Insanity Posted December 28, 2012 #1 Share Posted December 28, 2012 Erratic Environment May Be Key to Human Evolution At Olduvai Gorge, where excavations helped to confirm Africa was the cradle of humanity, scientists now find the landscape once fluctuated rapidly, likely guiding early human evolution.These findings suggest that key mental developments within the human lineage may have been linked with a highly variable environment, researchers added. Olduvai Gorge is a ravine cut into the eastern margin of the Serengeti Plain in northern Tanzania that holds fossils of hominins — members of the human lineage. Excavations at Olduvai Gorge by Louis and Mary Leakey in the mid-1950s helped to establish the African origin of humanity. http://www.livescience.com/25793-changing-environment-human-evolution.html Link to comment Share on other sites More sharing options...
