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

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

A very interesting new preprint on the arXiv (so it can be freely read). The founder population is the Hutterites. The key sentence:Our approach indicates that on average, one in every two humans carries a recessive lethal allele onShow More Summary

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

Armed conflict in the Sahara, ~13 thousand years ago

An interesting story from the Independent: Scientists are investigating what may be the oldest identified race war 13,000 years after it raged on the fringes of the Sahara. French scientists working in collaboration with the BritishShow More Summary

Neandertal-like temporal labyrinth of Xujiayao 15

From the press release:While it's tempting to use the finding of a Neandertal-shaped labyrinth in an otherwise distinctly "non-Neandertal" sample as evidence of population contact (gene flow) between central and western Eurasian Neandertals...Show More Summary

Altitude adaptation in Tibetans came from Denisovans
