Evolution in Action, a resounding success on its initial publication in 2007, is a unique and beautiful attempt to provide a map of those billion years in time. In this sublime mosaic of photographs and text, evolutionary biologist Jean-Baptiste de Panafieu and photographer Patrick Gries explore the skeletal record, showing through words and images the defining mechanics of all living vertebrates, including human beings.

Here is a powerful pairing: two hundred stark black-and-white photographs produced by Patrick Gries in collaboration with the Museum of Natural History in Paris are accompanied by text from scientist and documentarian Jean-Baptiste de Panafieu. The result is a revealing collection that profoundly illustrates the key themes of evolution homology, convergence, adaptation, polymorphism and more.

Now updated and presented in a smaller format with fifteen new gorgeous photographs, Evolution in Action steps beyond the debate and presents the undeniable truth of Darwins theory, showing through skeletons both obscure and commonplace, but always intriguing, the process by which life has transformed itself, again and again.
