Man originated from earlier primates in eastern Africa. The big step in their evolution is the drying of eastern Africa about 4 million years ago. When the jungles died and separated, what would become man developed a locking knee joint. This enabled them to walk much farther (and endurance run) to cover more ground and obtain more resources, putting them at a distinct advantage to other primates. If you don't believe me, try walking around without locking your knee, it's hard and taxing.

This adaptation allowed for the development of many other things that we've come to love: our large heads and brains (when we were strictly bipedal, we free up our hands for projects, and this favors big brains), short rib cage (for flexibility), and big butts (something has to give you balance when you don't have a tail).

This climate change occurred when New Guinea moved in the way of a prominent current that brought warm, moist water to east Africa. Over time, these newly smart, adapted primates radiated out of Africa and to the rest of the world. See links below for more info.

Ethiopia is in east africa. Yes, the oldest hominids and the oldest modern human fossils have been found in Africa. So, ALL humans are originally of African ancestry.

People can only deny that if they ignore the facts. WHY isn't a question I can answer.
