Diagram of a rift valley's future evolution into a sea Satellite image of a graben in the Afar Depression. Today these rifts and faults are seen as distinct, although connected, but originally, the Great Rift Valley was thought to be a single feature that extended from Lebanon in the north to Mozambique in the south, where it constitutes one of two distinct physiographic provinces of the East ...
The Great Rift Valley is part of an intra-continental ridge system that runs through Kenya from north to south. It is part of the Gregory Rift, the eastern branch of the East African Rift, which starts in Tanzania to the south and continues northward into Ethiopia. [ 1] It was formed on the "Kenyan Dome" a geographical upwelling created by the ...
The Olduvai Gorge or Oldupai Gorge in Tanzania is one of the most important paleoanthropological localities in the world; the many sites exposed by the gorge have proven invaluable in furthering understanding of early human evolution. A steep-sided ravine in the Great Rift Valley that stretches across East Africa, it is about 48 km long, and is ...
The East African Rift ( EAR) or East African Rift System ( EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. [ 1] It was formerly considered to be part of a larger Great Rift Valley that extended north to Asia Minor .
Great Rift Valley, Ethiopia. The Great Rift Valley of Ethiopia, (or Main Ethiopian Rift or Ethiopian Rift Valley) is a branch of the East African Rift that runs through Ethiopia in a southwest direction from the Afar Triple Junction. In the past, it was seen as part of a "Great Rift Valley" that ran from Mozambique to Syria .
Kariandusi prehistoric site is an archaeological site in Kenya. Located on the southeastern edge of the Great Rift Valley and on Lake Elmenteita, Kariandusi is an African Early Stone Age site dating to approximately 1 million years ago. [ 1]
That favorability, the scientists predicted, drove the evolution of long necks. Since its inception, the necks-for-sex sexual selection hypothesis has overshadowed Darwin’s and Lamarck’s necks ...
The Great Rift Valley of Africa provides critical evidence for the evolution of early hominins.The earliest tools in the world can be found there as well: An unidentified hominin, possibly Australopithecus afarensis or Kenyanthropus platyops, created stone tools dating to 3.3 million years ago at Lomekwi in the Turkana Basin, eastern Africa.
