I went back and rechecked the link. It's by a creationist at UNC who specifically says that his material does not represent UNC. Sorry.

Here's a couple of other links that call it into question since you probably wouldn't trust a self-declared Creationist:

link 1 (This guy assumes evolution to be true)

link 2 (An intelligent design proponent.)

Sometimes there are problems calibrating the clocks. I saw mtDNA attacked as particularly unreliable last year.

This does not help you that much. There's noise in everything in real life. There's also signal and it's real and convincing if you have a brain and it's not turned off.

The line of evidence that comes from these clocks tends to confirm the results from elsewhere. To the extent you want to say some reliability problems are fatal, tell AndrewC.

He thinks molecular evidence trumps all other lines of evidence, always. Maybe not always. When he needs it.
