Climate Change May Have Spurred Human Evolution: Scientific American
Jared Sperli stashed this in science
An ancient lake whose shores vacillated between lush forests and dry savannahs shows how the changing climate may have shaped humanity's dawn in eastern Africa, according to new research.
Scientists studying organic remains dating back 2 million years in Olduvai Gorge in Tanzania tracked how plant life adapted to the regional climate as it shifted from regular monsoons to scorching dry spells. The researchers published their findings last week in the Proceedings of the National Academy of Sciences.
Three cheers for climate change! :)
