The term
anatomically modern human (AMH) in
paleoanthropology refers to early individuals of
Homo sapiens with an
appearance consistent with the
range of phenotypes in modern humans.
Anatomically modern humans evolved from
archaic Homo sapiens in the
Middle Paleolithic, about 200,000 years ago. The emergence of anatomically modern human marks the dawn of the subspecies
Homo sapiens sapiens, i.e. the subspecies of
Homo sapiens that includes all modern humans. The oldest fossil remains of anatomically modern humans are the
Omo remains that date to 195,000 years ago. Other fossils include
Homo sapiens idaltu from
Herto in
Ethiopia that are 150
kya and remains from
Skhul in Israel that are 90,000 years old.
Anatomy
Anatomically modern humans are distinguished from their immediate ancestors, archaic
Homo sapiens, by a number of anatomical features. Archaic
Homo sapiens had robust skeletons, indicating that they lived a physically demanding life; this may mean that anatomically modern humans, with their more
gracile 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
brow ridges (protruding layers of bone above the
eye socket). 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...
