Lecture 4: primate and early human evolution10/11/2012 2:11:00 pm. General patterns of morphology and phylogentics for fossil primates. What a hominin is in terms of taxonomy. Morphological trends in hominin evolution: bipedalism, exampnsion in brain size, changes in dental/cranial features. The earth is constantly changing and will continue to constantly change: massive effects. Geography and climate: very different from present-day conditions, hotter more humid. Were first thought to be the earliest kinds of primates. Recent: plesiadapids are not primates (began in. Two main eocene primate families: adapidae. Body size: 100 g to 6900 g. Mainly arboreal duqdrupeds, some may have been specialized leapers. Smaller adapids ate mostly fruit and insects, largers forms ate more fruit and leaves. One of the few animals to be capable of digesting leaves: remarkable adaptation. Body size of 45 g to 2500 g. Teeth: adapted for eating insects and soft fruits, only a few species were leaf-eaters.
