Hurricanes twist evolution in island lizards

UNIVERSITY PARK, Pa. — A good grip can mean the difference between life and death for lizards in a hurricane, causing populations hit more frequently by hurricanes to have larger toepads, according to researchers from Washington University and Penn State.
Lizard groups that experience more hurricanes evolve larger toepads than those that experience fewer hurricanes, according to analysis spanning 12 island populations of Anolis sagrei lizards and a separate analysis of 188 Anolis species ranging from Florida to Brazil.
