Question
Which of the following features distinguishes Homo sapiens from its ancestors? a. increased brain size b. walking upright c. reduced jaws d. hairless body
Correct Answer
Option A is the correct answer.
Detailed Explanation
While Homo sapiens have reduced jaws and relatively hairless bodies compared to some ancestors, the most distinguishing feature that set them apart, especially from earlier hominins like Homo erectus and Neanderthals, is a significantly larger and more complex brain. Upright walking is a much older trait.
