Reich Lab et al. are now targeting more than 1.2 million sites in the ancient samples that they genotype, including over one million from the Illumina genotype array. This is great because it means that I can now run analyses with these ancients on the present-day populations in my Illumina array-based dataset using as many as 500K SNPs, which makes things more accurate and interesting. Below are a few sets of D-statistics of the form D(Outgroup,X)(Population1,Population2), featuring several ancient populations from the recent Allentoft et al., Haak et al. and Mathieson et al. papers. I'm basically testing how much closer X is to either Population1 or Population2. The results look very solid considering the spatio-temporal and archaeological origins of the samples. However, the outcomes for the smaller Northern European nations perhaps look slightly inflated. This is probably due to their peculiar demographic histories and resulting relative genetic homogeneity. At this stage, I don't know how to test this and limit its effects, if indeed it is a problem.
