describe the history of at least three major discoveries that led to our current understanding of hominid evolution?

The history of three major discoveries that led to our current understanding of hominid evolution are as follows.

Explanation:

Raymond Dart a South African anatomist, discovered a skull of a young hominoid with a brain case and facial structure similar to an ape. He classified the organism as a new primate species. Australopithecus Africans which means Southern Ape from Africa.

An American Paleoanthropologist, Donald Johanson, Discovered the complete australopithecine skeletons that he called "lucy". The size of the braincase suggests that their brains had a small, apelike volume and not a larger human volume.

In 1964, anthropologists Louis and Mary Leakey described skull portions of another type of hominid in Tanzania. Leakey classified the hominid with modern humans in the genus Homo. Because stone tools were found near the fossil skull and named Homo Habilis means "handy human".
