In one set of bottles biologically superior ova, fertilized by biologically superior sperm, were given the best possible prenatal treatment and were finally decanted as Betas, Alphas and even Alpha Pluses. In another, much more numerous set of bottles, biologically inferior ova, fertilized by biologically inferior sperm, were subjected to the Bokanovsky Process (ninety-six identical twins out of a single egg) and treated prenatally with alcohol and other protein poisons. The creatures finally decanted were almost subhuman; but they were capable of performing unskilled work and, when properly conditioned, detensioned by free and frequent access to the opposite sex, constantly distracted by gratuitous entertainment and reinforced in their good behavior patterns by daily doses of soma, would be counted on to give no trouble to their superiors. In this second half of the twentieth century we do nothing systematic about our breeding; but in our random and unregulated way we are not only over-populating our planet, we are also, it would seem, making sure that these greater numbers shall be of biologically poorer quality.
