Q

East African Rift Valley

A

“Cradle of Humankind” due to the many important fossil sites it contains, such as Olduvai Gorge, Hadar, and Laetoli, where early hominins like Australopithecus and Homo habilis have been discovered. The valley’s varied landscapes, including savannas, forests, and volcanic activity, played a significant role in shaping early human traits like bipedalism and tool use.
