Darwin- would he have changed his theory?

I'm fairly sure we know the functions of at least most of the proteins in the human body, or in any body.

I'd have to partially, at least, disagree. We likely know one or two sort of obvious functions for a large number of proteins in our bodies, but that is liable to be only a tiny fraction of all the various things some of them do. And I would be surprised if we have any more than a description like "olfactory receptor" for the majority of the 25,000(??) proteins our bodies make.

We're quite a ways from Frankenstein.

Gotcha......so, we haven't really decoded the code of life, whatever that may be called...

You haven't "got" anyone. If we had The Whole Enchilada figured out, all those molecular biologists would be asking "Would you like fries with that?" Instead, they're busily trying to find out things - science does that, y'know.

Nosy likes a lively discussion as much as the next old guy. He's merely trying to enforce the rules.
