There are three species of zebra; the more common plains zebra, and the endangered Grévy's and mountain zebras. They evolved alongside other horses in the Americas around 4 million years ago. Mostly social animals, zebras live in "harems" which can sometimes aggregate into larger herds.
Like human fingerprints, zebra stripes are unique to each individual. Previously believed to be black stripes on a white animal, we now know that zebra's are black with white stripes.
The actual function of the stripes has been hotly debated. Some think that the dazzling stripes may confuse predators or that they are helpful in individual or species identification. Sir David Attenborough, in David Attenborough's Natural Curiosities wonders whether they are in fact for confusing biting flies, limiting the spread of disease. Either way, they are probably an adaptation driven by a number of different reasons.
Unlike horses and asses, zebras have always proved difficult to domesticate. Attempts have been made to train zebras for riding, while Lord Rothschild managed to train his zebras to draw a carriage and Queen Charlotte tried to cross hers with a donkey.
