Smaller teeth may be favored by natural selection because teeth weren"t used as tools. Lower jaw had a jutting chin for the first time. Smaller than the value for neanderthals but greater than the value for other hominins in the late middle pleistocene. Still more heavily built than contemporary human population. Relied less on body strength and more on tools. Body proportions similar to people who live in warm climates and may reflect the african origins of these people. 13. 2 the origin and spread of modern humans.
