- Prairie dogs exhibit a behavior that appears to be contrary to that of natural selection. One will act as a lookout for the others of the community, demonstrating a warning call when observing an eagle flying overhead. This loud noise calls attention to himself which puts him more in harms way than if he ran to hide discretely. However, the warning call allows the others of his community to react and protect themselves.
