Olduvai Gorge

Olduvai Gorge, located in Tanzania, is a crucial paleoanthropological site that has significantly contributed to our understanding of early human evolution. This steep-sided ravine in the Great Rift Valley has revealed a wealth of fossils, particularly of early hominins such as Homo habilis, Paranthropus boisei, and Homo erectus, dating back to 1.9 million years ago. The site is also notable for the discovery of the oldest known stone tools, categorized as Oldowan, which provide insight into the cognitive and social development of early humans. The gorge's rich stratigraphy, with layers ranging from the Lower Pleistocene, has preserved a diverse array of faunal remains and evidence of early human activity, underscoring its significance in the study of human ancestry.
