We present a new classification of reproducers based on Gibson's theory of affordances. First, we formalise the notion of an affordance as an action that one object in an environment can perform for another object. For example, an open door affords a person the action of passing through. Using this ontology we can classify the reproducer space according to the presence (or absence) of certain crucial reproduction machinery, e.g. a self-description. Finally, we give examples of how various reproducers can be categorised within the ontology." )))))
