onslaught Engulfs Assyrian Christians as Militants Destroy Ancient ArtISTANBUL — The reports are like something out of a distant era of ancient conquests: entire villages emptied, with hundreds taken prisoner, others kept as slaves; the destruction of irreplaceable works of art; a tax on religious minorities, payable in gold.

Estonian biocentre high coverage Y chromosome sequences and Turkic data

Courtesy of the good people of the Estonian biocentre: 307 high coverage human Y chrmosome sequences. Paper to be published soon. The Genetic Legacy of the Expansion of Turkic-Speaking Nomads Across Eurasia. Paper in press. The Y chromosome data seems particularly exciting (there is a spreadsheet of populations in the download directory). Show More Summary

KNM-LH1: a 23,000 year old human from Kenya

From the paper: KNM-LH 1 and other Pleistocene African specimens, all of which are potentially sampling candidate populations for dispersals across and out of Africa during the Late Pleistocene (12–15, 50, 59), differ substantially not only from recent Africans but also from individuals drawn from Holocene LSA archaeological sites.

Mutation rate again (Lipson et al. 2015)

This estimate is in-between 1.2 and 2.5x10-8, the two most quoted values for this parameter. It seems like such an important number that I'm wondering if it would be possible to brute force estimate it. Maybe people who have whole genomes...Show More Summary

Spread of Leprosy into Medieval Europe

Infection, Genetics and EvolutionVolume 31, April 2015, Pages 250–256 A migration-driven model for the historical spread of leprosy in medieval Eastern and Central Europe Helen D. Donoghue et al. Leprosy was rare in Europe during the Roman period, yet its prevalence increased dramatically in medieval times. Show More Summary

Scandinavian team looking for Indo-Europeans in Kazakhstan

An article in the Astana Times. If anyone has any additional information via Kazakh or Scandinavian media, or can find the press release referred to in the article, feel free to share. Scandinavian Team Searches for Indo-European Homeland...Show More Summary

Italic "Eteocretan" Sea peoples?

Stranger things have happened...TALANTA XL-XLI (2008-2009), 151-172 AN ‘ETEOCRETAN’ INSCRIPTION FROM PRAISOS AND THE HOMELAND OF THE SEA PEOPLESLuuk de Ligt The whereabouts of the homeland or homelands of the so-called Sea Peoples have been endlessly debated. Show More Summary

Y chromosomes and Catalan surnames

Some really rich data in the supplements.European Journal of Human Genetics advance online publication 18 February 2015; doi: 10.1038/ejhg.2015.14 Y-chromosome diversity in Catalan surname samples: insights into surname origin and frequency Neus Solé-Morata et al. Show More Summary

Multiple opportunities for Out-of-Africa

Geology doi: 10.1130/G36401.1 Alluvial fan records from southeast Arabia reveal multiple windows for human dispersal Ash Parton et al. The dispersal of human populations out of Africa into Arabia was most likely linked to episodes of...Show More Summary

Bronze Age mixing of multiple populations => Armenians (?)

As far as I can tell, the hypothesis of "several mixtures" comes from looking at many pairs of populations and seeing that different types of pairs seem like they mixed to make Armenians. Possibility (1) is that Armenians have multiple mixtures, and possibility (2) is that none of the sources work very well.Hellenthal et al. Show More Summary

Late (not necessarily steppe) split of Proto-Indo-European

This is the paper that I saw referenced in a previous study. As I suspected, the paper does not in fact provide support specifically for the steppe hypothesis, but only for a late split of Proto-Indo-European (that is consistent with the steppe hypothesis but not unique to it). Show More Summary

Turkic language family time depth: 204BC

From the paper:The regular-sound-change tree estimates a mean divergence time between the outgroup Chuvash and other Turkic languages of 204 BCE, with a 95% credible interval of 605 BCE to 81 CE. This compares to proposals from glottochronological...Show More Summary

Why do East Asians have more Neandertal ancestry than Europeans?

This is quite the paradox, because even though Neandertals are now known to have existed all the way to the Altai, they were still overall a West Eurasian-distributed species. As far as I can tell, three explanations have been proposed:...Show More Summary

A story of 69 ancient Europeans

A new study on the bioRxiv includes data on 69 ancient Europeans (remember when we got excited in anticipation for the single genome of the Iceman? that was only three years ago) and adds plenty of new info to chew on for those of us interested in prehistory. Show More Summary

A genetic map of the British population

This article is a review that presents a genetic map of the British Isles from an upcoming study by Leslie et al. (2014) that is listed in the references as being "in press" in Nature. This may very well be the big POBI study of the British Isles that has been talked about for years now.Genetics February 1, 2015 vol. Show More Summary

Improving access to endogenous DNA in ancient bones and teeth

A new technical paper on the bioRxiv. Of interest is the group of samples, which includes some nice additions, including Bronze Age Hungary, Iron Age Denmark, and Post-1200AD Easter Island. Hopefully, we'll see genomes from these regions...Show More Summary
