This, then, is not only a book that grapples with some of the most profound issues in biology but also a professional autobiography; a life history that has intertwined with the life cycles under study....Bonner's book ought to be a classic. --Peter Calow, The Times Higher Education Supplement Bonner's prose is a felicitous blend of science simply explained, gentle but insistent rigor, and a fetching triad of wry humor, personal anecdote and unexpected diversion.

We will never be able to look at a rotting log in quite the same way again or dig through the soil in the garden. --Steven Austad, Natural History
