Anthropologists will be in disagreement as to this tribe's "uncontacted" status. Some have already said they may be the remnants of an earlier encounter that fled deeper into the jungle. Here is a link to the original article : "Uncontacted" Tribe Seen in Amazon (Nat'l Geo.), and the NY Times treatment: Isolated in Amazon, Visible From the Air. My concern is the photos themselves. They just seem wrong. The colors appear to be exaggerated.
