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

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

This is somewhat strange given that Denisova cave is not at high altitude. Nature (2014) doi:10.1038/nature13408 Altitude adaptation in Tibetans caused by introgression of Denisovan-like DNA Emilia Huerta-Sánchez et al. As modern humans...Show More Summary

Chimp mutation rate is equal to human mutation rate but driven more by males

This is important because (a) it shows evidence for the "slow" mutation rate in a species related to humans, (b) it shows that chimp and human mutation rates are equal and so using the human mutation rate in studies of divergence with chimps is justified, and (c) it is driven differently by males/females than in humans.Science 13 June 2014: Vol. Show More Summary

An older layer of Eurasian admixture in Eastern Africa

The authors propose that a genetic component found in Horn of Africa populations back-migrated to Africa from Eurasia ~23 thousand years ago. I did not read this carefully yet, but it seems reasonably plausible. The migration uncovered by Pagani et al. Show More Summary
