Chapter 38: Evolution of Cognition: A 4E Perspective

Evolution of Cognition: A 4E Perspective promotes a biogenic approach that grounds cognition in biological organization and sensorimotor coordination, asserting that even simple organisms like E. coli exhibit minimal cognition through adaptive behaviors such as chemotaxis without possessing a nervous system. A central concept introduced is the Skin-Brain Thesis (SBT), which posits that early nervous systems evolved primarily to coordinate motility across contractile body surfaces, known as Pantin surfaces, rather than merely to process sensory inputs for motor outputs. This perspective reframes the nervous system as a mechanism for managing self-organized bodily dynamics and interacting with the environment, turning the body itself into a sensing device. The text further examines how morphological features contribute to intelligence and problem-solving—illustrated by the specialized vision of New Caledonian crows or the grasping tails of seahorses—and utilizes Uexküll’s concept of the Umwelt to explain species-specific behavioral flexibility. Finally, the chapter distinguishes between Conservative Embodied Cognition (CEC) and Radical Embodied Cognitive Science (REC), advocating for the latter’s anti-representational stance regarding basic minds. It concludes by addressing evolutionary continuity, suggesting that contentful, rule-based thought is not a universal feature of animal cognition but a product of the unique human sociocultural niche.
