Jean Lightner just posted a good article up on AiG's website covering Creationary beliefs about biological change. She notes that Creationists should expect both bad mutations because of sin and death that is in the world, and good mutations because of the care that God put into His creation. She also made an interesting case for directed mutation in human pigmentation.
Basically, the argument goes like this:
This is a really cool direction of research. I also wonder what sort of mechanism would be used to control this. Is there a feedback loop somewhere which tells the skin that the pigmentation is set at the right level? Are the mutations prevented by methylation or some other epigenetic mechanism? Is there something there functioning as a counter to determine how many generations it should search for an optimum versus attempt to establish a constant sequence?
Anyway, another nice thing about this article is it cited my CRSQ paper. Yay! Now I just have to find time to finish my BSG paper :)
