I've studied biochemistry, evolution, and oncology, but it is just marvelous to have a professor of biochemical evolution who is widely knowledgeable in his field and in the history of its development discuss the relationship of all of these (as well as the origin of life, the possible causes of aging, and the missing hereditability from GWAS studies) with precision and clarity. Additionally, the cost of the book is probably justified by the author's annotated recommendations for further reading by themselves.
