Scientists are providing new evidence to answer the longstanding question about why zebras have stripes. It appears stripes make terrible landing strips, bamboozling the fierce blood-sucking flies that try to feast on zebras and carry deadly diseases.
Researchers on Wednesday described experiments demonstrating that horse flies have a difficult time landing on zebras while easily landing on uniformly colored horses. In one experiment, the researchers put cloth coats bearing striped patterns on horses and observed that fewer flies landed on them than when the same horses wore single-color coats.
