"Based on what you have seen in Lucy's skeleton compared to a human's skeleton, and how the genus Homo evolved their own traits beyond what Lucy had, did bipedalism or high intelligence evolve first in hominins? (1 point) Bipedalism evolved first in hominins. High intelligence evolved first in hominins.

The earliest hominid fossil, “Lucy,” is estimated to be 3.2 million years old. This early human-like species shares an important characteristic with modern humans: bipedalism. Which of the following would favor the selection of bipedal posture over walking on all fours? Bipedal posture allowed for greater mobility in the tree canopy. Bipedal posture allowed arms to be free to develop and use tools. Bipedal posture allowed for an increase in hominid brain and jaw size. Bipedal posture allowed a greater number of offspring to be produced in hominids.

Based on fossil evidence, what is the relationship between the evolution of bipedalism and large brains in hominin evolution? Bipedalism preceded large brains by millions of years. The first hominins had small brains and were quadrupedal, while later hominins had large brains and were bipedal. They co-evolved. Large brains preceded bipedalism by millions of years.
