Humans really don’t need chins

Popular Science reported on research from Noreen von Cramon-Taubadel on the development of the chin, which does not have an evolutionary advantage. “Just because we have a unique feature, like the chin, does not mean that it was shaped by natural selection to enhance an animal’s survivability, for example a buttress for the lower jaw to help dissipate the forces of chewing,” said von Cramon-Taubadel. “The chin is likely a byproduct, not an adaptation."
