A continuation of current climate trends could eliminate the primary food source of polar bears amid fierce competition with grizzly bears as the two species are forced into a shared habitat, said evolutionary biologists at the University of California, Los Angeles. The scientists used 3-D computer modeling to compare the skull and jaw strength of polar bears and brown bears, and found that polar bears are less suited to processing the tough omnivorous or herbivorous diets of their grizzly...

Whales are remarkably diverse, with 84 living species of dramatically different sizes and more than 400 other species that have gone extinct, including some that lived partly on land. Why are there so many whale species, with so much diversity in body size? To answer that, UCLA evolutionary biologists and a colleague used molecular and computational techniques to look back 35 million years, when the ancestor of all living whales appeared, to analyze the evolutionary tempo of modern whale...

UCLA biologists, colleagues solve mystery contemplated by Charles Darwin When Charles Darwin visited the Falkland Islands during the voyage of the Beagle in 1835, he saw a wolf-like species, wrote about it in his diaries and correctly commented that it was being hunted in such large numbers that it would soon become extinct. Darwin was baffled by how this animal got on the islands, and it figured heavily in the formation of his ideas on evolution by natural selection. Now, UCLA biologists and...

Ever since the Falklands wolf was described by Darwin himself, the origin of this now-extinct canid found only on the Falkland Islands far off the east coast of Argentina has remained a mystery. Now, researchers reporting in the November 3rd issue of Current Biology who have compared DNA from four of the world's dozen or so known Falklands wolf museum specimens to that of living canids offer new insight into the evolutionary ancestry of these enigmatic carnivores. "One of the big draws for an...
