If reckoned from the Australopithecus represented by Lucy, there has been three million years of anthropological evolution. In this long process, humans have evolved from the anthropoid ape to the homo sapiens and have propagated from Africa to all five continents. Humans then endured the transition from the Paleolithic Age to the Neolithic Age, from hunting-gathering to agriculture and to husbandry. In a short duration of 5000 years, human civilization witnessed an epic drama.
