And Sims thought that insight might help him better understand the sharks’ movements and work out how to protect the animals from fisheries. To detect a Lévy walk, researchers need to follow every move an animal makes for a considerable amount of time. “We expect the adaptation for Lévy walks to have appeared only where they confer practical advantages,” Viswanathan said. Or do Lévy walks just emerge when an animal goes searching because the world’s resources and information follow that distribution? Walking the Science ForwardThere are other lab animals that neuroscientists could monitor for Lévy walk behavior.
