Description
Book SynopsisOriginally published in 1933, this book is a culmination of a lifetime of research by Hans Friedrich Gadow into the evolution of the vertebrae. Gadow outlines the various forms of vertebral development as a guide to larger and more general questions on the morphological scheme of the evolution of vertebrate creatures.
