Joint review with The Cambridge Companion to Darwin, 2nd edition: ' … undeniably a great introduction to Darwin, his ideas and his legacies. With the wealth of historical and philosophical analyses, and the great variety of contributions covering major problems within the field, they constitute an indispensable tool for any teacher or student of Darwin and Darwinism. The general public will find a complete presentation of Darwin's thinking, while the scholarly can enjoy a number of revisionist claims sure to provoke responses, critical and otherwise.'
