 One feature of organismic, physiological individuals that partially distinguishes them amongst living things is that they have life cycles that allow them to form reproductive lineages of a certain kind. The importance of life cycles for evolutionary change has been recognized both in the replicator-based view of evolutionary individuals (Dawkins 1989: ch.13) and in reproductively-centered accounts of Darwinian individuals (Godfrey-Smith 2009, 2016a). And the close relationship between being an individual organism and having a life cycle is widely accepted, being manifested in an extreme form by Griffiths and Gray’s (1994) identification of biological individuals with their life cycles within developmental systems theory.
