The document discusses the concept of "co-ontogenic drift", which refers to the natural process of change that occurs when a system interacts with and is influenced by its environment and other systems. It provides examples of how co-ontogenic drift can occur through social interactions and learning experiences where students and teachers mutually influence each other. Deep learning involves structural changes in networks of relationships that allow for open communication and the emergence of new understandings through a process of co-creation between learner and environment.
