The secret of Why Zebra has Stripes

We all know that the Zebra has black stripes on its white skin. Have you ever wonder why?? Science has discovered recently the purpose of those stripes. There are certain type of dangerous flies who bites the animals and this leads to several dangerous diseases in them. There was an experiment in which the statues of Zebra were painted Grey, White, Black, White and Black etc. The flies were left open to sit on them and there were just a little flies who sat on Black and White (the original colour of Zebra). Rest which were greater in number, sat on other colours and scientists made the conclusion that the purpose of these stripes are to save Zebras from those dangerous and harmful flies.
