A Striped Theory

Why do zebras have stripes? Many scientists came up with many theories for this unanswered question. But a new theory was formed. Scientists discovered that it might be flies... Flies? Yup, you heard me, flies. Scientists did a test. They made a fake horse and other ones with stripes and they covered the horses with super sticky stuff. The scientists let flies bite the fake horses. After testing with different kind of stripes, they discovered the one that were most like zebra stripes had the least amount of flies stuck to them. So they concluded with  the fact that zebra has stripes to not get bit by flies. But I have a lot of more unanswered questions for the scientists. Why are pandas black and white? Why do pats purr? Why do hyenas have spots? There are probably millions of questions waiting to be answered around the world.
