Uncontacted tribes aren't 'Stone Age.' They just want — and deserve — to be left alone
The death last month of Christian missionary John Allen Chau, at the hands of the uncontacted island tribe he had hoped to evangelize, triggered a thorny debate. Was the Indian government, which oversees North Sentinel Island, keeping the people of this tribe in a glass museum box or protecting their freedom? Some scientists assert that these isolated tribes cannot survive without some intervention from outside.
