Structuralism and Selectionism: Friends or Foes? [IN PRESS]

    Research output: Contribution to journalArticlepeer-review

    Abstract

    Historically, the empirical study of phenotypic diversification has fallen into two rough camps; (1) 'structuralist approaches' focusing on developmental constraint, bias, and innovation (with evo-devo at the core); and (2) 'adaptationist approaches' focusing on adaptation, and natural selection. Whilst debates, such as that surrounding the proposed 'Extended' Evolutionary Synthesis, often juxtapose these two positions, this review focuses on the grey space in between. Specifically, here I present a novel analysis of structuralism which enables us to take a more nuanced look at the motivations behind the structuralist and adaptationist positions. This makes clear how the two approaches can conflict, and points of potential commensurability. The review clarifies (a) the value of the evo-devo approach to phenotypic diversity, but also (b) how it properly relates to other predominant approaches to the same issues in evolutionary biology more broadly.
