The prehistory of New World Arctic (Raghavan et al. 2014)

Science 29 August 2014: Vol. 345 no. 6200 DOI: 10.1126/science.1255832 The genetic prehistory of the New World ArcticMaanasa Raghavan et al. The New World Arctic, the last region of the Americas to be populated by humans, has a relatively well-researched archaeology, but an understanding of its genetic history is lacking.

Ancient Y-DNA from China

From the paper: Dividing the samples further using social status shows that the six aristocrats had haplogroups Q1a1, O3a, and N, the 14 commoners had haplogroups Q1a1, O3a, and O, and the seven slaves had haplogroups O3a, O2a, and O (Fig. Show More Summary

Neandertal demise followed contact with modern humans (but not immediately)

Important:Southern Iberia has been held to represent an exception to a wider European pattern21, with late survival of Neanderthals previously argued at sites such as Gorham’s Cave, Gibraltar22. We could not reproduce any of the late...Show More Summary

Tuberculosis is 6,000 years old

... and sea mammals (not Europeans) introduced it to the New World.Nature (2014) doi:10.1038/nature13591Pre-Columbian mycobacterial genomes reveal seals as a source of New World human tuberculosis Kirsten I. Bos et al. Modern strains...Show More Summary

Indo-Europeans preceded Finno-Ugrians in Finland and Estonia

According to an abstract of a Ph.D thesis (below). This would appear to work well with the dating of the signature Y-chromosome haplogroup of Finno-Ugrians. Bidrag till Fennoskandiens språkliga förhistoria i tid och rum (Heikkilä, Mikko)My...Show More Summary

ISBA 2014 titles

Some interesting talks and posters from the upcoming International Symposium on Biomolecular Archaeology. I don't see any abstracts on the site (yet?) but the titles are intriguing. Some that caught my eye: Investigating the maternal...Show More Summary

mtDNA from Chalcolithic Iberia (El Mirador cave)

A very exciting new study from Chalcolithic Iberia. The authors compare their mtDNA data with those from the Brandt et al. (2013) paper which includes German samples from the same time.The following plot seems quite useful. From its caption:This study: El Mirador (MIR). Show More Summary

168 South Asian Genomes

PLoS ONE 9(8): e102645. doi:10.1371/journal.pone.0102645 The South Asian Genome John C. Chambers et al. The genetic sequence variation of people from the Indian subcontinent who comprise one-quarter of the world's population, is not well described. Show More Summary

New estimates of human mtDNA node dates and substitution rates (Rieux et al. 2014)

This is a quite useful paper as it compares different methods of obtaining mutation rate estimates, either using "archaeological calibration" based on known migration events or ancient mtDNA genomes (with known archaeological dates)....Show More Summary

mtDNA haplogroup V7 from ~5,000-year old kurgan of the Novosvobodnaya culture

I am not sure that the finding of a single mtDNA V7 sample suggest "a role of the TRB culture in the development of the Novosvobodnaya culture", or, indeed with the labeling of the TRB as "Indo-European". In any case, it's good to see some ancient DNA from the North Caucasus.Acta Naturae. Show More Summary

Dairy farming transition ~2,500 years ago in the far north of Europe

Proceedings of the Royal Society B doi: 10.1098/rspb.2014.0819 Neolithic dairy farming at the extreme of agriculture in northern Europe Lucy J. E. Cramp et al. The conventional ‘Neolithic package’ comprised animals and plants originally domesticated in the Near East. Show More Summary

Abstract BACKGROUND: Multiple 20th century studies have speculated on the anthropological similarities of the modern inhabitants of Greece with their ancient predecessors. Show More Summary

Wine cup of Pericles found

Wine cup used by Pericles found in grave north of AthensExperts are "99 per cent" sure that the cup was used by the Athenian statesman, as one of the other names listed, Ariphron, is that of Pericles' elder brother. "The name Ariphron is extremely rare," Angelos Matthaiou, secretary of the Greek Epigraphic Society, told the newspaper. Show More Summary

Lethal mutations quantified

k-means and structure

I was reading one of the many negative reviews of Nicholas Wade's new book when I came across this statement:"The problem is that Structure, which uses an algorithm called “k-means,”"I pointed out that Structure does not use k-means and a small discussion ensued on twitter. Show More Summary
