I've got a creationist that keeps telling me about all of the 'homologous frogs with vastly different DNA', whatever that means.  I have asked him just what he was talking about and where he heard about it and he answered 'Uncommon Dissent' the Dembski book.

I'm sure not going to go out and get this book, was wondering if you guys had any info about it.

For the record, he was also talking about other 'homologous organisms' with vastly different DNA and I questioned him, which ones?  he said marsupial and placentals...  of course if you define 'homologous' loosely enough that could mean anything.  or in this case, nothing.

Re 'homologous frogs with vastly different DNA'

I thought the word "homologous" referred to features or traits. Applying it to whole organisms doesn't make sense to me.

With frogs having different DNA, the question would be is that consistent with the length of time since those frog species separated from their last common ancestor. That would (I think) be shortly after the first appearance of amphibians (i.e., it would probably precede the first appearance if anything close to reptilian, let along mammalian or avian).

On marsupial vs. placentals, I recall some discussion of that fairly recently, I think either in one of the threads on the AtBC forum or on the Panda's Thumb blog; the time of that split might still be an actual controversy.
