Blue wildebeest
This species of wildebeest seems to have evolved around 2.5 million years ago. The black wildebeest is believed to have diverged from the blue wildebeest to become a distinct species around a million years ago, in the mid- to late Pleistocene. Fossil evidence suggests that blue wildebeest were quite common in the Cradle of Humankind in the past. Apart from eastern Africa, fossils are commonly found in Elandsfontein, Cornelia, and Florisbad.
Black-capped squirrel monkey
The black-capped squirrel monkey ("Saimiri boliviensis") is a South American squirrel monkey, found in Bolivia, Brazil and Peru. This South American monkey can be found in numerous zoos (with over 80 zoos keeping them in Europe alone, the majority of them being of the Bolivian subspecies) around the world, including the Ellen Trout Zoo, London Zoo, Apenheul Primate Park, Copenhagen Zoo and Auckland Zoo. Black capped squirrel monkeys are flexible omnivores, with diets including insects, fruits, flowers, eggs, and even small vertebrates (NeuroImage, Academic Press).
