Zebras have a less efficient digestive system than ruminants but food passage is twice as fast. [15] Thus, zebras are less selective in foraging, but they do spend much time eating. The zebra is a pioneer grazer and prepares the way for more specialised grazers such as blue wildebeests and Thomson's gazelles. [9] Lions feeding on a zebra
Equus originated in North America and direct paleogenomic sequencing of a 700,000-year-old middle Pleistocene horse metapodial bone from Canada implies a date of 4.07 million years ago (mya) for the most recent common ancestor of the equines within a range of 4.0 to 4.5 mya. [20]
Zebras appear to be a monophyletic lineage [10] [11] [12] and recent (2013) phylogenies have placed Grévy's zebra in a sister taxon with the plains zebra. [10] In areas where Grévy's zebras are sympatric with plains zebras, the two may gather in same herds [13] and fertile hybrids do occur. [14]
The zebras were being transported from Washington to Montana when the driver took the Interstate 90 exit for North Bend, located about 30 miles (48 kilometers) southeast of Seattle, to secure the ...

Mountain zebras live in hot, dry, rocky, mountainous and hilly habitats. They prefer slopes and plateaus as high as 2,000 m (6,600 ft) above sea level, although they do migrate lower during winter. Their preferred diet is tufted grass, but in times of shortage, they browse, eating bark, twigs, leaves, buds, fruit, and roots. They drink every day.
Chapman's zebra are native to savannas and similar habitats of north-east South Africa, north to Zimbabwe, west into Botswana, the Caprivi Strip in Namibia, and southern Angola. [4] Like the other subspecies of plains zebra, it is a herbivore that exists largely on a diet of grasses, and undertakes a migration during the wet season to find ...
