Weikart is a Discovery Institute fellow and ID proponent. His book was underwritten by the Discovery Institute, and it has been deployed by creationists and IDers as a supposedly independent, academic confirmation of their “Darwin Caused The Holocaust” thesis.
The book is shoddy scholarship at best, and frankly dishonest if one wishes to be a little less charitable.
You can read some of the criticism of it here:

Failed attempts to blame the Nazis on Darwin aside, ID is not only not science, but anti-science as Ben Stein admitted himself (see post 377).
I am a little tired of the argument that proponents of ID make that it's not creationism in disguise. Even a freshman in high school can see through that charade. Who was the "Intelligent Designer"? ID doesn't have to tell you because you can't reach any other conclusion but that it was God. It wasn't Bill Gates.
In any event, it cannot be repeated often enough, since it rarely sinks in with many folks here, that evolution does not address the origin of life, and a belief in God and evolution is not at all logically or doctrinally inconsistent. Even the Vatican agrees with that.
