Document Summary
Lecture 1: when and where did the first humans appear: there are approximately 190 species of non-human primates. Primates have a few commonalities: limbs and locomotion, dentition, senses and the brain, development, orgins from arboreal life. Five digits: partially opposable thumb, nail instead of claws, except in some new world monkeys, tactile pads with nerves at ends of fingers to enhance touch of sense. Senses and the brain: colour vision; diurnal have it, nocturnal don"t, depth perception, stereoscopic vision allows to see in three dimensions, binocular vision-both eyes set toward front of head. When and where did the first humans appear: multidisciplinary-experts from various scientific diciplines, physical sciences, eg:geology, biological sciences and social sciences, paleoanthropology: the study of fossil. So when did humans evolve from other primates: evidence lies in analyses of fossils from hominin/hominid ancestors who lived in east and south africa, bipedal ancestors from humans.
