"A research team led by Bay Area scientists has unveiled the oldest-known member of the human family tree: a 4.4 million-year-old female skeleton named 'Ardi,' who shares both chimp and modern human features. Believed to be capable of both climbing and walking, 'Ardi' reveals the early evolutionary steps that our ancestors took after we diverged from our common ancestor with chimpanzees. 'It's not a chimp. It's not a human. It shows us what we used to be,' said UC Berkeley paleoanthropologist Tim White, co-director of the research group that discovered and analyzed the fossils, which are described in a special issue of the Oct. 2 journal Science. 'It bridges a gap.'"
