London : The characteristic black and white striped fur of zebras do not help the animals stay cool in the hot sun, according to a study that refutes a belief that dates back to Darwin. Ongoing discussion among researchers on why zebras have their signature black and white stripes suggests that it keeps them cool in the sunshine The black stripes get warmer than the white areas, and the theory states that this creates small vortexes when the hotter air above the dark fur meets the cooler air above the white fur.

Eight years ago she and her colleagues from Hungary and Spain presented another theory, where they claim that bright fur works as an optical protection against blood-sucking horseflies and other insects that bite. Horseflies are attracted by polarised light, the sort of light that appears when sunbeams are reflected on a dark surface.
