Why do scientists put a zebra suit on a regular horse? In the name of science!

In 1952, mathematician Alan Turing proved thatspots and stripes on the bodies of zebras, tigers and leopards appear due to the different speed of distribution of chemicals in the embryo. However, scientists still can not understand why these animals need stripes. They were supposed to help the zebras to mask themselves from predators and regulate body temperature, but researchers from the Universities of California and Bristol have a more realistic theory. They conducted an experiment that proved that the stripes on the body of zebras protect them from dangerous insects.

The experiment was conducted in a private stable of the city.Dundry. The researchers brought several zebras and horses of various colors on the street, and for the purity of the experiment they dressed one ordinary horse in a striped outfit. They also sprayed on her a substance that emits the smell of a zebra. With the help of several video cameras, the scientists were going to fix the insects' reaction to ordinary and striped horses.

Observations have shown that the presence of strips on the bodydoes not affect the behavior of biting horseflies. However, insects could easily land on the bodies of ordinary horses and bite them, whereas on the bodies of zebras they fell at an increased rate and did not have time to catch on. From this, scientists concluded that the striped texture effectively deceives the sight of insects, and protection is one of its main functions.

During the experiment, researchers alsofollowed the reaction of horses and zebras. It turned out that at the sight of insects, zebras are more actively trying to escape from them. It is assumed that this is due to the fact that zebras are much more likely to encounter carriers of dangerous diseases than ordinary horses.

And which of the assumptions about the function of the bands on the body of zebras do you stick to? Write your version in the comments, and you can discuss the news in more detail in our Telegram-chat.
