(See a list of all 35 vanished genera of North American Ice Age mammals.) But some skeptics, Grayson among them, have asked where's the evidence? Grayson and archeologist David Melzer of Southern ...

and that they expanded from these areas as global temperatures warmed following the ice age. Other mammals (such as beavers and lynx) expanded from glacial refugia to the east of Europe only to ...

We humans may or may not have killed off the giant mammals of the Ice Age. But we are unquestionably threatening innumerable species today, as we expand relentlessly into ever more of their habitats.

The scientists are yet to release findings from the study, but previous studies of Ice Age mammals have yielded insights into the specimen's diet and relation to modern species. At the time of ...

It reveals how these large marine mammals have adapted—and sometimes failed to adapt—to such pressures since the height of the last Ice Age thousands of years ago. Today, the largest southern elephant ...

Our research will test current hypotheses to explain body size variation in ice-age mammals, including: Temperature: Large animals are better adapted to cold periods as they conserve heat more ...

We will then combine these datasets into ecological niche models (ENMs) in order to identify the most important factors (climatic change, vegetation change, humans) for determining the past ...
