Wildebeest "Gorgon", while the black wildebeest belonged to the genus "Connochaetes". Today, they are united in the single genus "Connochaetes", with the black wildebeest being named ("C. gnou") and the blue wildebeest ("C. taurinus"). According to a mitochondrial DNA analysis, the black wildebeest seem to have diverged from the main lineage during the Middle Pleistocene and became a distinct species around a million years ago. A divergence rate around 2% has been calculated. The split does not seem to have been driven by competition for resources, but instead because each species adopted a different ecological niche and occupied a different trophic
