Their flights were not random. Instead, they matched a mathematical algorithm for a pattern called the Lévy distribution. This search pattern is an effective way to find food, a method also known to be used by albatrosses, monkeys, and deer, and the flies made reasonable, not random, choices, too. Scientists have found similar patterns in human behavior, in the flow of e-mails, letters, and money (and, Brembs observed, in the paintings of Jackson Pollock).
