Homo sapiens much older than thought?

The general theory, until recently, was that our own species evolved only some 200,000 years ago, a half-million years after the migration out of Africa. Teeth found in Israel, though, may complicate this picture considerably. According to Israeli researchers, the teeth are from "modern" humans - but are 400,000 years old. While the discoverers are cautious (they will keep digging, looking for skulls and bones that might reinforce their theory) and other anthropologists think the claim isn't proven yet, the find raises the possibility that the first H. sapiens arose in what would become known as the Holy Land. That might mean one group of ancient humans pushing out from Africa settled this region and eventually developed into a new species - us.
