Introducing Computational Evo Devo

Show Summary Details


This chapter presents a framework for understanding the evolution of cognition and, specifically, of computational systems. The chapter adheres to a particular view on Evo Devo which, combining proposals from Complex Dynamic Systems Theory, Developmental Systems Theory, and crucially, the concept of Morphological Evolution, explains the development/evolution of phenotypes as trajectories leading to particular points within a discontinuous space of possibilities (“morphospace”) constrained by a number of parametric factors. The chapter further contends that the Chomsky Hierarchy, measuring the relative complexity of different types of “languages” (in the technical sense of Formal Language Theory), can be directly translated into a “computational morphospace,” the parametric factors of which describe the system underlying the development of the organ presented in the previous chapter.

Keywords: evolution; development; morphospaces; heterochrony; developmental constraints; brain evolution
