Roles of mitonuclear ecology and sex in conceptualizing evolutionary fitness.
[Preprint]
Abstract
We look to mitonuclear ecology and the phenomenon of Mother’s Curse to argue that the sex of parents and offspring among populations of eukaryotic organisms, as well as the mitochondrial genome, ought to be taken into account in the conceptualization of evolutionary fitness. Subsequently, we show how characterizations of fitness considered by philosophers that do not take sex and the mitochondrial genome into account may suffer. Last, we reflect on the debate regarding the fundamentality of trait versus organism fitness and gesture at the idea that the former lies at the conceptual basis of evolutionary theory.
