Fossils in South African cave reignite debate on origins of humankind

Fossils of early human ancestors in a cave in South Africa are a million years older than researchers previously thought, according to a study published this week that gives insight into the history of humankind.

The study of fossils from the Sterkfontein Caves, which yielded the near-complete skull of a cave woman nicknamed Mrs. Ples, found they date back 3.4 million to 3.6 million years.
