Derived Features of Anatomically Modern Humans Included

Question

Derived features of anatomically modern humans included
A) thicker bones.
B) a rounded skull.
C) a lack of a mental eminence (no chin).
D) shorter stature across the entire species.

Accepted Answer

Anatomically modern humans have a more rounded skull compared to their earlier ancestors. This is attributed to changes in the brain structure, such as increased brain size and the development of a more complex frontal lobe. Thicker bones (A) are not a derived feature of anatomically modern humans, as they typically have thinner bones compared to earlier hominids. The lack of a mental eminence (C) or chin is a feature of some early hominids, but not of anatomically modern humans. Finally, anatomically modern humans are generally taller than earlier hominids, so D is also not a derived feature.
