Document Summary
Humans are the most widely distributed living primate species. During the course of human evolution, we have expanded into many different. Biological adaptations have aided humans in new environments (such as cold weather, environments high altitudes) Cultural adaptations of humans have allowed greater expansion: enabled us to range far beyond our biological limitations, permitted incredible population growth. Ape"s skull is characterized by a relatively small brain and large face, modern humans have relatively large brains and small faces. The human brain is not only larger than the brain of a chimpanzee, but also structurally different. The increased convolution of the human cerebral cortex (the folding of brain tissue) means that the brain of a human child with the same volume of a chimpanzee has more cerebral cortex. Bipedal moving about on two legs. Unlike the movement of other bipedal animals, such as kangaroos, human bipedalism is further characterized by a striding motion.
