Our Tree-Climbing Human Ancestors Could Walk Upright Like Us, Study of Chimps and Other Primates Shows

Science, 4.2.18

As part of a study led by Graduate Center Professor Herman Pontzer, GC Ph.D. student Elaine Kozma filmed chimps, bonobos, gorillas, gibbons, and other primates in zoos so she could measure the precise angles of their legs and hips when they walked upright. She then calculated the stresses on their bones during maximum extension and found that apes put a lot of force on their massive thighs, hamstrings, and knees — forces that also help them power up trees.
