Consider, for instance, the dependence of the honey bee and her hive on the functions, every one instinctive, of queen, workers, and drones. There is the queen, whose sole work is to lay eggs; the drones, or males, whose function it is to fertilize the queen; and the workers, which are females undeveloped sexually. In these three kinds of individuals we see a combination of many most remarkable instincts and peculiarities of structure which look to the good of the community. How could they have been produced by evolution? The workers are sterile and leave no offspring, consequently their instincts cannot be inherited from bees of their own class. Each generation of workers is isolated from all succeeding generations. A colony of bees is not like a community of civilized human beings in whom many of the wants are artificial, and which may remain unsupplied, with simply a certain amount of discomfort, but the wants which the instincts of bees supply are imperative, and, therefore, the instincts themselves, as a whole, are necessary to the existence of the bees. Their instincts are all linked together as a necessary chain, so that if one should fail the community would perish. Each kind of work is perfectly done, and yet the workers are totally unconscious as to what will be the result of their labors. For the most part they work for future generations of their colony, and not for themselves, and yet they are as careful and diligent as if they were guided by the highest intelligence and the most selfish motives [tr. note: sic no punctuation]. Fairhurst, whom we are quoting, adds: "There is nothing more wonderful and mysterious in nature than the instincts of bees. What can be more remarkable than that instinct of the workers which causes them to prevent the queen from stinging to death the young queens in their cells? Here we see the instinct of the workers opposing that of the queen, and thus saving the colony and insuring the propagation of the species. And yet at other but proper times the workers permit the old queen to kill the young ones in their cells. How could these instincts in the workers, which act in exactly opposite ways by just the right times for the welfare of the community, have ever been evolved? Or how could that instinct have arisen which causes two queens when engaged in combat to refrain from inflicting the mortal sting if they would mutually destroy each other, and thus leave the hive without a queen?--acting as if they knew that the life of one of them was necessary for the welfare of the community."
