For Tim Caro, it was surprisingly easy to dress horses like zebras. Why zebras have stripes: Black and white pattern 'dazzles' blood-sucking flies and makes it harder for them to land on the animal's skin.
Blocking Immune System Pathway May Stop COVID-19 Infection, Prevent Severe Organ Damage While the world waits eagerly for a safe and effective vaccine to prevent…. Caro’s team is now planning to test this hypothesis, and others.

People are still not sure whether the zebra stripes worked well for ships, but they seem to work well for zebras. Not only did the insects land on the zebras less often, they didn’t stay long once they landed. So wondrous, in fact, that many people have imagined it to be evidence of God’s infinitely artistic hand. But that can’t be true: Amanda Melin of the University of Calgary recently showed that lions and hyenas can’t even make out the stripes unless they get very close.
Now a group of scientists working in the UK have used a creative experiment to help explain how stripes help zebras – by confusing the insects, making it hard for them to land on zebras in the first place.
Zebras are famous for their strong pattern of black and white stripes. All Rights Reserved. The researchers plan to test their thermoregulation hypothesis, either by studying the behavior of air currents over zebra pelts, or by implanting wild zebras with temperature sensors, if they are granted permission to do so, Larison said.

From far away, the zebras may look solid gray, so the flies zoom in fast, feeling sure of where they are going. Other animals have predators, and they don't have stripes,'" said study co-author Ren Larison, a researcher in the Department of Ecology and Evolutionary Biology at UCLA. What do you do if a zebra escapes from the zoo?
Instead, mounting evidence suggests that it is parasitic flies that are confounded by the zebra’s distinctive patterning.

Although both males and female zebras are similarly striped, Darwin hedged that “he who attributes the white and dark vertical stripes on the flanks of various antelopes to sexual selection, will probably extend the same view to the … beautiful zebra.” In other words, the stripes help males and females make sensible choices about whom they mate with.
Caro, a biologist at the University of California at Davis, has spent years thinking about why zebras are striped, and has even written a book about this mystery. "An additional cooling mechanism could be very useful under these circumstances.".
