- Koinophilia abstract "Koinophilia, a term first used by biologist Johan Koeslag, is when sexual creatures seek a mate, they prefer that mate not to have any unusual, peculiar or deviant features.Natural selection results, over the course of generations, in beneficial (or "fit") features replacing their disadvantageous counterparts. Thus, natural selection causes beneficial features to become increasingly more common with each generation, while the disadvantageous features become increasingly rare. A sexual creature, therefore, wishing to mate with a fit partner, would be expected to avoid individuals sporting unusual features, while being especially attracted to those individuals displaying a predominance of common or average features. This is termed "koinophilia". It has, as an important side effect, that mates displaying mutant features (the result of a genetic mutation) are also avoided. This, in itself, is also advantageous, because the vast majority of mutations that manifest themselves as changes in appearance, functionality or behavior, are disadvantageous. Because it is impossible to judge whether a new mutation is beneficial or not, koinophilic creatures will avoid them all with equal determination, even if this means avoiding the very occasional beneficial mutation. Thus, koinophilia, although not perfect or infallible in its ability to distinguish fit from unfit mates, remains, on average, a very good strategy when choosing a mate. It will be right far more often than it will be wrong. Even when it is wrong, a koinophilic choice always ensures that the offspring will inherit a suite of thoroughly tried and tested features.Koinophilia must be distinguished from assortative mating, which means “like prefers like”. If like prefers like it would mean that leucistic animals (such as the white peacock in the illustration), for instance, would be sexually attracted to one another. Since leucism is not an excessively rare mutation, a leucistic subspecies would rapidly come into being, as would similar variations of the parent species. Koinophilia predicts that this is unlikely to occur because a leucistic animal is attracted to the population average in the same way that all the other members of the species are attracted to that average. But none of the other members of the species are attracted to the leucistic individual, because of its unusual appearance. Few leucistic individuals therefore find mates. This means that they are very unlikely to form leucistic lineages that might lead to the creation of a new subspecies, or species, except, possibly, where they have a major advantage over alternative colorings in snow covered landscapes, where they might readily become a majority in a very low density population. According to Koeslag, koinophilia provides very simple and obvious explanations for such evolutionary puzzles as the process of speciation, evolutionary stasis and punctuated equilibria, and the evolution of cooperation. Koinophilia might also contribute, possibly substantially, to the maintenance of sexual reproduction, preventing its reversion to the much simpler and inherently more advantageous asexual form of reproduction.".
