Here is a picture of the process of evolution. We are supposedly the product of the overall human evolution. The first and basic pre evolutionary human/primate was the Pliopithecus. Then slowly, the primates began accumulating some traits of the human. The primates transformed to humans, as the backs became erect, they started losing hair, and their bones became larger. Scientists have come to the conclusion that there were 14 species before the human in that specific evolution process.
