ping for reference. BTW, I have seen DNA decay as an argument FOR YEC. Some Japanese fellow claiming thermal decay predicts no DNA could survive more than about 10K years, even under the most perfectly protected conditions. Creation magazine (Answers in Genesis) touted this as a basis for being suspicious of dating any discovered dinosaur DNA to periods significantly beyond the 10K limit. And this new proposal on half-life does not seem to be inconsistent with that premise. Perhaps I am missing the point, but I do not see how this harms the essentials of the YEC position at all.
Answers in Genesis? Ken Hamm is a buffoon who can’t be taken seriously in the creation-evolution debate.
