Chimps remain friends for years
We're familiar with male bonding in human society. Chums bumping chests at a football game, buddies hanging out around the barbecue, talking about cars, work and girls. Guys going hunting together, sharing a beer, doing business together. Rarely do we think of male bonding as a non-human primate activity. Yet, it is a phenomenon that has been documented among chimpanzees and is being talked about. We now know that chimps remain friends for a long time .
