In Prehistoric Fossils, a Surprising Find on Aging

Mouselike mammals lived a lot longer than modern-day counterparts, say scientists

(Newser) - Two sets of fossils found 40-something years apart suggest that small mammals who lived during the mid-Jurassic period had a longer "childhood" and a more stretched-out life span than their contemporary counterparts. The new research published Wednesday in the journal Nature examined the fossilized remains of Krusatodon kirtlingtonensis, a...

With Great Ape Discovery, a Possible Evolutionary Bombshell

Study suggests Europe was a hotbed for great ape evolution, and possible cradle of humanity
