Koinophilia

Koinophilia is an evolutionary hypothesis proposing that, during sexual selection, animals preferentially seek mates with a minimum of unusual or mutant features in functionality, appearance, and behavior. It is intended to explain the clustering of sexual organisms into distinct species and other problems described as Darwin's dilemma. The term derives from the Greek words koinos, meaning common or that which is shared, and philia, meaning fondness.
