This species has a smaller and more specialised range than its larger counterpart, in small areas of Central Africa. It is thought that the Pygmy Hippopotamus diverged from the //Hippopotamus// genus some 7 million years ago. |
| ===== I. HIPPO EVOLUTION ===== | Two sub-species are recognised - but only one is believed to be of extance. The Western Pygmy Hippopotamus, //C. l. liberiensis//, is found in areas of western Africa, with most being found in the country of Liberia. The Nigerian, or Eastern Pygmy Hippopotamus, //C. l. heslopi//, is found in countries east of the Liberian range - but has not been observed since the early 20th century, and is thought to be extinct. |
| Hippo fossils are relatively rare, so the evolution of the hippopotamus is still not largely understood. However, the hippopotamus shares a common ancestor with whales, which are thought to have evolved from small, four-legged land-living animals. However, it is thought that hippos and whales evolved aquatic lifestyle separately. Perhaps by taking to the water, the hippo could avoid predators by taking an unused niche. The ancestral hippo lived about 15 million years ago, and would spread around Europe and Africa. The hippos with more resources would grow larger in size, especially in Europe. However, those with less resources would shrink in size. Before the last Ice Age, only the African Hippos remained, and today, only two hippopotanoids live today - the Hippopotamus, and the Pygmy Hippopotamus, the smaller of the two. The Pygmy Hippopotamus belongs to the same family, but to a different genus. | |
