So - remember going to the zoo as a kid? Depending on which zoo you went to, you got to see one of two types of elephants: either the small-eared Asian Elephant or the large-eared African Elephant. Well now knew research shows that the "African" elephant is actually two separate species: a forest dwelling elephant and a savanna dwelling elephant.
Why does this matter you ask? Because of the 500,000 or so "African" elephants, only about a fifth of them are of the forest dwelling species. African elephants are already considered an endangered species.
