Humans drove the final nail in woolly mammoths coffin
Climate change drove woolly mammoths to the edge of extinction and then humans finished them off, according to a Spanish study that adds to the debate over the demise of the Ice Age behemoths. Using climate models and fossil remains, the researchers determined that warming temperatures had so shrunk the mammoths' habitat that when humans entered their territory about 6,000 years ago the species were already hanging by a thread.
