The Origin of Vertebrates
Walter Holbrook Gaskell
Where did the backbone come from? Walter Gaskell traces the origin of vertebrates, arguing a bold theory of how animals with spines arose from earlier forms. Detailed, ingenious, and controversial. A deep dive into one of the great puzzles of comparative anatomy. For readers drawn to the deep origins of the animals we know best, ourselves included. Trace the backbone back to its beginning.
