 A third ontological point concerns the exact nature of the link between development and evolution. Two approaches have been put forward: One draws on the idea that the biological entity that is causally efficacious in both realms can only be found on the level of integrated collectives of symbiotic interactions. Following in the tradition of Leibnitz’ notion of compossibility as well as Margulis’ (1999) claim that we live on a ‘symbiotic planet,’ this view argues that symbiotic collectives are not only essential units of development but also of evolution. This leads to a view of evolution that is not centered on interspecies conflict and competition between individuals (Huxley 1888; Williams 1966; Dawkins 1976). Instead the entities that evolve are cooperative co-developing collectives (Rosenberg &amp; Zilber-Rosenberg 2016; Roughgarden et al. 2018; for discussion, see Peacock 2011; Suárez 2018).
