hes do for us. It was a way of insulating their bodiesagainst such things as wind.The next exhibit was on Homo habilis, which was the earliest member of human lineage to havemade stone tools. Fossils found date Homo habilis to have lived about 2 to 1.5 million years ago. They areincluded in our genus Homo because of the evidence found that links them to stone making. Their toolswere small and quite crude but with a few blows from a hammer-stone, the toolmaker would knock sharpflakes from a cobble. The flakes were then used for cutting and scraping and the shaped core may havebeen used for chopping. The stone making allowed for a more varied diet. While they killed the animals bythrowing rocks at them, they could now carve them with the sharp flakes of stone. The body proportions ofHomo habilis was for the most part similar to that of Australopithecus. However, we see an enlargementof the brain case but the head and teeth become smaller. They no longer relied on the tough vegetarian dietso the muscles in the head did not need to be as strong as before. Homo ergaster appears between 2 to 1million years ago and used stone tools much like those of Homo habilis.Next appears Homo erectus, who dated about 2 million years ago and thought to be the earliestforms which we might recognize as actual human life. Their Brain was smaller than ours, however, largerthan the early human fossils. Erectus had a human like skull, and the brain was one thousand milliliters involume which was not far from the average, which is fourteen hundred milliliters. The brain of Homoerectus was housed in a long , low braincase, sharply angled at the back and the eyes were overhung bybony ridges. Although their chewing teeth and jaw structure were large in respect to our own, compared toHomo habilis, these features were small. Some of the members are as tall as us and they were advancedenough to use fire. They were followed by a group of intermediate hu...
