 The relationship between evolution and development has been a long debated topic in the history of biology and philosophy of biology. This entry has sampled a small portion of work relevant to the conceptual, epistemological, anthropological and ethical reflections on this relationship. Besides the issues discussed here, philosophers of biology and biologists have discussed how developmental and phylogenetic approaches to homology can be integrated (Amundson 2004; Wagner 2014; DiFrisco 2019; see the entry  developmental biology),  what model organisms (Love 2009; Lloyd et al. 2012; Minelli &amp; Baedke 2014; Zuk et al. 2014; see entry  developmental biology)  and representational tools scientists (should) use for studying relationships between evolution and development (e.g., normal plates, cell fate maps, epigenetic landscapes) and what the epistemic and heuristic roles of these tools in scientific practice are (see Haraway 1976; Gilbert 1991; Hopwood 2007; Love 2010; Baedke 2013; Baedke &amp; Schöttler 2017; Nicoglou 2018). In addition, long standing debates on teleology in biology (see the entry  teleological notions in biology)  drew on the relation between evolution and development to distinguish the teleological dimension of development from non-teleological evolutionary processes (Mayr 1961), to introduce new conceptual frameworks, like teleonomy, which refer to only apparently purposeful systems (Pittendrigh 1958), or to highlight the purposeful acting organismic agent as a starting point to reason about the teleological nature of evolution (Russell 1950; Piaget 1976 [1978]; Walsh 2015).
