Diet <strong>and</strong> Health 43Unlike apes, their jaw was slightly bow-shaped. And their dentitionsuggests that some were omnivores <strong>and</strong> others, vegetarians.The omnivores were slightly built <strong>and</strong> the vegetarians, heavysethominids (genus Australopithecus <strong>and</strong> esp. A. robustus <strong>and</strong> A. boisei)were heavily built, taller, <strong>and</strong> muscular, characterized by heavy molars<strong>and</strong> small incisors adapted to a vegetarian diet. A. robustus had strongjaw muscles <strong>and</strong> large, heavily cusped molars. This hominid may havespecialized in chewing seeds, nuts, <strong>and</strong> other tough plant materiaLA.africanus was probably omnivorous. It's cheek teeth formed aplatform that could grind plants, but its incisors were relatively large, asin the case for carnivores.By about 2.5 million years ago, hominids started making stone tools<strong>and</strong> are referred to as the" early Homo". Compared to the australopiths,these "early Homo's", had a smaller face, more generalized teeth, <strong>and</strong> alarger brain. This hominid apparently was a scavenger <strong>and</strong> gatherer ofplant material, small animals, <strong>and</strong> insects.
