Aside from the general problem of trusting theoretical models strongly contradicted by the evidence, you should realise that "Mendel's Accountany" was created by the creationist J C Sanford to support his own arguments.
quote:
I can only guess that Mendel's Accountant is saying that since we're not extinct that researchers must have mismeasured the mutation rates. My own guess is that the Mendel's Accountant program has flaws.
It's meant to say that species can only last a few thousand years before going extinct, therefore YEC.
