Science Café Cleveland: “Why Do Knuckle-Walking African Apes Knuckle-Walk?”

Walking on your knuckles is as odd as walking bipedally—a very peculiar way to get around. Only chimpanzees and gorillas do it, but it doesn’t make sense. This mystery has bothered anthropologists for years. No one has come up with the reason why—until now.

Researchers at Case Western Reserve University have cracked the evolutionary mystery. Join Scott Simpson, professor in the Department of Anatomy at the CWRU School Medicine, for this month’s Science Café Cleveland to discuss why knuckle-walking African apes knuckle-walk.

His talk, titled “Why Do Knuckle-Walking African Apes Knuckle-Walk?” will be held Monday, Nov. 12, from 7 to 8 p.m. at the Music Box Supper Club (1148 Main Ave.).

Doors will open at 5:30 p.m. Limited menu options will be available for purchase.

The Case Western Reserve University chapter of Sigma Xi, WCPN ideastream and the Music Box Supper Club sponsor Science Café Cleveland.
