One of the interesting aspects ensuing from the rise of molecular phylogenetics is that the trees are generally concordant in broad strokes with older research which was based on morphology. 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

I’ve been fine tuning Ubuntu all day with goodies and getting drivers to work right, so I missed this paper on African genetics: Africa is the source of all modern humans, but characterization of genetic variation and of relationships among populations across the continent has been enigmatic. We studied 121 African populations, 4 African American…

The secret history of Africa

In light of the relatively recent interaction of Bantu farmers and Pygmies in Central Africa, this paper is of note, Genetic and demographic implications of the Bantu expansion: insights from human paternal lineages: The expansion of Bantu languages, which started around 5,000 years before present (YBP) in west/central Africa and spread all throughout sub-Saharan Africa,…

Neandertal phylogeography

Genetic Evidence of Geographical Groups among Neanderthals: The Neanderthals are a well-distinguished Middle Pleistocene population which inhabited a vast geographical area extending from Europe to western Asia and the Middle East. 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…
