“Addresses an important topic for biologists and zoologists about vertebrates’ place in the ‘grand scheme’ . . . genuinely witty and charming . . . magnificent.” —Neil J. Gostling, University of Southampton 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 non-model 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 sea-squirts 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. “A beautiful ode to some of the least appreciated animals . . . guides the reader joyfully through deuterostomes—weaving disparate elements of embryology, paleontology, and morphology into an unprecedented and accessible narrative.” —Jakob Vinther, University of Bristol

We cannot catechise our stony ichthyolites, as did the necromantic lady of the Arabian Nights did the coloured fishes of the lake which had once been a city, when she touched their dead bodies with her wand, and they straightaway raised their heads and rephed to her queries. We would have many a question to ask them if we could - questions never to be solved. Hugh Miller, The Old Red Sandstone When I started this book in 1991, the subject of vertebrate origins was fusty and unfashionable. Early drafts for this preface read like an extend ed complaint at the lot of traditional morphologists, cast aside by the march of modern molecular biology. But no longer - this book should reach you at a time of renewed inter est in the origin of the vertebrates, our own particular corner of creation. For although the topic has excited interest for well over a century, molec ular biology has only lately achieved the maturity necessary to test its predictions. As a legitimate field of study, it is fashionable again.

Excerpt from The Ancestry of Vertebrates: As a Means of Understanding the Principal Features of Their Structure and Development Those who have read the book to the end will admit that this theory, to say the least of it, merits earnest consideration. They will admit that, unlike most other similar theories, it not only serves to explain known facts but that also its application has advanced us further in several respects. Of these I will mention here only the problem of the hypoglossus and its relation to the gill-slits and the cranium (cf. Plate and the results given in the last chapter. In the treating of the different problems, I have tried each time to give the reader first an idea of the divergent opinions and the confusion often prevailing. Though this does not make the reading of the book easier and more agreeable - problems having been made often much more complicated by the investigators than they are in reality I have thought it advisable to do so in order to emphasize the value of a means of escaping from this confusion. The expressing of a persons thoughts correctly in a foreign language is no easy matter. I 'am greatly indebted, therefore, to Mr. Humphreys, officer of the Royal Flying Corps who was interned in The Hague during the year 1918. For having gone over with me the whole article, and to Mr. Moon, engineer of Batavia, for having once more reread with me the proofs If in spite of this the English be not yet perfect, I trust that these imperfections, if any, will not give rise to any misunderstandings.
