By replacing a gene, you are talking about an incredibly complex change in sequences of codons to produce the right amino acids, to produce the right proteins that produce the right cells that produce the right genes. (snip)
You are assuming this complexity is necessary for the argument. All I was pointing out is that a single-point mutation could change one's eye color, regardless of how the genes are expressed.
Thus, your claim "If you mutate a gene, you replace one that was
critical in the parent." is refuted. I emphasized the most important word, to clarify where you went wrong.
That too would have nothing to do with natural selection. Natural selection destroys possibilities.
Natural selection is not quite as simple as that.
Mutations, and genetic drift create the opportunity for new possibilities to occur.
Here is a brief article responding to some of your claims about mutations:

This article makes reference to experimental results. So far, nothing you have written has done so.
Also, you ignored the fact that you "replaced" the gene. You didn't add it.
Okay, in that example I gave, you are right. That does not mean new genes can never be added to the genome. Perhaps I can point to some examples where this has happened:
Some can be found in this article:
http://www.talkorigins.org/indexcc/CB/CB101_2.html
Which points to lots of experimental results!
If you have the time, you can read this other article, which is long, but explains a lot about how the number of chromosomes can change over time:

Natural selection kills off the "weaker" so thats why the weaker never become stronger in another context. You wipe out the possibility of the others. In one context, one life form has a benefit over the other. But in other contexts, the opposite is true. So there was no "absolute better, no absolute winner or loser". There is simply the chance one benefits in the first context but in the second context they are both dead. It just depends on the situation you are in. To say the weaker in context one has nothing to add and must move out of the way, if the tables turn, the stronger becomes the weaker and dies whereas the one opportunistically killed of, would have survived.
I think your wording is a little more difficult to comprehend than mine, but I think I catch your drift. You are claiming the currently-weaker get killed off, before they have the chance to show they can survive in future situations where the currently-stronger would become the ones to get killed off.
That is true, to a certain degree, but that is why it is important to understand where new genetic variation comes from. Do a little research on the subject, examine the experimental results, and see for yourself how it is possible.
You think in too much in absolutes.
First of all, I was restating your claim so others could understand what you meant. I was not trying to defend it.
And secondly, that "thinking in absolutes" could be one of your problems, not mine. Perhaps you are not familiar with my history, but I have been known to fight for provisional knowledge and science, and against absolutist ideologies, for quite a while.
Meanwhile, your insistence on God an absolute creator is blinding you to the power of the investigations science has made, and continues to make.
