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 wolf
Black wolves rarely occur in Europe and Asia, where interactions with domestic dogs have been reduced over the past thousand years due to the depletion of wild wolf populations. They have occasionally appeared, as wolf-dog hybrids are known in Russia as "black wolves", and currently, 20–25% of Italy's wolf population is composed of black animals. They are more common in North America; about half of the wolves in the reintroduced wolf population in Wyoming's Yellowstone National Park are black. Like Pyrenees Wolves, Black wolves do not live in France. In southern Canada and Minnesota the black phase is more common than the white, though grey coloured wolves predominate.
