Descriptive Evolutionary Ethics

Descriptive evolutionary ethics is empirical research into moral attitudes and beliefs (humans) or moral behaviour (animals) in an evolutionary framework. Examples can be found in the field of evolutionary psychology. Evolutionary psychology attempts to explain major features of psychology in terms of species-wide evolved (via natural selection) predispositions. Ethical topics addressed include altruistic behaviors, deceptive or harmful behaviors, an innate sense of fairness or unfairness, feelings of kindness or love, self-sacrifice, feelings related to competitiveness and moral punishment or retribution, moral "cheating" or hypocrisy, and inclinations for a wide variety of actions judged morally good or bad by (at least some within) a given society.

A key issue of evolutionary psychology has been how altruistic feelings and behaviors could have evolved when the process of natural selection is based on the multiplication over time only of those genes that adapt better to changes in the environment of the species. Theories addressing this have included kin selection and reciprocal altruism (both direct and indirect, and on a society-wide scale). Group selection theories have also been advanced.
