Darwinian individuality and symbiotic associations
Résumé
Symbiotic associations (i.e. cooperative associations of heterospecific individuals) are often highly integrated and well-defined units. Yet, because of their intrinsic heterogeneity, it is unclear whether they should be granted with any sort of ontological status in evolutionary theory. In this paper, I address the related issue of their status as Darwinian individuals. To this end, I first distinguish the notion of a Darwinian individual from the notion of a unit of selection. I then envisage whether some symbiotic associations may fall under one or both of these categories. Finally, I conclude that instances of both types can be found in nature, and provide some criteria for this category-belonging.
