"I warmly welcome this new edition. The author has expanded and updated the content and scope and I am delighted to see that he has maintained the critical approach so important in the first edition. The expansion of the old material and inclusion of newer material means that this text will form a good 'fit' to any of the numerous evolutionary courses now on offer, whether as undergraduate options, or for more advanced master's programs."
