THERE'S NO SUCH THING AS SPECIES:

Human ancestors 'less ape-like' (Daily Telegraph, 4/13/09)

Human ancestors living millions of years ago were bad at climbing trees and not nearly as ape-like as many experts believe, new research suggests.

Scientists came to the conclusion after studying ankle joints from "hominins" dating back more than four million years.

The creatures lived a relatively short time after humans and chimpanzees split from a common ancestor four to eight million years ago.
