These charts don't show what you apparently think they do. The samples in the larger datasets (like the HGDP) are chosen for their differentiation, often from indigenous groups, with admixture samples usually removed (the first adds in a few admixture types for the specifics of their study).
- nhchris 4y agoIf my statement wasn't true, there would be no way to distinguish admixture from indigenous in the first place.
- magicalist 4y agoYour statement was "people living in the same country are indeed more closely related to each other than to people of different countries" The first chart shows a direct counterexample with "African American", "Mexican American" and "North America" groups more separated from each other than from other groups and yet many of them live in the same country. These are also not the only groups of people you'd find in North America, they're just the ones used in the study of Northwestern american indigenous groups that this is screenshotted from. This is, again, poor evidence for your claim.
- nhchris 4y agoCountries that had recent significant immigration are an exception, and their population will reflect the genetics of their geographic origins. I.e. African-Americans are closer related to Africans than to Italian-Americans. I thought this was obvious enough to not require a disclaimer.
