A geometric morphometric approach to the quantification of population variation in sub-Saharan African crania.
the cranial measurements of modern African populations.
When we began this discussion we were talking about Out of Africa ( OoA) events,
and the cranial measurements of the exiting population. As I made it clear overtime
the brow and eyebrow ridges have decreased, That is why you find marked differences
between the ancient craniums and modern craniums. The most ancient Blacks have
prominent sloping ridges.
Below is the ancestor of Neanderthals
Here is a picture of Neanderthal man
By 100kya Neanderthal looked like this
As you can see, there is little difference between the African ancestor of Neanderthals,
and the Neanderthals themselves who migrated out of Africa into Europe, both
populations have broad or prominent eyebrow ridges . Theonly modern Negro
population with prominent eyebrow ridges are the Australians.
Contemporary African and Black amh populations have less prominent brow and
eyebrow ridges beginning with Cro-Magnon man. Here we have Cro-Magnon or
Note the less prominent eyebrow ridges. That is why the authors in the articles you cited did not find too much variation between and among contemporary African populations may they be Bantu or Khoisan and Anu (Pygmy).
As you can see there was a difference between the eyebrow ridges of the earliest OoA migrants and contemporary Black and Afro-Indo populations.
Denisovans were also Blacks.
Note the sloping eyebrow ridges of this hominid that reflect the prehistoric human form.
Note the less prominent eyebrow ridges among amh like Grimaldi man.
