For years, researchers had various opinions on why the animals have those interesting stripes.
One of the most widely accepted was the black-and-white pattern was confusing to lions and helped the Zebra’s escape.
Real Clear Science reports that after further study, scientists now think the real reason is flies.
"I was amazed by our results," lead researcher Dr. Tim Caro, began. "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."
The work put together stripe pattern data on several members of the horse family and found most had more stripes if they lived in an area with heavy concentrations of biting flies.
Places like the African plains.
Studies done earlier found the irritating little biters don't often land on surfaces that are striped but the Christian Science Monitor says no one knows why.
The next obvious question is, will it work for humans?
No word on that yet but more research is ongoing for both Zebras and two-legged folks.
