As we send back images from the recent Mars Lander it still amazes me that there is so much to uncover on our own planet. According to Survival International there are up to a 100 undiscovered tribes in the world with over half in he Brazilian rainforest. This is a prime example where the BBC reports an undiscovered Amazonian Tribe. An aircraft took several images of the tribe who were clearly perturbed by the presence of this outsider, firing their arrows at it. The BBC attempted to decipher the images of the Maloca which is the central meeting place.
