A remote and un contacted village
The Yanomami people are hunter-gatherers. They live in small, remote villages deep in the Amazonian rainforest. Westerners first encountered Yanomami people in the 1960s.
In 2008 researchers arrived in one of their villages. People living there -- all 54 of them -- said they had never seen Westerners before.
The Yanomami people and their chief permitted researchers to collect samples from their body.
