Ice Age extinction claimed highly carnivorous Alaskan wolves

wolf bones preserved in permafrost and compared the sequences, called haplotypes, with those of modern-day wolves in Alaska and throughout the world. The fossils showed a wide range of haplotypes—greater in fact than their modern counterpart—but ther...

evidence that some early hominins, including Lucy ( Australopithecus afarensis ), lived in woodland environments, while even earlier forms such as Millennium Man ( Orrorin ) appear to have lived in the forest canopy and moved on two legs. "Our fin...
