Both the SPT of Troncale, and Wilson’s notes agree that “Information” has representation on all scalar levels, not just the human. We may call it “information” but the other levels also exchange vital aspects of themselves among each other. Just because we call it information on the human level, should not obscure the similarities of the process whatever scalar level or between whatever the dominant or local components are on the level being examined.
You will also find using search that information is mentioned in many of his notebooks.
