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.
Hells Canyon Wilderness (Oregon and Idaho)
Wildlife is abundant in Hells Canyon Wilderness. Black bear, cougar, elk, deer, mountain goat, chukar, and bighorn sheep are common. There have been reports, documented as recently as the late 1970s by local Forest Service and agriculture workers, of grizzly bears in the Wilderness. Wolves have established small packs in the area, and moose, peregrine falcon, bald and golden eagles can also be seen. Recent research has photodocumented the presence of wolverines.
