Biology and the moral paradoxes

Considerations from biology suggest (1) that human interests can be generalized as reproductive, involving activities by individuals that tend to promote the survival of their individualized sets of genes; (2) that ethical, moral and legal questions arise out of conflicts of interest that exist because of our history of genetic differences; (3) that human behavior probably always involves egoistic tendencies and moral inconsistency; (4) that the stages of moral development described by social scientists correspond to the patterns of life effort discussed by biologists;(5) that the idealized moral systems of philosophy and religion have been developed as models that are promoted in others but not (or more than) in one's self; and (6)that what are usually seen as the closest approaches to these idealized models are the sources of our most severe problems because they involve between-group competition and strife.
