I would like to make two points, one concerning his last comment, and one
about statistical studies based on constant mutation rates.
1. Glenn concludes:

Whose house is out of order? Human biologists or Christians? These papers,
if they "scream" for anything, scream for a reassessment by human
evolutionists of many of their present cherished views. The apple cart
has been turned upside down, and much scrambling has occurred. This is not
to say that the basic picture of human evolution has been altered. But
much recent work based on mutational studies now seems suspect.
It is nice that there are a few Christian folks like Glenn who are
attempting to match Christian apologetics with new data, but most
Christians have more important things to do than, schizophrenicly, to
match Christian apologetics to the ebbs and flows of scientific research
-- particularly during times of significant transition.
2. This gets to my second point. Glenn quotes Hagelberg et al (1999):

Many statistical studies based on mutation rates have *assumed* a constant
mutation rate. A ratio of eight to one is not even close to constant. This
suggests (to me at least) that any study which must depend on an assumed
uniform mutation rate needs to viewed with considerable skepticism.
