Arial photographs released in May by the Brazilian government of an "uncontacted" tribe deep in the Amazon have generated a sense of wonderment back here in civilization. Even today, in this age of computers and globalization, there still exists groups of humans living as their ancestors have lived, basically unchanged for thousands of years.

This tribe and similar ones in "Brazil" and particularly near the Brazilian and Peruvian "border" — words that mean nothing to these people — have been known about but likely have had no contact with outside groups for generations or perhaps ever.
