OP I believe this is the "nail in the coffin" you seek.
above top secret.........
Not.
The linked article is very well written and starts off all warm and fuzzy, lulling the incautious reader into thinking that the author is respecting
the science, unlike the religious fundamentalists that are usually writing these things. The author seems to be mindful of the science behind DNA, and
is trying to talk to those who are offended by the fundamentalists rejection of science.
Then he comes unstuck in an extremely spectacular fashion, but hides it in a throwaway assertion:
In addition, this type of high-level information has been found to originate only from an intelligent source.
That is wrong and is the basis of the entire rest of the article. He goes on to describe some interesting statistical factoids, then reveals his
actual distrust and misunderstanding of DNA:
If a mistake occurs in one of the most significant parts of the code, which is in the genes, it can cause a disease such as sickle-cell
anemia.
Two things he isn't telling you about this:
(1) DNA replication 'mistakes' don't all cause disease. Some do, some don't, most are neutral, some are harmful in other ways, some are
advantageous. This is the engine room of evolution, and if you are going to accept the science of DNA, like the author has pretended to do for the
previous thousand words or so, then you have to accept and understand that simple fact.
(2) The particular mutation he is referring to actually PREVENTS disease, and it has maintained its place in the human gene pool precisely because of
that. If all it did was cause sickle-cell anemia, it would have dropped out of the gene pool thousands of years ago, because sickle-cell sufferers die
in childhood (without modern treatment), before they have born children to carry it on.
If you inherit the 'sickle cell' gene from ONE of your parents, you have a distinct advantage over other people if you live in malaria prone area
like equatorial Africa or South America or Southeast Asia, because it protects against malaria. That means if you are more likely to survive childhood
and reproduce than your friends who don't have the gene. It is only if you inherit the gene from BOTH your parents that you may get sickle-cell.
Humans have had elaborate taboos about marrying folks too closely related for just this kind of thing. You don't have to be a modern scientist to
notice that your kids tend die young if you marry too close.
The author continues to reveal his true loathing for the actuality of DNA science with this gem:
So to believe that the genetic code gradually evolved in Darwinian style would break all the known rules of how matter, energy and the laws of
nature work.
In fact the exact opposite is true. To believe that the genetic code gradually evolved in Darwinian style
is to understand exactly how the
known rules of how matter, energy and the laws of nature work.
He then goes completely off the rails:
It is good to remember that, in spite of all the efforts of all the scientific laboratories around the world working over many decades, they have
not been able to produce so much as a single human hair. How much more difficult is it to produce an entire body consisting of some 100 trillion
cells!
And that is relevant exactly how? Scientists aren't studying evolution in order to build a human hair. Pharmaceutical companies might like to market
something like that, I suppose, but why would you suppose that a scientist would show how a human hair would take a million years (or whatever) to
evolve and then try to duplicate that over night (relatively speaking).
Building an actual human hair in a lab from scratch would probably disprove evolution anyway, so how you can anyone think that the lack of building
one is an argument against evolution?
The only nail on the coffin I see here is the one with 'Credibility of Intelligent Design' written on it.
