Why do zebras have unique black and white stripes?
This is a question that many scientists have been asking since the British naturalist Charles Darwin set out his perspective on evolution in the mid-nineteenth century
. the most convincing arguments were that their stripes may have an evolutionary purpose that keeps animals cool in hot weather.
But now, a group of researchers in Sweden says that they have debunked this theory by saying that the temperature has nothing to do with
They believe that the black and white fur of the zebra works as an "optical protection" against insects – such as haematophagous horsefly

The logic behind the theory of temperature is that in hot weather the black band becomes warmer than the white areas, creating small vortices when Warm air above the dark fur meets the colder air above the white fur that works as a fan to cool the body.
with water and covered with different colors imitating the fur of species belonging to the equus family (horses): black and white stripes, black, white, brown and gray.
They then placed the barrels in the sun and then measured the temperature in each barrel.
Black was the warmest while white emerged coldest. The temperatures in the striped and gray barrels were similar, but not significantly lower.
