|Examples of Protein Shapes|
Cornelius Hunter offers an interesting discussion on the problem at Darwin's God. He writes:
But [the protein] works just fine only because a very special amino acid sequence was specified. That amino acid sequence is just as astronomically rare as the three dimensional structure that the unfolded protein was able to find. So from where did this amino acid sequence come?DNA is a code. It's information. At bottom is the question of where information comes from. Can it be produced by chance and blind forces, or does it require intention and intelligence? We have never experienced information such as a code being produced apart from a mind, and yet despite the complete lack of empirical warrant the naturalist takes an enormous leap of faith and chooses to believe, without any evidence, that not only are such wonders possible but that they actually happened in the origin of living things.
The string of amino acids that make up a protein comes from the cell’s translating machine called the ribosome. The ribosome takes as input a string of nucleotides and produces as output a string of amino acids. The translation is done according to the genetic code.
And from where did the string of nucleotides come? It came from the DNA. A massive protein copying machine slides along an opened section of DNA and copies a gene.
And from where did the DNA gene come? According to evolution it evolved, but it is here that we find another entropy barrier. Just as the folding protein is confronted with an astronomical number of structures, so too the DNA gene is confronted with its own nightmare of choices. But that is where the similarities end.
Then the naturalist, having committed himself to the belief that unthinking nature is capable of such miracles, the equivalent of believing that a computer program could be produced by a random symbol generator, criticizes those who are skeptical as being superstitious and unscientific for thinking that the existence of information is evidence of the existence of an intelligent mind. Pretty funny, I think.
