Description

Our understanding of vertebrate origins and the backbone of human history evolves with each new fossil find and DNA map. Many species have now had their genomes sequenced, and molecular techniques allow genetic inspection of even nonmodel organisms. But as longtime Nature editor Henry Gee argues in Across the Bridge, despite these giant strides and our deepening understanding of how vertebrates fit into the tree of life, the morphological chasm between vertebrates and invertebrates remains vast and enigmatic. As Gee shows, even as scientific advances have falsified a variety of theories linking these groups, the extant relatives of vertebrates are too few for effective genetic analysis. Moreover, the more we learn about the species that do remain--from seasquirts to starfish--the clearer it becomes that they are too far evolved along their own courses to be of much use in reconstructing what the latest invertebrate ancestors of vertebrates looked like. Fossils present yet further problems of interpretation. Tracing both the fast-changing science that has helped illuminate the intricacies of vertebrate evolution as well as the limits of that science, Across the Bridge helps us to see how far the field has come in crossing the invertebrate-to-vertebrate divide--and how far we still have to go.

Media Reviews

"An excellent addition, complementing Gee's earlier book Before the Backbone, which provided a historical perspective on ideas surrounding vertebrate origins. Gee addresses an important topic for biologists and zoologists about vertebrates' place in the 'grand scheme.' We are familiar with vertebrates, or think that we are. However, Gee shows beautifully, as a group we are just as strange in many ways as other groups appear to us. Across the Bridge takes on a very esoteric subject and is genuinely witty and charming. The book really is magnificent."--Neil J.
