The first 162 pages of this book are great. Steele could spin them off into a short textbook. The explanations of antibody diversity, gene rearrangement and hypermutation are really very good. The rest is a little hard to believe, and where the immune system is concerned doesn't even make sense. Adaptability and variability, not hard-coding, are key to the immune response, so it seems that what he proposes--that learned responses could be passed back into germ-line DNA--wouldn't even be benficial if it were to turn out to be true considering the rate at which most pathogens mutate. But, let the experts address that question. For an overview of antibody production, this is done well.
