In Darwin’s Dilemma there are mysterious sudden appearance of dozens of major complex animal types in the fossil record without any trace of the gradual transitional steps Charles Darwin had predicted in his theory.

It also makes other arguments for the supposed impossibility of getting new genetic information by Darwinian natural selection process.
