How many stages do the archaeologists use to find out the remains of the early man? List them. Explain any 2
Answers
Explanation:
In the 1930s, paleoanthropologists Louis and Mary Leakey unearthed early stone artifacts at Olduvai Gorge in Tanzania and named them the Oldowan tool culture. In the 1960s they found hominin fossils (in association with those Oldowan tools) that looked more like later humans -- and assigned them to a new species, Homo habilis, handy man.
"Conventional wisdom in human evolutionary studies since has supposed that the origins of knapping stone tools was linked to the emergence of the genus Homo, and this technological development was tied to climate change and the spread of savannah grasslands," says Dr. Lewis, a Research Assistant Professor at TBI. "The premise was that our lineage alone took the cognitive leap of hitting stones together to strike off sharp flakes, and that this was the foundation of our evolutionary success."
But a series of papers published in early 2015 have solidified an emerging paradigm shift in paleoanthropology -- Australopithecus africanus and other Pleistocene hominins, traditionally considered not to have made stone tools, have a human-like trabecular bone pattern in their hand bones consistent with stone tool knapping and use.
