Question

Quizplus · Accepted Answer

Evidence of bipedal locomotion is a key feature that differentiates hominins from apes. This includes changes in the pelvis, femur, and foot that allowed for efficient walking on two legs.

Answer: B
 Hominins also have smaller posterior teeth compared to apes, reflecting changes in diet and feeding behavior.

Answer: C
 Large canines are a feature of many ape species, but hominins have smaller, less prominent canines. This may reflect a reduction in male-male aggression and a shift towards more social and cooperative behaviors.

Answer: D
 The loss of a tail is not a unique feature of hominins, as many primate species lack tails. Therefore, this is not a distinguishing factor between hominins and apes.
