Climate change would be the cause for which the great animals of North America became extinct

Un nuevo estudio publicado en Nature Communications suggests that the extinction of North America's largest mammals was not driven by the overhunting of rapidly expanding human populations following their entry into The Americas.. Instead, findings, based on a new approach to statistical modeling, suggest that large mammal populations fluctuated in response to climate change, drastic decreases in temperatures 13.000 years initiating the decline and extinction of these massive creatures. Even so, humans may have been involved in more complex and indirect ways than simple models of over-hunting suggest.
