Principle #1: Genetic Variation The genetic variation in the Leatherback Sea Turtles is that there are some that have strong fins, and others who have weaker fins.
Principle #2: Overproduction and the struggle of existence Sea turtles lay more than 100 eggs, but not many survive. because so many hatch, they are very noticeable to their predators. Those with strong flippers have a better chance of surviving and reproducing.
Principal #3: Differential survival and Reproduction The sea turtles with weaker flippers have a higher chance of getting eaten by their predators because they can't swim very fast or far from their predators.
Principal #3: differential survival and Reproduction Those with the strong flippers have a better chance of surviving because they can dive deep into the ocean and escape from predators.
Principal #4: changes in Gene Pool Since the turtles with the the strong fins can swim fast into the water, they have a better chance of survival resulting in an Increase of sea turtles with strong fins, and a decrease in the sea turtles with weak fins.
That's Natural Selection in Leatherback Sea Turtles!
