Anatomically modern humans are distinguished from their ancestors, archaic homo sapiens, by a number of anatomical features, but the differences are fuzzy.

Archaic homo sapiens had robust skeletons, indicating that they lived a physically demanding life; this may mean that anatomically modern humans, with their more ] frames, had become more dependent on technology than on raw physical power to meet the challenges of their environment. Archaic homo sapiens also had very prominent ]s (protruding layers of bone above the ]). With the emergence of anatomically modern humans, the brow ridges had significantly reduced, and in modern humans they are, on average, barely visible. Another distinguishing feature of AMH is a prominent chin, something which is lacking in archaic homo sapiens.

AMH also have a vertical ] whereas their predecessors had foreheads that sloped backwards.<ref></ref>{{Refimprove|cited below references to Desmond Morris book 'The Naked Woman: A Study of the Female Body chapter The Brow do has any relation to AMH, Is any paleo-context there?|date=August 2009}} According to ], the vertical forehead in humans not only houses larger brains, but the prominent forehead plays an important role in human communication through ] movements and forehead skin wrinkling.<ref>{{cite book|title=The Naked Woman: A Study of the Female Body|chapter=The Brow|chapterurl=http://books.google.com/books?id=Wa9zntiEKeAC&printsec=frontcover#PPA22,M1|last=Desmond Morris|authorlink=Desmond Morris|year=2007|isbn=0312338538}}</ref>
