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.
Blue wildebeest
The blue wildebeest is native to Angola, Botswana, Kenya, Mozambique, South Africa, Swaziland, Tanzania, Zambia, and Zimbabwe. Today, it is extinct in Malawi, but has been successfully reintroduced in Namibia. The southern limit of the blue wildebeest range is the Orange River, while the western limit is bounded by Lake Victoria and Mount Kenya. The blue wildebeest is widespread and is being introduced into private game farms, reserves and conservancies. So, the International Union for Conservation of Nature and Natural Resources rates the blue wildebeest as being of least concern. The population has been estimated to be around 1.5 million, and the population trend is stable.
