"Interesting. Where has this happened? Examples?" - JS1138
I'll take up that burden if you'll first be willing to post, in black and white, that you agree with the stated concept. Specifically, that genetic code skipping conclusively and irrefutably disproves Evolutionary Theory.
I am not a biologist and do not know all the technicalities, but I agree in principle that DNA evidence could disprove common descent. This principle has been stated numerous time on these threads, always by evolutionists.
But there's a problem with the specific way you've stated your case. Darwin published 145 years ago, knew absolutely nothing about genetics -- a concept not yet invented, and classified descent by morphology. So the answer to your your question, in the exact words you have used, is no.
I know there is a mechanism called "back mutations" which can restore lost information such as your hypothetical gene 451. What I don't know is the rate at which such mutations occur. Any idea?
