(Q020) While reading an article for your archaeology class, you come across a section in which the author lays out a claim for why the Mesolithic foragers with long and narrow skulls were replaced by the agriculturalists with short and wide skulls in Nubia. Why is this claim that "short-headed" people came in and replaced all the "long-headed" people likely false

This is likely false because craniofacial changes can be attributed to long-term diet changes
