If females choose physically attractive males, they will tend to get physically attractive sons, and, thus more grandchildren, because other choosy females will prefer their attractive, sexy sons. Ronald Fisher's principle, as published in his book The Genetical Theory of Natural Selection, is one of several possible explanations for the highly diverse and often astonishing ornaments of animals. The result of this is that one of the most desirable qualities a male can have in the eyes of a female is, quite simply, sexual attractiveness itself. If she can ensure that her son is one of the fortunate few males who wins most of the copulations in the society when he grows up, she will have an enormous number of grandchildren. In a society where males compete with each other to be chosen as he-men by females, one of the best things a mother can do for her genes is to make a son who will turn out in his turn to be an attractive he-man. In 1976, prior to Weatherhead and Robertson's paper, Richard Dawkins had written in his book The Selfish Gene: So that in selecting a mate from a number of different competitors, it is important to select that one which is most likely to produce successful children. The first step to a solution lies in the fact that the success of an animal in the struggle for existence is not measured only by the number of offspring which it produces and rears, but also by the probable success of these offspring. Granted that while this taste and preference prevails among the females of the species, the males will grow more and more elaborate and beautiful tail feathers, the question must be answered "Why have the females this taste? Of what use is it to the species that they should select this seemingly useless ornament?" Female mating preferences are widely recognized as being responsible for the rapid and divergent evolution of male secondary sex characteristics.
