Solution:
There is evidence that almost all of the Hominid evolution occurred in Africa and Asia and that the evolution of the human species took place in Africa. Several species belonging to the genusHomo can be recognized from the fossil record. For example,Homo habilislived in Africa, about two million years ago and was characterized by having a larger brain thanAustralopithecus,used tools, and was bipedal. Another species,Homo erectusappeared about 1.7 million years ago, used fire, and is believed to have migrated to Asia and Europe. Fossils of the so-called 'Java man' and 'Peking man', belong toHomo erectus. Homo erectuswas replaced by Homo sapiens.Homo erectusappears to have survived for another 250,000 years when it was finally replaced byHomo sapiensmigrating from Africa.
