Some used to think that the stripes were a form of camouflage, a theory criticized by Charles Darwin due to the fact that zebras prefer open savannahs, rather than heavily forested areas. A new study performed by an international team of researchers suggests that the zebra's stripes are actually an advanced form of fly repellent. Leading a team of colleagues, Dr. Gabor Horvath of Eotvos University in Budapest conducted a series of studies with horse-shaped models, some of which were painted uniformly dark, some painted uniformly white, and some with stripes of various widths. They were looking to see if horseflies would prefer a certain object, and as it turns out, the least attractive of these items were the ones with the stripes that most closely resembled those found on zebra hides. The reasons for this selection remain unclear, but Horvath has speculated that it might be due to the fact that horseflies have a difficult time seeing polarized light. As such, the horseflies might confuse the small animals, and make it difficult to see the zebras.
