Olduvai Gorge (ōl`dəwā', –vā'), a feature of the E African Rift Valley in Tanzania. Erosional processes have exposed geological strata in the gorge dating to the lower Pleistocene epoch, about 1.8 million to 600,000 years ago. The site was made famous by the numerous hominid fossils excavated by Louis Leakey Leakey, Louis Seymour Bazett (băz`ət, lē`kē), 1903–72, British archaeologist and anthropologist of E Africa, b.

Both the fossils and the tools have been important lines of evidence in understanding human evolution human evolution, theory of the origins of the human species, Homo sapiens. Modern understanding of human origins is derived largely from the findings of paleontology , anthropology , and genetics , and involves the process of natural selection (see Darwinism ).

Olduvai Gorge

Archaeological site on the eastern Serengeti Plain, northern Tanzania. It is a steep-sided ravine about 30 mi (48 km) long and 295 ft (90 m) deep. Deposits exposed in the sides of the gorge cover a time span from c. 2,100,000 to 15,000 years ago and have yielded the remains of more than 50 hominins as well as the most complete sequence of stone tool industries. The site first came to public notice in 1959 when Louis and Mary Leakey (see Leakey family) uncovered the first specimens of Paranthropus, a hominin related to Australopithecus. Remains of Homo habilis, Homo erectus, and Homo sapiens have since been found. These discoveries have strengthened the argument that the human lineage originated in Africa.
