Natural Selection
"Natural selection is the process where organisms that are best suited to their environment survive and pass on their genetic traits in increasing number to successive generations." (1)Turtle fossils have been found from the time of the dinosaurs, showing that turtles have been around for a long time. These structures have hardly changed throughout the years. Natural selection in turtles is not very prominent because they have not changed much. (2)
