Historicity, Temporalities, and Causality: A Confusion at the Heart of Debates on Darwinism

If Charles Darwin’s work opened up the possibility of a true natural history, the signicance of time in evolutionary processes was left unresolved. This ambiguity has led to various interpretations of what evolutionary history is, some seeing it as the pure unfolding of processes, others as a ow marked by contingency and unpredictability. These interpretations re ect underlying differences in the perception of causality: mechanical and uniform on the one hand, transformative and multifaceted on the other. This tension affects not only our understanding of the Darwinian text, but also our contemporary conception of evolutionary theory. Although many challenges in evolutionary biology are linked to time (the historicity of evolution, path-dependent processes, biological rhythms, the contingency of certain evolutionary events etc.), the importance attributed to time in biology remains unspeci ed. The aim of this chapter is to study the contradictions regarding the conception of history and causality in Darwin’s writings and to analyse how they have permeated the different interpretations of evolutionary theory from the turn of the twentieth century to the present day. This analysis of the tensions within the different interpretations of Darwinism in history will lead me to address both the conception of biological time(s) and the approach to causality in contemporary evolutionary biology. I will conclude this chapter by proposing some clarications about the signicance of time in contemporary evolutionary biology.
