Helix, the example I gave you of whales becoming whales left out most of the problems. I was just dealing with the mathematics if absolutely everything possible had happened the way evolutionists want it to.
But there's more. The cell operates via proteins in large part. Each protein has a function and a place. The cell knows what to do with it. Stick a strange protein in there and the cell will dismantle it and use the pieces (amino acids) for making a protein it can use. In fact a good many proteins in most cells are disassembled regularly and the parts used for fresh, new proteins.
Hold that thought.
There is no way known by any microbiologist in the world for a cell to construct a 'de novo' protein -- a protein never before made by that cell.
Those proteins are required for evolution to happen.
Suppose, by some weird jerk in the DNA, the IMPOSSIBLE did happen, and the cell constructed a brand new (to it) protein. The cell body would not know what to do with it and would deconstruct it!
Here's another problem with that mathematical scenario which I did not include: mutations can back mutate as easily as forward mutate! In other words, with the first, or second, or third, or whichever beneficial mutation, there is no reason in the world for it not to reverse itself and back mutate to the wild or original form.
Another glitch: sexual reproduction. Most mutations are either 'buried' or eliminated entirely from a population through the mixing of genes in sexual reproduction. The hopefully beneficial mutation must not only contribute to the animal's well-being (or be silent), it must be dominant. It must be there generation after generation in the population.
You see, it is not just the loss of legs for your evolved whale, it is the GAINING of other things needed for what whales have and do now. As I asked, how did the air intake migrate to the top of the head? How did the blood chemistry change? How did the flukes form? And so many other changes! All of these take a series of changes that is impossible biologically/genetically.
The ONLY thing connecting the whale with supposed ancient land ancestors is imagination. There is absolutely no evidence for it. It is a move of desperation in order to avoid God and His Word, actually. You've shown that yourself by ignoring so much of what I wrote in the previous post.
