The black wildebeest was first discovered in the northern part of South Africa

This has not always been the case, and at one time the latter was placed under a separate genus of its own, "Gorgon". The black wildebeest lineage seems to have diverged from the blue wildebeest in the mid- to late Pleistocene, and became a distinct species around a million years ago. This evolution is quite recent on a geologic time scale. Features necessary for defending a territory, such as the horns and broad-based skull of the modern black wildebeest, have been
