Genes and Geography (Italy vs. Britain)

January 16, 2020

All else being equal, genes mirror geography in Europe. We've already seen this by comparing Italians to Germans, and now we can do another similar comparison. A new study that has even better geographical coverage than Sazzini et al. (2016) shows the samples clustering to form an almost perfect map of Italy, while another new study shows the same thing in the British Isles.

[NOTE: For the samples in gray, "NWEur" is actually Southern French, "WEur" are Spanish and Portuguese, and "SEEur" is Greeks.]
