Valerie J. Grant is Lecturer in Behavioural Science at the School of Medicine, University of Auckland, New Zealand.
Grant has produced a well thought and coherent hypothesis on the effects that maternal personality could have on the human sex ratios. The literary format of the text provides what can be complex data in an interesting and informative manner that will engage with both an academic and general audience. The core concepts of the maternal dominance hypothesis are well explored throughout the book and are supported by valid research findings... Grant's considerations of the ethics and implications of attempts to alter human sex ratio by artificial means also make very engaging and thought-provoking reading. In conclusion I believe the text would be of interest to a variety of audiences, from evolutionary psychologists to reproductive physiologists, because of the breadth of empirical work studied and the consideration given to the implications of the theory and peripheral issues involving the human sex ratio. In short a well written book and highly recommended. - Mark Sergeant, The Nottingham Trent University, in 'Human Nature Review'
