In searching for the origins of humanity, what characteristic did scientists identify as the first step in human evolution?
- A.
Bipedal locomotion
- B.
Language
- C.
Art and imagination
- D.
Large brain
Correct Answer
A. Bipedal locomotionExplanation
Scientists have identified bipedal locomotion as the first step in human evolution.
