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.
Red Buttes Wilderness
The Wilderness is home to a wide variety of animals. Black-tailed deer are common, while black bear, coyotes, bobcats, ring-tail cats, and mountain lions are less common but still may be seen. A number of small mammals, particularly members of the rodent and weasel families, inhabit the area. Many species of birds can be seen in the Wilderness, including eagles, hawks, falcons, goshawks, owls, Steller's jays, and ravens.
