Abstract
Two notorious disciplines in biology seem to be lurching toward each other, groping for mutual understanding and even fusion into a more powerful version of evolutionary biology. The two disciplines are cladistics and adaptationist theory.... The two fields obviously need each other. The current estrangement between adaptationist theory and ‘pure’ cladistics (which tends to focus on character patterns rather than on evolutionary processes) finds its metaphor in a Greek explanation of sex. Plato believed that each male and female once formed a perfect hermaphroditic whole, but through some misunderstanding (nb!) were sundered into different, individually sterile genders. As such they are condemned to wander, miserably seeking their complementary half. I would ... advise cladists and adaptationists to give up, join up, and procreate.
