The thermal limits of natural selection.

[Fiery Diamond]

It's less that you do not believe in entropy and more that you do not seem to understand entropy and optics.

If you think that natural selection can be derived from thermodynamics, show something more concrete. Otherwise there is not much to discuss.

Also, it might just be a language detail, but entropy is not something to believe in - no concept in science is.

To "believe in" something has multiple different meanings. One of them is "believe that [something] is true/real." With that meaning, yes, someone can believe in or not believe in a scientific concept.
