Feature/Phenotype/Gene/Dawkins: any feature such as e.g. a green beard is merely a method by which a gene can "recognize" copies of itself in other individuals.
Feature/Altruism/Dawkins: according to the thesis that genes try to help copies of themselves in the bodies of others, features are developed.
Perhaps a gene for altruism can thus be recognized in altruistic behavior?
In fact, relationships are recognized in behavior. For example, the parents' selflessness towards their offspring.
