Tanzania plays the largest part in human discovery and world-renowned status. The name Olduvai is a misspelling of Oldupai Gorge, which was adopted as the official name in 2005. Oldupai is the Maasai word for the wild sisal plant which grows in the gorge. Laetoli is a site in Tanzania, dated to the Plio- Pleistocene and famous for the hominin footprints preserved in it’s volcanic ash. The site of the Laetoli footprints (Site G) is located 45 km south of Olduvai Gorge. The location and tracks were discovered by archaeologist Mary Leakey in 1976, and were excavated by 1978. Based on analysis of the footfall impressions “The Laetoli Footprints” provided convincing evidence for the theory of bipedalism in Pliocene hominins and received significant recognition by scientists and the public. The Olduvai Gorge, in Tanzania is one of the most important paleoanthropological sites in the world, and has proven invaluable in furthering our understanding of early human evolution. This gorge is steep-sided ravine in the Great Rift Valley that stretches across East Africa. It is about 48 kilometres (30 miles) long, and is located in the eastern Serengeti Plains in the Arusha Region not far (about 45 km /28 mi), from Laetoli, another important archaeological site of early human occupation. The British/Kenyan paleoanthropologist- archeologist team Mary and Louis Leakey established and developed the excavation and research programs at Olduvai Gorge which achieved great advances of human knowledge Tanzania The Promised Land 18
