Mr. Taylor is a judicious intermediary between science and the layman (books-The Science of Life, etc. and BBC commentator), neither overly sanguine nor speculative, and fully alert to the ethical as well as personal and practical problems which extend from in vitro to in vivo situations. Biology, to a degree outstripped by physics and chemistry, is now accelerating in many sensitive areas: considered here are the most immediate (five to ten year) changes in the foreseeable future. Some of them are already familiar realities--others less so. Among them: contraception, and controlled reproduction of say an elite; modified man (via transplants); the repudiation of aging and the reprieve of death; the control of intelligence, mood and memory; the determination of sex in the unborn as well as the creation of life. . . . While perhaps the appeal here will be chiefly to the interested reader (although all these areas concern everyone), the book will be equally accessible to those without any particular knowledge in this discipline and it is sound popular science.
