More than a month ago now Jeffrey Tomkins published a DpSU on the ICR’s website called Study Shows Proteins Cannot Evolve. He also posted it on his own blog, Designed DNA, a couple of days later as he often does. Because it appeared the last day before exams I didn’t have much time to write anything more than a recommendation that you compare Tomkins’ article with a blogpost by fellow young Earth creationist Todd Wood on the same subject.
However, it appears that somebody else got in contact with Tomkins about it as on November 22 he published another post on his blog (have I mentioned that I still have a couple of posts from last month to do? I still have a couple of posts from last month to do), called Are Bigger Proteins More Favorable to Evolution? He opened:
I recently wrote an article discussing a recent research paper that showed how proteins contain non-negotiable sectors that are intolerant of amino acid changes and that when the other protein sectors that may tolerate such changes are altered, the changes often reduce quality of protein function. The 3-dimensional structure that proteins fold into, is also affected by the sequence of amino acids.
