'A beautifully and lucidly written book of great insights … I have not seen in one volume such clear analysis of the nuanced view of the 'gene' … A valuable book that gives genes a new and accurate meaning and does justice to understanding genetics in a non-reductive [manner] through a systems approach. The clarity, precision and insights are wonderful.' Sheldon Krimsky, Tufts University, Massachusetts
