The two principal component analyses below are the most useful and straightforward that I’ve ever come across. They’re very easy to understand for normal people who don’t know anything about genetics. The first is a PCA of the entire human species, and the second only features Caucasoids (aka West Eurasians). I made them into infographic type images, and included some extra labels, maps, and the sources. I haven’t edited the PCAs other than fixing the ratio on the global humanity PCA, because the ratio used in the study is misleading.

I made three versions, one with both PCAs on one image, and two featuring only one PCA each.

PCA of modern humans worldwide

PCA of West Eurasians only
