A friend of mine proudly told me recently that she’d purchased an unabridged edition of The History and Geography of Human Genes. Turns out that there are some affordable used copies floating around (under $50, like the Atari 2600!).

Below are the 1000 Genomes data, with 250,000 markers (I pruned by intersecting with HGDP markers as well as those with very low missingness):
