This is hard to read. Seriously, both the author of the review and of the book (assuming the reviewer accurately portrays it) seem confused about evolution and have an incomplete or total lack of comprehension of ideas; like fitness landscapes, that evolution is not the result of a design process, and that traits can persist despite being neither adaptive nor maladaptive. Regarding the latter, there's a concept in cancer genomics – passenger mutations – which provides a DNA level example of this on a much faster timescale.
