"The tulip’s genetic variability has in fact given nature—or, more precisely, natural selection—a great deal to play with. From among the chance mutations thrown out by a flower, nature preserve the rare ones that confer some advantage—brighter color, more perfect symmetry, whatever. For millions of years such features were selected, in effect, by the tulip’s pollinators—that is, insects—until the Turks came along and began to cast their own votes.… Darwin called such a process artificial, as opposed to natural, selection, but from the flower’s point of view, this is a distinction without a difference: individual plants in which a trait desired by either bees or Turks occurred wound up with more offspring. Though we self-importantly regard domestication as something people have done to plants, it is at the same time a strategy by which the plants have exploited us and our desires—even our most idiosyncratic notions of beauty—to advance their own interests. Depending on the environment in which a species finds itself, different adaptations will avail. Mutations that nature would have rejected out of hand in the wild sometimes prove to be brilliant adaptations in an environment that's been shaped by human desire."
