(Visit: ) 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.
