ORIGINAL: Daddy4UdderSlut Mastermind, As the hour gets later, my posts may wander increasingly ;-) ...but I wanted to add something and hopefully say it in less than a gazillion words this time... Not only is the close similarity of homologous proteins in so many disparate organisms evidence for a common ancestor, but the mere fact that virtually *all* of them, millions of species use precisely the same mechanism, DNA, as the method of encoding the instruction set for life, is also powerful evidence for a common ancestor. While there may be more, the only exceptions to the DNA coding that I know of are retroviruses, and the newly discovered prion "organisms" (like the bugs making Mad Cow Disease). Think about it, you and a fungus use the same alphabet to write the instructions for life. How cool is that??? I don't mean that in a flippant way, either, I find it absolutely fascinating, and somehow spiritually satisfying, this connection between all organisms. We can insert a gene from a human being into a bacterial organism, and it will then produce not only that human gene in its offspring, but it will produce the corresponding protein, so there is nothing special or fundamentally different about human genes versus bacterial genes. (If you want to get technical, there are some subtle distinctions at a fine grain, though, but that's for a different discussion). We do that exact process in fact, to manufacture protein therapeutics, like insulin. Human genes, inserted into bacteria, produce human hormones, which we harvest and put back into humans... mere coincidence that this is possible??? And even the retroviruses (via Reverse Transcriptases) and prions (via specific proteins) are encoded in a manner very much a part of the DNA-RNA-protein system of life common to all discovered life. It is extremely cool, and to me more spiritual than any religious mythology has ever been. Maybe the soul is made of proteins. For those typing hate mail, please understand, of course, that I mean Jesus Intelligently Designed it that way. I'm pretty sure somewhere in Paul's letters it details how the Apostles turned wine into Telomerase Reverse Transcriptase. Complete with funny stick diagrams.
