 Many ontological debates on the relation between development and evolution focus on the organism as the central unit, which both develops and evolves, in contrast to, for example, genes or populations. Several theories have tried to clarify the nature of this organismic unit: According to one influential view, the organism is a series of integrated processes during a life cycle (Bonner 1965; Nicholson &amp; Dupré 2018; Fusco 2019a; DiFrisco 2019), with complex and reciprocal relationships between the whole organism and its parts (Gilbert &amp; Sarkar 2000; Esposito 2016; Peterson 2017). Central elements of this view are based on an organicist framework developed by Kant, which states that in organisms “the parts, with respect to both form and being, are only possible through their relationship to the whole” and “that the parts bind themselves mutually into the unity of a whole in such a way that they are mutually cause and effect of one another” (Kant 1790/1793 [1902: 373]; see also Lenoir 1982). Haraway (2008) highlights the latter idea of reciprocal interaction between organisms’ parts by saying: “Reciprocal induction is the name of the game” (2008: 228) and it is “reciprocating complexity all the way down” (2008: 42).
