Final Conference ERC IDEM
Part, Process and Pregnancy
In this lecture, I use some recent work in the metaphysics of pregnancy to develop an account of biological individuality. Kingma (2018, In Press) has proposed that the fetus is a part of the mother as well as a part of the offspring, raising the more general issue of whether and when organisms share parts. Griffiths and Stotz (2018) proposed a developmental systems account of the organism according to which an organism is a process whose principle of genidentity is a life-history strategy. This lecture brings these two ideas together. To allow a more concrete treatment, I ignore all but the genetic elements of the developmental system. The central issue, I suggest, is whether the phenotype that a genetically individuated organism manifests at in some age class is an expression of the life-history strategy of that genetic individual, or the strategy of another genetic individual(s), or some compromise between these. This perspective is implicit in some existing scientific discussions of the identity of the placenta and associated structures. More generally, the question of whether some event forms part of one or more organisms turns on whether that event is under the causal control of one or more processes which implement a life-history strategy. Many events will form part of more than one life-history and as such will be ‘contested’ events whose character state represents an equilibrium in a process of evolutionary conflict. This perspective on biological individuality offers a new, and potentially quite precise, way to address questions of individuality in microbiome research.
