The Zebra He found a suitcase to avoid Horsepower, Covered with strips, a trick that would work in humans, according to a study published in the journal this morning. Royal Society of Open Science.
Zebra's pressure is fascinating for scientists for centuries, and there are many hypotheses to explain the evolution of the animal, as it would serve to blend into the savannah shadows and its vegetation, control its temperature. .
Different assumptions, US, are still being studied. There. Researchers found in 2014 that if the zebra came up with strips, it would protect its species from the bites of the fly and the horsepower.
At the Gabor Horvath discovery, a researcher at the Eotow University in Budapest, hypothesized that the white bands with which some communities in New Guinea, Papua, Africa and Australia are sometimes covered may have a similar effect.
The researcher and his team then expand their bloodthirsty insects to three human plastic mannequins "visually equivalent to living models": one dark brown, one dark brown, with white stripes and one final colorless one.
The researcher considers that it is not necessary to expose humans to the bites because "when the horse games choose their targets, the most important are the visual references."
After several weeks of exposure, "our brown man model is 10 times more attractive to horsepower than the brown model with white stripes," the researcher told AFP, adding: "The beige model, which served as a witness, was twice. To the headbands when the brown striped pattern ".
The "antitank" effect would not apply only to white stripes, but to any type of motif. According to the researchers, they reduce the polarization of light reflected by the human body, making it less "appetizing" for horsepower. The finer and more repetitive the motive, the more effective it becomes.
For the researcher, although people who take painting in their bodies do not protect themselves from stings, but for social and cultural reasons, there is "an example of nature evolution and adaptation to the environment"; Because of the paintings reduce the risk of transmission of pathogenic agents and dangerous diseases.
