How human races evolve from Africa?
Human evolution is a gradual process that took place slowly in time. All human beings on the earth regardless of their skin colour and other features belong to a single species called Homo sapiens. All human beings evolved from primates in Africa.
Human beings share common ancestory with gorillas and chimpanzees. Various changes in our ancestors occurred through mutation or other ways of bringing the variations. These changes kept on accumulating over generations and gradually resulted into speciation of new species called Homo sapiens (human beings).
The different stages of human evolution from ancestral primates to modern human beings are as follows:
Dryopithecus and Ramapithecus
Man like primates
Australopithecus(Homo habilis )
Homo erectus
Homo neanderthalensis
Homo sapiens
Ramapithecus and Dryopithecus were two primates that lived around 15 mya and are considered ancestors of human. They were hairy and walked like gorillas and Chimpanzees.Then from them evolved man like primates around 3-4 mya, that were not so tall but walked straight like man.Australopithecus also called Homo habilis evolved around 2 mya. They used some stone weapons and ate fruits. They were human like.Then from them, evolved Homo erectus and then Homo neanderthalensis. Homo sapiens evolved from Homo neanderthalensis around 75,000 -10,000 mya.
