Evolutionary Ethics in the Light of Extended Synthesis
Abstract
The program of Evolutionary Ethics (EE) is based on the assumption that our moral features constitute adaptations and as such are to be explained in terms of the evolutionary process of natural selection. However, the fundamental assumption of EE was seriously put into question: the level of analysis relevant for moral features is essentially ontogeny and culture, while the explanation using natural selection applies to the level of phylogeny and genes (Sober, 1995; Ayala, 1995; Okasha, 2009). To the discussion on the validity of the program of EE we propose to bring the recent program of Extended Synthesis (ES, Pigliucci & Muller, 2010), because it attempts to account for the role of the ontogeny in evolution. We conclude, nevertheless, that ES fails to properly account for the importance of ontogeny in evolutionary processes because by extending the notion of inheritance it (con-)fuses the notions of unit of inheritance and of unit of selection (against the well-known distinction made by Hull, 1980).
