You seem to have fixated on one word in my comment and are arguing against creationism. I'm not saying that evolution makes no predictions, I'm saying that saying "oh yes, everything is the way it is because it confers an evolutionary advantage" is a mostly wrong, largely useless answer.

Well, I would argue that the vibe of your whole comment was coherent in that sense: you talked about what nature wanted, about design and about what kind of stuff would make sense while looking at it from a architect perspective.
It's a very odd way to look at it if you have no creationist conception of it all to be honest.
As for your point that not everything has an evolutionary advantage, I agree. Deafness and blindness exist after all.
But I don't really see your point as far as proposing hypotheses to account for certain prevalent traits, which, in my opinion, is what the original content was about (the grandmother hypothesis).
