The longer post doesn't add very much to the argument but it does have something interesting at the bottom. Here's what Rob Sheldon says about the Onion Test and junk DNA.
I don't even know why the Onion Test keeps getting mentioned anymore unless it is a red herring to impress the masses, like Carl Zimmer. The idea assumes that DNA does one job and one job only -- making protein -- with one protein per gene. So if the DNA lacks the start/stop codons needed for making protein, it obviously isn't doing its job. This was "Central Dogma" gospel thirty years ago or so.To say that the Onion Test has something to do with assuming that the only job of DNA is to make protein is either incredibly stupid or a blatant lie. Probably both. To claim that this has something to do with the Central Dogma of Molecular Biology is also a lie.
But once the DNA was found to have moonlighting jobs doing other things -- development, differentiation, regulation, mechanical attachments, iRNA anti-virals, information compression -- then the Onion Test simply makes no sense any more.
Here's what I don't understand about Intelligent Design Creationists. There are some who know full well that what Rob Sheldon says is untrue but they don't challenge him and correct the misinformation that he is spewing on the creationist websites. (I'm not talking about "journalist" Denyse O'Leary.)
You'd think that they would do this in order to maintain some level of credibility but that doesn't seem to matter. I'm reminded of Bill O'Reilly who has lied about many things in the past but this seems to be irrelevant to FOX TV. I suppose I ought to give up trying to educate the IDiots and just assume that Uncommon Decent and Evolution News & Views (sic) are not really interested in the truth.
