- I Believe that the first humans originated from east Africa because 1st thing Leakey made the grand breaking ant the famously bipedal ape Lucy was found. Also a woman name Mary discovered an Australopithecus skull in Tanzanians Olduvai Gorge,
A year later the Leakey found a major fossil. t.They also found more fossils and bones. That is why i think first humans was originated from east of Africa.
