To make it even worse, the book goes on to point out that there are (unarguable, in my opinion) similarities between construction of a whale fin and a human hand. Based on this, they conclude that there is no God.

I'll bet you can't produce a quote from any textbook that makes this argument.

"Descent with modification is evident in anatomical similarities between species grouped in the same taxonomic category. For example, many of the same skeletal elements make up the forelimbs of humans, cats, whales, bats, and all other mammals, although these appendages have very different functions (figure 22.9). Surely, the best way to build a bat's wing is not also the best way to build whale's flipper. Such anatomical peculiarities make no sense if the structures are uniquely engineered and unrelated."

Talk about ego. These guys feel they know best how to engineer living beings. Since God failed to do it to their specs, he cannot possibly exist. QED.
