- Gary has noticed his friends who were slow and clumsy were being eaten by lions. Gary seemed to have stronger leg muscles and and could outrun the lions. Because Gary was the fastest out of all of his friends, he and all of his other fast friends, were able to avoid being killed by lions. Gary grew up and was able to have offspring, passing down his speed to another generation.
