Olduvai Gorge, located in Tanzania, is an important archaeological site that holds clues to the origins of early human species. It is particularly important to human evolution research as it is home to the world’s oldest evidence of human technology and the large number of Stone Age tools discovered here suggest that early humans lived in the area between 1.2 and 1.7 million years ago. For anyone who is interested in the history of human evolution, Olduvai Gorge is an important place to visit.
