What comes first, form or function? Evolutionary developmental biology (or "evo-devo") answers this fundamental question by showing how evolution controls the development of organisms. Alessandro Minelli takes an in-depth and comprehensive look at the history and key issues of evo-devo, focusing on the innovative ways animal organisms evolve through competition and cooperation. Minelli provides a complete overview of conceptual developments--from the fierce nineteenth-century debates between the French biologists Geoffroy and Cuvier, who fought over questions of form versus function--to modern theories of how genes dictate body formation. The book's wide-ranging topics include expression patterns of genes, developmental bias, the role of developmental genes, and genetic determinism. Drawin
