I don't think this question can be answered so easily. Maybe they are the same, maybe they just don't have an appendix, or maybe they are completely zinc-based. We won't know.
I don't quite understand how the world of Heroes is supposed to be considered? From the perspective of an entire society, or of individual individuals, like Draco is talking about now?
Society consists of individuals. As banal as it sounds. And from their interaction.
Everything we can say about the world, we base on the actions of heroes (partially, of course).
Therefore, communication is an important component of society.
