This is not too surprising, as nature does tend to show some intelligible patterns which can be cross-checked with different methods (e.g., the fact of…
African genetic structure

We studied 121 African populations, 4 African American…
The secret history of Africa

Since the 1950s paleoanthropological studies have suggested variability in this group. Different sub-groups have been identified in western Europe, in southern Europe and in…
