Australopithecus boisei, an early hominoid, lived in Africa until about 1.2 million years ago during the Pleistocene epoch and is an ancestral link to modern Homo sapiens. The remains were uncovered by archaeologist Mary Leakey at Olduvai Gorge, Tanzania, a site serving as a treasure trove of other findings. Fossil records and genetic evidence increasingly and strongly suggest Africa as the birthplace of modern humans. Africans have the greatest genetic diversity, implying they have the longest lineage while strong genetic similarities in non-African people point to a more common and recent point of origin. Fossil discoveries, such as Australopithecus boisei, along with new findings and advanced scientific technology, provides us with clear and compelling evidence in the ancestral roots of describing how and when modern human beings emerged out of Africa.
