Deep in the Congo rivers provide food for some of our closest relatives, bonobos. A troop of bonobos wade in the shallows fishing for insect larvae, using delicate fingers to pick them out. Though closely related to chimps, bonobos are altogether more aquatic apes - they're more at home in water as a result of their longer legs. In the evening, they need to find a dryer place to settle down, and head to the trees to build nests among the branches. Lacing branches together they make beds. The bonobo's ancestors were cut off from the rest of the common chimps long ago by the Congo River. Because they couldn't swim, they were isolated and evolved into a different species.
