Oh they understand perfectly - but by using those false analogies it allows them to keep their false beliefs. All they are able to do is work within the framework of already existing genomes. Yet they want us to believe we started with C and ended up with CATG, when all biologists understand the impossibility of this, even evolutionary biologists.
The formation of the original biomolecules is
not the purview of evolution. Certainly in the organisms we're dealing with
have CATG, and have had it. This distraction of "where did the other nucleotide bases come from" is pointless. The formation of early DNA is a matter of abiogenesis. However, there is no denying that all creatures alive have DNA, and that this DNA can be subdivided into nucleotide base pairs, and that those nucleotide base pairs are made up of Adenine, Guanine, Thymine, and Cytosine. There's no denying that any early organism, at least past the multicellular stage, must have had DNA.
However, let's go a step further and entertain your hypothesis. DNA is necessarily made up of base pairs; it is impossible to have "just C". So we necessarily need either CG or AT. And even with just CG or AT, guess what: we still have everything we need for an increase in genetic information, because now instead of a quarternary alphabet, we have a
binary alphabet, and we already have established very firmly that yes, a binary alphabet can produce new information.
But what if we had just C? (For example, if all we have is RNA, rather than DNA.) Well, then what we have is a non-random system. RNA with just Cytosine no longer has any variables; you can always predict exactly what the next letter in the sequence will be, and therefore it carries
no information.
So yeah, your argument makes absolutely no sense on several different levels, is completely irrelevant, and somehow is
even more wrong than the typical "you can't add new information" arguments.
They continuously ignore their own biologists in plant and animal husbandry - the only place mutation experiments were performed regarding reproduction - the rest is just in their minds.
Once again, I feel the need to point out that Lönnig's view is not some consensus within plant and animal husbandry. His paper was published in an obscure, open-access journal and cited by... um... him. Four times. That's it. Given that this paper supposedly disproves the cornerstone of all of biology, that should raise a few eyebrows.
Meanwhile, mutation experiments are thick on the ground in molecular biology, virology, evo-devo, and numerous other fields. I'm not sure why you'd think that plant and animal husbandry are the only places where such experiments took place, or why those experiments would be considered particularly meaningful, given that the goal was never to show any particular divergence.
Funnily enough, Lönnig thinks your arguments about genetic information are bogus as well:
The status of mutation breeding today is that of “an occasionally used supplement to traditional methods”, just “occasionally useful in enlarging the genetic base of a programme in a limited and highly specific fashion”.
Oops.
In any case, I don't know enough about mutation breeding to comment, but I'm getting the impression that it generally only produces point mutations. If that's the case, then Lönnig's "law" is kind of a no-brainer; you can only accomplish so much with point mutations. Mutation breeding is
not a proxy for evolution and was never performed with the goal of simulating evolution or creating new species.
What a phenomenal non-answer. Just looking through that list from "Adherents", in the first five, I can see nobody who rejects the theory of evolution and one person there who is
definitely not a Christian!
Nor did they find any evidence to suggest it didn't occur that way - except they chose to believe it didn't.
Should I email him again? Because I totally can. However, I get the feeling that if they found no evidence to indicate that HGT was present, and you
should find evidence if HGT is present, then there's good reason to believe it wasn't HGT.
