Everything You Ever Wanted To Know About Elephant Evolution

Elephant mtDNA and nuclear DNA phylogeny from Meyer et al. 2017. The Neumark-Nord (NN) and Weimar-Ehringsdorf (WE) straight-tusked elephants are indicated. The mtDNA tree has a time scale (bottom) but the nuclear DNA tree has no time scale associated with it.
John Hawks has a lengthy and fact filled post about our improved understanding of the evolution of the elephant (most species and clades of which are extinct now), which has been enhanced recently by ancient DNA and new paleological finds. Some important parts of this evolution happened while modern humans existed.

"My own research on this dwarf elephant, Palaeoloxodon falconeri has shown that this remarkable species had an exceptionally large brain. In fact, it’s the only animal species ever recorded with a brain size comparable to a human’s."

The palaeoloxodan antiquus has been extinct for 120 000 years. This elephant roamed Europe and western Asia during the last ice age, about 400 000 years ago. A study of its DNA shows that this supposedly European animal is actually the African forest elephants’ closest relative.
