 Likewise, an early collection of essays on evolutionary developmental biology (“evo-devo”) by Gerd Müller and Stuart Newman (2003) focuses on how organismal form originated and on the evolutionary, developmental, and ecological processes shaping it over generations. The essays in that volume concentrate on the relationships between basic body plans of organisms over phylogenetic time, rather than the evolution of individuality as such, and do not take up The Focal Question about biological individuals at all. But like that of Maynard Smith and Szathmáry, the project of exploring these relationships is naturally expressed in terms of the concept of an organism.
