Zebra2

In addition to the three living species, some fossil zebras have also been identified. Equus koobiforensis is an early zebra or equine basal to zebras found in the Shungura Formation, Ethiopia and the Olduvai Gorge, Tanzania, and dated to around 2.3 mya.[21] E. oldowayensis is identified from remains in Olduvai Gorge dating to 1.8 mya.[34] Fossil skulls of E. mauritanicus from Algeria which date to around 1 mya appears to show affinities with the plains

. Zebras and asses diverged from each other close to 2.8 mya and zebra ancestors entered Africa around 2.3 mya. The mountain zebra diverged from the other species around 1.75 mya and the plains and Grévy's zebra split around 1.5 mya.[13][20][21]

Zebras communicate with various vocalisations, body postures and facial expressions. Social grooming strengthens social bonds in plains and mountain zebras.

Zebras inhabit eastern and southern Africa and can be found in a variety of habitats such as savannahs, grasslands, woodlands, shrublands, and mountainous areas.
