KOINOPHILIA Meaning and
Definition
-
Koinophilia refers to a theory in evolutionary biology that suggests organisms prefer or are attracted to average or common features in their potential mates, thereby avoiding extremes. The term "koinophilia" is derived from the Greek word "koinos," meaning common, and "philia," meaning love or attraction. This phenomenon proposes that individuals of a species are more likely to choose mates with average or typical characteristics, instead of those with unique or extreme traits.
The concept of koinophilia is based on the idea that individuals with average or common features possess a lower number of mutations or genetic abnormalities, indicating a higher level of genetic fitness and health. Therefore, by selecting mates with average characteristics, organisms increase their chances of producing healthy and highly adaptive offspring.
Koinophilia can be observed in various traits, such as facial symmetry, body size, coloration, and other physical features. For instance, in many species, individuals with average facial symmetry are considered more attractive, as they are believed to possess better overall health and genetic quality.
This theory also suggests that koinophilia may play a role in the maintenance of general species characteristics over time, as the preference for average characteristics prevents extreme variations from becoming prevalent in a population.
Overall, koinophilia represents a preference for common or average traits in mate selection, driven by the desire to find genetically fit partners and produce healthy offspring.
Etymology of KOINOPHILIA
The word "koinophilia" is a combination of two Greek words: "koinos", meaning common or general, and "philia", meaning love or affinity. The term was coined by British psychologist Timothy Perriam in the late 20th century to describe a psychological preference or attraction toward common or average characteristics rather than extreme or unusual ones.
