Some Reflections on the Evolution of Conscious Agents: The Relevance of body Plans

The aim of this commentary article is to discuss several problems in the distribution map for conscious organisms and suggest a different strategy to address their evolutionary development. I propose to complement the model of Unlimited Associative Learning (UAL) that Jablonka and Ginsburg present in their Target Article with the additional consideration of how body plans constrain the possibilities of evolution of the brain— in some cases blocking, in some others enabling its complexification and corporal integration. In my view, the specific body plan of vertebrates has played a key role in the complexification and diversification of consciousness because it has favored an increasing integration between brain and body.
