Your thinking on this matter is incredibly messy and not guided by rigorous investigation of the facts. > Why would it stick around if it is not needed? WHY WOULDN'T IT??? It's not expensive to carry junk DNA around - it just sits there, not doing anything, not creating proteins, not affecting anything. You're proposing that there's some sort of janitor going through and cleaning up the nonsense and it's just not true. If there is such a mechanism, point to it. Name it. Tell me what it is. Tell me what the evidence of it is. Just link to a wiki page! I think the problem is that you're stuck on thinking about DNA as procedural program code instead of on its own terms, how it actually operates. I'll try to explain a few things, in a last ditch attempt to appeal to your intellect: DNA gets transcribed to mRNA based on START and STOP codons (codons being sequences of three bases). Then the codons in-between START and STOP on the mRNA strand get translated into amino acid chains, also known as proteins. The "ignore protocol", such as it is, is then twofold: 1) if a sequence doesn't occur between START and STOP, it's highly unlikely to ever get transcribed into mRNA, and 2) if an mRNA contains nonsense codons, or its number of base pairs is not divisible by three, then the resulting protein is most likely benign, or at least not harmful enough to prevent the organism from producing offspring and therefore propagating the harmful sequence. (If it is harmful enough to affect reproductive viability, then it doesn't tend to stick around very long.) Not all DNA does anything. Plenty of it is just hanging on for the ride, not harming anyone, and so not selected against by natural selection. > I call it peace at a certain point. I call it giving up the search. Just because you don't understand something doesn't mean you give up trying to understand.
