Suppose in this same population of turtles, a volcano erupts, spewing lava that upon cooling turns the soil surface dark and sooty. Thankfully no turtles were harmed during the eruption. However because of the change in soil color, light shelled turtles are easier to see and therefore more likely to be eaten by predators. 80% of dark shelled turtles survive predation, while only 20% of light turtles survive predation. 1. 1.0
