What geographic characteristics of East Africa may have helped preserve hominid remains?
Which geographic characteristics of East Africa may have helped to preserve hominid remains? They found tools near the human fossils. Why did the Leakeys think that homo habilis used tools?
Is the region of Africa were many early hominid hominin fossils have been discovered?
The types of sediments and the geological contexts likely to yield hominid fossils are known. We just have to look for the right deposits. So far, early hominids have only been discovered in eastern and southern Africa, with the exception of the Chad Basin in central Africa.
In what part of Africa are the earliest hominid remains?
Scientists have long looked to East Africa as the birthplace of modern humans. Until the latest findings from Jebel Irhoud, the oldest known remnants of our species were found at Omo Kibish in Ethiopia and dated to 195,000 years old. Other fossils and genetic evidence all point to an African origin for modern humans.
What volcanic area have most African hominid fossils been found?
To date, three major types of geological megastructures have yielded almost all fossil remains of early hominids: the East African Rift Valley (EARV), the intracratonic basin of Lake Chad, and the fossil‐rich cave deposits in South Africa.
Why has the Great Rift Valley of Africa been so important to paleoanthropologists?
The Rift Valley in East/Northeast Africa has been an important source of Basal Pleistocene and Pliocene fossils because this geological phenomena has exposed deposits from these time periods for fossil hunters to explore.
What part of Africa did the first human appear?
The earliest humans developed out of australopithecine ancestors after about 3 million years ago, most likely in Eastern Africa, most likely in the area of the Kenyan Rift Valley, where the oldest known stone tools were found.
