British scientists have eliminated one potential explanation for the Neanderthals' extinction 26,000 to 32,000 years ago. Using a core sample of ocean sediment drilled from Venezuela's Cariaco Basin, researchers from the University of Leeds concluded that there were no significant changes in climate during the period. That leaves elimination of the Neanderthals by modern humans as the most likely explanation, they reported Thursday in the journal Nature.

Whales left land permanently about 45 million years ago.

They were huge, lumbering and certainly not the most graceful of creatures, but when they had to, dinosaurs sure could run, according to British scientists. Using prints from a fossilized dinosaur track in a quarry from southern England, a team from the University of Cambridge calculated that bipedal theropod dinosaurs such as Tyrannosaurus rex could run at speeds of up to 19 mph.
