Isn't reproduction -- not life -- the standard of value?

In "The Objectivist Ethics," Ayn Rand claims that "an organism’s life is its standard of value," meaning that "that which furthers its life is the good, that which threatens it is the evil." She claims that on the grounds that the physical functions of a living organism are "actions generated by the organism itself and directed to a single goal: the maintenance of the organism’s life." In fact, however, evolutionary theory teaches us that reproduction, not life, is the ultimate end of every living organism. Is that true? If so, does that have implications for ethics?
