Their common ancestor would have lived in the Miocene, about 20 million years ago. Hippopotamids are therefore deeply nested within the family Anthracotheriidae. The Hippopotamidae are believed to have evolved in Africa; the oldest known hippopotamid is the genus Kenyapotamus , which lived in Africa from 16 to 8 million years ago. While hippopotamid species spread across Asia and Europe, no hippopotamuses have ever been discovered in the Americas, although various anthracothere genera emigrated into North America during the early Oligocene.

While hippopotamid species spread across Asia and Europe, no hippopotamuses have ever been discovered in the Americas, although various anthracothere genera emigrated into North America during the early Oligocene. Taxonomists disagree whether or not the modern pygmy hippopotamus is a member of Hexaprotodon — an apparently paraphyletic genus, also embracing many extinct Asian hippopotamuses, that is more closely related to Hippopotamus — or of Choeropsis, an older and basal genus.
Extinct species Three species of Malagasy hippopotamus became extinct during the Holocene on Madagascar , one of them within the past 1, years. The Malagasy hippos were smaller than the modern hippopotamus, likely through the process of insular dwarfism. All three species became extinct before the last glaciation.

Why sensitivity occurs When the protective layers of teeth are worn away, a bony tissue called dentin is exposed. This tissue contains microscopic hollow tubes that, when exposed, allow hot and cold liquids and food to contact the underlying nerve endings in the teeth, causing pain. Unprotected dentin is also vulnerable to cavity formation. Plugging these tubes with a mineral called nanohydroxyapatite is a long-standing approach to treating sensitivity.
