Question

Quizplus · Accepted Answer

Homo ergaster had a taller skull, which is a derived feature shared by modern humans. This is seen in the increased cranial capacity and elongated shape of the skull, which is different from the more robust and flat skulls of earlier hominins.

Answer: C
 Homo ergaster did not have a chin, which is a derived feature shared by modern humans. This is seen in the lack of a projection of the anterior mandible, which creates a smooth curve from the lower jaw to the neck. This is different from the more protruding and angular mandibles in earlier hominins.

Therefore, the correct answer is A and C.
