Afanasievo, Okunev, Andronovo, Sintashta DNA?

A reader alerts me to this article in Russian, but you can use Google Translate to get the gist of it. Some interesting bits (note that "pit"=Yamna): I can not ignore the question I now have is particularly exciting - the origin of the Indo-Europeans. Show More Summary

Icelanders galore

A set of four papers in Nature Genetics today. All open access. Of interest from the Y-chromosome paper:When this rate was applied to estimate the TMRCA between two Y chromosomes that encompass the oldest known patrilineal bifurcation...Show More Summary

Campanian Ignibrite and Neandertal demise

Geology doi:10.1130/G36514.1Campanian Ignimbrite volcanism, climate, and the final decline of the NeanderthalsBenjamin A. Black1, Ryan R. Neely2,3,4 and Michael Manga1The eruption of the Campanian Ignimbrite at ca. 40 ka coincided with the final decline of Neanderthals in Europe. Show More Summary

British origins (Leslie et al. 2015)

The long-awaited paper on the People of the British Isles has just appeared in Nature. I will update this entry with more information.Nature 519, 309–314 (19 March 2015) doi:10.1038/nature14230 The fine-scale genetic structure of the British population Stephen Leslie et al. Show More Summary

Natural selection and ancient European DNA

A new preprint on the bioRxiv studies the same data as the recent Haak et al. paper, but focuses on natural selection in Europe. Until recently, selection could only be studied by looking at modern populations, but since selection is...Show More Summary

Bottleneck in human Y-chromosomes in the last 10,000 years.

A very exciting new paper has just been published in Genome Research on 456 full sequence Y-chromosomes from around the world. The authors date the MRCA of Y-chromosomes ("Y chromosome Adam") to 254 (95% CI 192–307) kya, find coalescences...Show More Summary

PNAS doi: 10.1073/pnas.1421784112 Genome-wide ancestry of 17th-century enslaved Africans from the Caribbean Hannes Schroeder, María C. Ávila-Arcos et al. Between 1500 and 1850, more than 12 million enslaved Africans were transported to the New World. Show More Summary

Sveti Ivan relics Middle Eastern, mid-1st century AD

Irrespective of one's religious beliefs, a genome from the mid-1st century AD would be interesting. I am personally in favor of the scientific study of saints' relics.Bulgarian bones could be John the Baptist's, scientists saySo when...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
