The hominoids are descendants of a common ancestor. Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that includes all the great apes. [ 1] This process involved the gradual development of traits such as human bipedalism, dexterity ...
