This is one of those moments that I pass over a statement in total agreement, not needing to comment; and then something catches my attention. Why the word "style" and the word "arc"? Can you identify non-biological styles? And is an arc kind of like a paradigm? A choice of words can drop the hint that there's a whole new point of view behind the vocabulary, like when you came up with "schema bendae."

Or, maybe I'm reading too much between the lines.
