Beyond the sea squirt’s brain: cognition as inseparable from sensory-motor action

Coombs and Trestman offer a cogent and biologically-grounded framework in which cognitive evolution is linked to the evolution of bodies and sensory-motor mechanisms. We are strongly supportive of such an endeavour, but argue that sensory-motor adaptations should rightly be seen as part and parcel of cognition itself and not simply as the foundation for cognitive evolution.
