We weren’t supposed to have chins
Lauren Schroeder, a paleoanthropologist who studies craniofacial evolution, discusses why only humans have chins. She walks through competing ideas like function, sexual selection, and byproduct. She explains how jaw and face changes driven by diet, bipedalism, and brain size may have left the chin as a secondary outcome.
