Question

Quizplus · Accepted Answer

Australopithecus afarensis is considered a hominin because it exhibits bipedalism, meaning it walked on two legs, which is a characteristic that distinguishes hominins from other primates. The other options do not necessarily distinguish hominins from other primates - many primates lack a tail, thin molar enamel is not exclusive to hominins, and although Australopithecus afarensis did have a relatively larger brain than earlier hominins, it was still much smaller than modern humans.
