Why zebres have stripes

The scientist studies have shown us that zebres have unmistakable stripe because general reasons.
One of this is because catch zebre has am unique pattern, and then it's different to the others; and the others animals can recognize it.
Another one reasons is that the zebres with their stripes are camuflage in a vast herd and the predators can not see them.
The most important reasons can be that zebres with their striped pattern; are animals much less atracttive to insects. 
Scientists in a experiment could see that in a fly-infested field, the flies in front of black, or white horse, or zebra-striped landed less over the model zebra.
The researchers think that zebras had black-coated, and enolved its with stripes.
