My point about aesthetics was merely to demonstrate that although we are one way, does not mean we could be another way. This applies to anatomy; for example, in the pharynx, just below the jaw, we do have two tubes. Why would the neck have to be an extra inch thick then? I don't know.
So, I think I'm missing the points that explain why we couldn't have two tubes- if you could maybe list/summarize? Appreciate it!
