There's a wide population of turtles. Some turtles have webbed feet, and some don't.
The turtles with webbed feet have a favorable trait because they outrun predators better than the turtles without webbed feet.
Not having webbed feet means the turtles can’t swim as fast and they get eaten.
Over time, the turtles without webbed feet mostly get eaten by predators.
Over time, the turtles with webbed feet survive, reproduce, and pass along their traits to their turtle babies.
After a while, most of the turtles in this population have webbed feet.
