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 Elk Wilderness
The Black Elk Wilderness is located in the U.S. state of South Dakota. The wilderness was designated by an act of Congress in 1980. Managed by the U.S. Forest Service, Black Elk Wilderness is part of Black Hills National Forest. This 13,426 acre (54 km²) region is considered sacred to Native Americans, especially the Sioux and is named after Black Elk, an Oglala Sioux holy man. Mount Rushmore National Memorial is immediately to the north and much of the rest of the wilderness is bordered by other protected land under the jurisdiction of state and federal agencies.
