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.

"We found again and again and again [that] the only factor which is highly associated with striping is to ban biting flies," said study leader Tim Caro. "I was delighted to see the results were so strong in one direction."
