Ever Wondered Why Zebra's Have Stripes...

Ever wondered why zebras have black-and-white stripes? Well here is the explanation why...
Well, a group of scientists think they developed them to keep away blood-sucking flies. As strange as this may sound, but this is all true....
Researchers put out different coloured models of horses in a field - one brown, one black, one white, and one with black-and-white stripes.
The model with black-and-white stripes attracted the least number of
flies.
The team thinks the stripey pattern is a turn-off for flies, because of how it reflects light.
There have been loads of ideas about why zebras have stripes. Some scientists think it's to confuse predators when they're in a group. Another theory is that zebras use the stripes to recognise each other!
