Yes, Dave, biological evolution only takes place in ... biological beings that have ... biological elements like genes.But you are restricting evolution to ONLY the biological elements and molecular structures, TOTALLY IGNORING the fact that for those organic molecules to recombine and reproduce the aid and assistance of the atomic basis of life is required.
Glaciers don't do it. Rainbows, nope. Mountains, nope. Magnetic field lines...nope.
And, yes, for organic chemistry to work, you're right, atoms need to work as they do - as we observe them doing. If atoms did anything else - let's say Carbon only had 1 binding site - then life as we know it would not work.
Sorry, baby, your weak protest here, which is really just an observation akin to the anthropic principle, doesn't mean that carbon atoms evolve. They don't. Carbon atoms remain carbon atoms no matter what organic molecule they're in, no matter how many times they've been in an organic molecule, no matter how many times they've been digested, pooped, breathed, farted, whatever.
It's funny that your argument here is akin to the anthropic principle. It's like you're trying to sound philosophically interesting but failing. Try harder, apply your concepts here to human life.
