> Competition would be if a body part actively attacked another body part.

I guess we'll just have to agree to disagree about this. I don't see a lot of daylight between "active attack" and starvation of resources. Just because your attacker chooses to lay siege to you rather than mount a full frontal assault doesn't make them any less of an attacker IMHO.

> The "edges" as thoroughly defined in the paper I linked.

Sorry, I don't see it. AFAICT the word "edges" only appears once in the paper:

"Evolution is a process of continuous change, and so we should expect blurry edges with a mosaic of features (1)."

[UPDATE] Oh, BTW, I think that paper is actually very good. Thanks for bringing it to my attention.
