Overview

altruism


Show Summary Details

Quick Reference

Sacrifice, if necessary of life itself, so that others, commonly offspring or otherwise genetically close younger relatives, may survive or otherwise benefit. On the face of it this seems to reduce the adaptive value of the altruist. However, by saving offspring at the cost of its own life, the altruist may ‘save’ more of its own genes than if the situation were reversed, particularly if the reproductive potential of the altruist is exhausted, or nearly so.
