Craniometrics Show Differences between AMH and Prehistoric Man

Cranial differences exist between amh and prehistoric African populations. The indication of cranial phenotypic differences is mainly in cranonical variates relating to brow and eyebrow ridges. The most ancient Blacks have prominent sloping ridges. Succeeding amh have less prominent brow and eyebrow ridges.


The articles below show slight variations among and within the contemporary populations 
being studied.

This is not surprising you would not expect to see too much variation between
 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.

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
 Aurignacian man


Contemporary Afro-Indians


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.
