For the first time, Primatologists have observed chimps in the wild spreading a cultural fad through their troop.
Things I Learned as a Field Biologist #65: "Collecting the fecal matter of your study subject is an art form, and not nearly as simple as one might think. In a perfect world, you would look through your binoculars into the canopy and see the prized excrement emerge freshly from the posterior of the exact animal you’re hoping to sample.

Talking Primates with Frans de Waal: Frans de Waal is a primatologist who's challenged male supremacy in evolution, the belief that monkeys don't perceive images as we do, and the idea that they don't possess emotions ascribed to humans.

Make love not war. Amoung humans closest relatives, these monkeys solve conflict by makeing love. A lot. Female dominate society they have no homicide and tensions in the group are non existent.
