'What I love about the field of Criminology is that insofar as theories are concerned, Criminology welcomes all comers with open arms, while insofar as empirical methodology is concerned, Criminology never strays from its singular devotion to a standard of excellence. This exciting new book edited by Beaver and Walsh is quintessentially Criminology. It marries innovative bio-social theory of crime with rigorous empirical science...and somehow manages to make it all very readable. Anyone who wishes to be a contemporary criminologist must make themselves familiar with the content of this new book. Any criminologist who does not read this book is by definition falling behind the times.' Terrie E. Moffitt, Duke University, USA and King's College London, UK 'This is the most impressive, comprehensive, and informative review of research on biological contributions to criminology. It should be required reading for all criminologists who are interested in understanding and explaining criminal behaviour.' David P. Farrington, University of Cambridge, UK
