Why Zebras Have Stripes Riddle Solved by UC Davis Researchers

Stream WZTV Fox 17 Newscasts LIVE starting with Fox 17 This Morning at 5am and News at 9pm.


NASHVILLE, Tenn-- We now know why zebras have stripes! Researchers  from UC Davis in California have determined the stripes are there to deter annoying horseflies and tsetse flies. 


The study, published in the Nature Communications Journal online, says research found the flies tend to avoid black-and-white surfaces so the pattern offers protection for the zebras from the blood-sucking flies which can also spread bacteria. 


Researchers did also test other popular theories and were able to rule out all but the fly-biting hypothesis. Researchers also say they found "greater striping on areas of the body in those parts of the world where there was more annoyance from biting flies."


So there you have it, the age-old riddle has finally been solved.
