A Savage Hoax: The Cave Men Who Never Existed

Cover of the John Nance book about "The Gentle Tasaday."

Last month a photograph released by advocacy group Survival International showed painted tribesmen in a remote Amazon village brandishing bows. They were said to have never had contact with the outside world.

Some media misreported the tribe as "lost" and previously unknown. This week the affair was incorrectly labeled a hoax by other news outlets. Finally, Survival International countered yesterday that it's no hoax. The group was not lost or unknown, it had just been "uncontacted."
