Question

Quizplus · Accepted Answer

Australopithecus afarensis is known for its bipedalism, or ability to walk on two legs, which is one of the key features that distinguishes it from other primates. B is incorrect because Australopithecus afarensis had a relatively small brain compared to modern humans. C is incorrect because primates with tails are typically quadrupedal, not bipedal. D is incorrect because prognathism, or a protruding jaw, is not a unique feature of Australopithecus afarensis and is seen in other primates as well.
