Risk and Reward: Lizards Demonstrate Role of Natural Selection in Shaping Behavior

May 31, 2018
Tiny lizards in the Bahamas are providing scientists with new insights into evolution in isolated environments. In a new paper in the journal Science, biologists analyzed the risk-taking actions of the brown anole (Anolis sagrei) to better understand how animal behavior is influenced by natural selection.
