The Grévy's zebra is found in thorny scrubland of East Africa, while the African wild ass inhabits rocky deserts of North Africa.
These insects appear to be less attracted to striped coats and, compared to other wild equines, zebras live in areas with the highest fly activity.
The first equids were small, dog-sized mammals (e.g.
Eohippus) adapted for browsing on shrubs during the Eocene, around 54 million years ago (mya).
The plains zebra lives in lush grasslands and savannas of Eastern and Southern Africa, while the Mountain zebra inhabits mountainous areas of southwest Africa.
The other equine species tend to occupy more arid environments with more scattered vegetation.
