We begin 7 million years ago when our ancestors started walking on two legs, moving out of the forests onto the savannahs. We will examine the unintended consequences of evolutionary biology's development of the upright primate. This lectures covers our primate cousins, gorillas, chimpanzees and bonobos and what we can learn from them and how we diverged from the common ancestor. Bi-pedalism is the first evolutionary step towards becoming modern Homo Sapiens. Technology, migration and all later developments stem from being upright. An example is the freeing up of the hands from walking which in turn disconnected breathing from walking. The development of omnivory occurs during this time span as well.
