Researchers Discover Why Zebras Have Stripes
Short Video at Link, but here is the written story:
It's an evolutionary abnormality that has stumped scientists for hundreds of years: Why do zebras have stripes?

“No one knew why zebras have such striking coloration,” wrote Tim Caro, lead author and a UC Davis professor of wildlife biology, in a press release. “But solving evolutionary conundrums increases our knowledge of the natural world and may spark greater commitment to conserving it.”
The biting fly explanation has long been suspected, as flies tend to avoid black-and-white striped surfaces. To find out once and for all, researchers noted the geographic distribution of zebras, horses and asses, and noted differences in zebra stripe patterns. They then overlapped the data with variables such as temperature, terrain, predator range and biting fly distribution.
While the other factors did not correlate with stripe patterns, one factor overwhelmingly did: the biting flies.
“I was amazed by our results,” wrote Caro. "Again and again, there was greater striping on areas of the body in those parts of the world where there was more annoyance from biting flies.”

However, as researchers mentioned in the release, one mystery solved leads to yet another mystery: why biting flies avoid black-and-white striped surfaces.
