Early hominins likely had to lose some of their climbing abilities in order to obtain efficient bipedality.

Question

Quizplus · Accepted Answer

In order to efficiently walk on two legs, early hominins had to undergo anatomical changes such as a different positioning of the foramen magnum, a longer and more robust femur bone, and changes in the structure of the foot. These changes likely came at the cost of losing some climbing abilities, as the anatomy that allows efficient bipedality is not well-suited for arboreal locomotion.
