Scientists solve why zebras have stripes

new study has revealed the strongest evidence yet that the stripes help to deter biting insects.
The precise purpose of a zebra's stripes had remained something of a mystery for years with some of the more common theories ranging from providing camouflage to reducing body temperature.

The answer, as it turns out, is that the stripes on a zebra, like on several other animals, serve to help keep away biting insects. By analyzing and comparing a number of factors pertaining to each of the most popular hypotheses, researchers were able to rule out the facts that didn't fit and identify those that did, such as the discovery that most of the species that do possess stripes like those of a zebra tend to live in countries where biting flies most commonly prove to be a problem.
