Abstract
When individuals have the opportunity to invest in offspring or siblings who are equally closely related and helpless, they should invest in offspring. Two reasons are proposed. Both depend ultimately on the fact that if Ego invests in kin other individuals may not behave in Ego's best interest. 1980 Blackwell Verlag GmbH
