This is the story of Ryder experiencing natural selection.
This is a story of Ryder the sea turtle, along with many others, and how they experienced natural selection.
Sea turtles lay over 100 eggs, but not all of them survive. When predators approach, not all of the sea turtles are able to escape. Those with strong flippers have a better chance of surviving and then reproducing.
Those sea turtles with weaker flippers have a high chance of getting eaten by their predators, in this case a shark, because they cannot swim very fast or far.
Because Ryder and the sea turtles with strong flippers can swim faster in water, they have a better chance of survival. This results in an increase of sea turtles with strong flippers and a decrease of sea turtles with weak flippers.
This is an example of directional selection, which is a mode of natural selection. The phenotype of strong slippers is favored over the other phenotypes. Through this directional selection, the species of sea turtles with weak flippers started to disappear.
Therefore, the sea turtles with strong flippers were the ones that survived and made it safely to land. Natural selection is what produces evolutionary change. In this situation, Ryder is able to reproduce and continue evolution by producing offspring sea turtles with strong flippers so that they can survive in their environment.
