@Chuck, as far as i know, evolutionarily, whatever qualifies as altruistic is an act that causes harm to one individual (the one acting) but benefits the group/species. Selfishness would be an act that benefits that individual, whether or not it benefits others is not taken into consideration.
There is a dichotomy because I think because many people don't understand how altruistic behaviours can be explained by evolution as the ones who behave that way are likely to die. Selfish behaviours are more easily explained.
