|Features, philosophy: Features are fundamentally characteristics, however in the philosophical terminology according to Frege it has become natural to speak of (necessary) characteristics, but in objects of (contingent) properties. Objects do not have their properties necessarily, they can always be different. Concepts, on the other hand, have their characteristics necessarily. E.g. that circles are round is a necessary characteristic of the concept circle, but not a necessary property of drawn circles. It is, however, not the concept which has the characteristic itself, but the objects which fall under it.|

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.
