ad small skulls, small brain cases,projecting faces, large chewing teeth and looked ape-like. Looking at Lucy, my tour guide pointed out herprimitive limb proportions. Although she did walk upright on two legs, her legs were very short, adopted toclimbing, indicating that she may have taken shelter in the trees at night. We can also observe that Lucyhad very long hands. The proportion of her hands in comparison to her short legs would implicate that shewalked in a different fashion than the way we do today. She would have had to swing her arms around,making her motions similar to those of an ape. Five million years after Lucy, Australopithecus africanus appears. This creature also walkedupright but lived in relatively open country and obtained food mainly by gathering and scavenging. Australopithecus africanus’ face did not project as far as his ancestors, had smaller incisor teeth and aslightly larger brain compared to body size. I enjoyed the exhibit of Australopithecus africanus because itshowed what he would have looked like with flesh. It looked like a hairy, short cross between man and ape. In the same exhibit as Lucy was “Turkana boy”. He was found in 1984 at Nariokotome, Kenya. Turkana boy existed about 1.6 million years ago and looks more like modern man. The Turkana boy wasfive feet three inches and weighed one hundred and six pounds. Although we would view his skeletal heightas that being one of an adult, his bones were those of an adolescent. It was believed that if he had lived tomaturity, he would have grown to about six feet one inch and would have weighed approximately onehundred and fifty pounds. The proportions of his body maximized the surface area to best shed body heat ina hot dry open environment. He was more advanced than Lucy and had increased brain cell capacity andhad rock tools which was evidence of hand crafted tool kits which were primitive but sophisticated. Turkana boy came...
