A Nukak man hunting for monkeys outside San José, using a blowgun and darts tipped with curare. Luca Zanetti for The New York Times.
A fascinating report from the New York Times: A stone age tribe (actually, a band) walks out of the Amazon jungle to civilization. These people subsisted on monkeys (hunted with blow guns), nuts and seeds. Every day was another desperate hunt for food. This was what life was like for most humans until approximately 7500 years ago.
