You can't help but laugh when you watch this:
They really do love their sex. Seriously; it's so funny. We share 97% DNA with Bonobos (Pan paniscus). We share 99% DNA with Chimpanzees (Pan troglodyte), which is the violent and territorial of the two species in the genus. Hmm... if only we could be more like the Bonobos, and hippies... "make love not war".
Peace, Love, Happiness.
