Document Summary
Four principal groups of interest in early hominin evolution. All of these groups represented in eastern africa, the first two also in chad and latter 3 are found in south africa. The earliest probable hominins have smaller molars and are more thinly enameled then later australopiths, suggests a diet of fleshy fruits and soft, young leaves. Craniodental morphology of later australopithecus (thickly enameled large, flat cheek teeth and heavily crania and mandibles compared with living apes) reflects an adaptive shift from diets dominated by soft, sugary fruits to hard, brittle nuts or seeds, Larger teeth with well-buttressed skulls and massive chewing muscles of. Paranthropus have led to notion that robust relied on more hard foods than australopithecus. The easter africa hyper robust p. boisei has been considered the quintessence of this but cracking morphology. Earliest members of homo genus believed to have had tools to acquire and process a broad range of foods, such as meat and underground storage organs.
