The Red Queen
The term is taken from the Red Queen's race in Lewis Carroll's Through the Looking-Glass. The Red Queen said, "It takes all the running you can do, to keep in the same place." The Red Queen principle can be stated as follows:
- For an evolutionary system, continuing development is needed just to maintain its fitness relative to the systems it is co-evolving with.
The book takes Van Valen's idea, which is about co-evolution, and extends it into a discussion about sexual selection in humans. It argues that few aspects of human nature can be understood apart from sex, since human nature is a product of evolution, and evolution in our case is driven by sexual selection.
The evolution of sex [change]
Sex is an evolutionary puzzle. In most sexual species, males make up half the population, yet they bear no offspring directly and generally contribute little to the survival of offspring. In birds and mammals that idea seems less true. In human paleolithic populations, males were no doubt vital for hunting and protection. Many bird species rear the young jointly. However, most invertebrate species are not raised by parents at all, with larvae developing amongst the plankton. In addition, males and females in many vertebrate species spend resources to attract and compete for mates. Sexual selection may appear to favor traits that may reduce the fitness of an organism, such as brightly colored plumage in birds of paradise, which makes them more visible to predators. Thus, sexual reproduction appears to be highly inefficient.
The book begins with an evolutionary account of sex itself, defending the theory that sex flourishes, despite its costs, because a mixed heritage confers to each generation a defensive "head start" against parasites and disease. The basic reason for this is the way sexual reproduction increases the genetic variety in a population. This greatly increases the chance of at least some individuals surviving the onslaught of predators, parasites and diseases. This much is common ground amongst evolutionary theorists.
Ridley then argues that human intelligence is largely a result of sexual selection. He argues that human intelligence far outstrips any need for survival. He says our intelligence is like the peacock's tail, a product of sexual selection. Human intelligence, he suggests, is used primarily to attract mates through prodigious displays of wit, charm, inventiveness, and individuality. This view of intelligence is also treated at length by Geoffrey Miller. The history of ideas on sexual selection and the evolution of sex is treated by Helena Cronin.
