THE MYSTERY: Since the discovery of the famed "hobbit fossil," researchers have wrangled over whether the find was a human ancestor or a modern human suffering from a genetic disorder.
NEW CLUE: A study of the bones in the creature's left wrist lends weight to the human ancestor theory, according to a new report.
WHY: The wrist bones are basically indistinguishable from an African ape and nothing at all like that seen in modern humans.
