A very interesting paper has been published by Brenda Larison and her colleagues in the Royal Society Open Science Journal to answer common and frequent questions:
Why Zebras has got stripes? Why are their role?
Many explanations have been suggested, including social cohesion, thermoregulation, predation evasion and avoidance of biting flies. Identifying the associations between phenotypic and environmental factors is essential for testing these hypotheses and substantiating existing experimental evidence.
In contrast to recent findings, we found no evidence that striping may have evolved to escape predators or avoid biting flies. Instead, we found that temperature successfully predicts a substantial amount of the stripe pattern variation observed in plains zebra.
