Between the earliest proto-organisms and modern complex animals, evolution has produced hugely varied physical forms, physical behaviours, life-cycles, and modes of reproduction. All use information of various kinds (along with matter and energy). Information contents control internal and external processes: including changes through learning and development of individuals, and in genome development by evolution. Information contents are also involved in social and cultural changes. I conjecture that animal intelligence involves far more diversity in forms of information-processing than we have dreamed of so far, and that the sources of that diversity lie in various layers of complexity in the physical, biological, and social environments in which evolution and individual development occur. Contrary to common assumptions about embodiment, some of the more abstract features of the environment (e.g. rigidity and diversity of 3-D terrain structures) can have a common influence on evolution of information-processing in animals with very different neural mechanisms, sensory and motor systems and morphology, though implementations of the common functionality differ. The ontologies currently used for observation and theory-construction by most neuroscientists, psychologists, biologists, and AI/Robotics researchers cannot accommodate all of those features, seriously restricting the explanatory power of theories using current ontologies. I shall address some ways of overcoming those limitations, in part by illustrating environmental features that have received insufficient attention, and in part by decomposing some of the functions of a genome.
