The Biological and Evolutionist Bases of Ethics

Abstract

A rational and naturalistic definition of ethical norms must stipulate the preservation of the DNA typical of the species and the maintemance of its intra specific variability. Indeed, this aim of preserving the DNA of the species and preserving its intra specific variability is the basic principle of bioethics. The historically limited behaviour can be related to morality which can assume different norms in different historical contexts. Morality could therefore be governed by religious or normalised by discipline. Ethics instead a pure biological and ecological discipline.
