I’m sorry that maybe I didn’t understand what you were asking. His book is next on my list after Genetic Entropy. But I don’t think he dismisses time-dependent rate of mutation but instead checks against both evolutionary and creationist rates in his papers. Maybe I didn’t explain something correctly before. I’m still hazy on how these things are measured. I’m better at understanding the conceptual arguments.
Figures 1 and 2 I’m assuming are testing time-dependent rate. I think I said “de novo” before, but maybe that’s not a right explanation. Evidence Human Y Chromosome Molecular Clock | Answers Research Journal
