Our closest relative, the peaceful Bonobo ape. They live in the deep part of the jungle where not many creatures can survive so there is not too much competition for food. The bonobos have evolved to be very sociable, friendly animals. They go around in small troops but enjoy meeting other troops of bonobos, often teeming up for a while. They look like chimps but they are a completely different species. They are very chilled out, like afternoon naps, and make lifetime friendships. It looks like a fantastic life.
Charles Darwin was right, we became the most successful creature on the planet because of our collective nature where we help each other, just like the bonobos do.
I thought this was a fantastic documentary.
