Elimination

Random Foolish Question of the Day:

Creationist typically criticize "natural selection" by claiming the mechanism to trigger "change" is absent.

I think this is a valid argument.

But what if natural selection works the other way around?

Attrition/elimination of those things/organisms that DON'T have an attribute, thus leaving the gene pool filled with those that do. The stronger the characteristic, the more that gene or trait is emphasized. Maybe the 'change' is simply the change in the environment. That change is well documented (ice ages, volcanoes, meteors).

I have not researched this angle at all, so don't throw arguments my way.
