Climate change likely drove early human species to extinction, modeling study suggests

Of the six or more different species of early humans, all belonging to the genus Homo, only we Homo sapiens have managed to survive. Now, a study reported in the journal One Earth on October 15 combining climate modeling and the fossil record in search of clues to what led to all those earlier extinctions of our ancient ancestors suggests that climate change–the inability to adapt to either warming or cooling temperatures–likely played a major role in sealing their fate.
