CARTA: Domestication and Human Evolution - Robert Franciscus: Craniofacial Feminization in Evolution

Robert Franciscus (Univ of Iowa) explains that anatomically modern humans are recognized in the fossil record primarily by retraction and diminution of the facial skeleton compared to pre-modern “archaic” humans. He then describes a promising model for the advent of facial diminution, which suggests that anatomically modern humans represent a ‘self-domesticated’ species where selection for increased social tolerance led to growth and developmental alterations producing craniofacial “feminization,” which itself results in a phenotypic signal of reduced aggressiveness.
