Inventing the whites, what hath fog wrought?
One of the first posts on this blog relating to archaeogenetics involved an essay by me involving reflections on the fact that a particular Y chromosomal haplogroup, N1c (N3a now), had a peculiar distribution which ranged from Siberia to Finland. The argument, at the time, was whether it was a lineage which moved east to…

European hunter-gatherers were mostly replaced, but not totally. And they were neither black nor white
Peter Frost over at his blog has a long post on the transition to agriculture and pastoralism in Northern Europe. He tagged me on Twitter, so presumably, he’s soliciting my opinion/response. The post starts off with a quick reference to the attempt to leverage massive replacement in Northern Europe eight to four thousand years ago…

A new press release is circulating on the paper which I blogged a few months ago, Ancient Admixture in Human History. Unlike the paper, the title of the press release is misleading, and unfortunately I notice that people are circulating it, and probably misunderstanding what is going on. Here’s the title and first paragraph: Native…

The Sardinian meter
I cropped the image above from the paper Inference of Population Structure using Dense Haplotype Data. The main reason was emphasize the distinctiveness of the Sardinian cluster, on the bottom right. As you can see this population exhibits a lot of co…

Really fine grained genetic maps of Europe
A few years ago you started seeing the crest of studies which basically took several hundred individuals (or thousands) from a range of locations, and then extracted out the two largest components of genetic variation from the hundreds of thousands of variants. The clusters which fell out of the genetic data, with each point being…
