Many species have now had their genomes sequenced, and molecular techniques allow genetic inspection of even non-model organisms. But as longtime \u003ci\u003eNature\u003c\/i\u003e editor Henry Gee argues in \u003ci\u003eAcross the Bridge\u003c\/i\u003e, 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. \u003cp\u003e\u003c\/p\u003e 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, \u003ci\u003eAcross the Bridge\u003c\/i\u003e 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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Henry Gee\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 022640305X\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9780226403052\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e University of Chicago Press\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/02\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 288\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.90lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.90h x 6.00w x 0.80d\u003cbr\u003e\u003cbr\u003e\u003cb\u003eReview Citation(s): \u003c\/b\u003e\u003cbr\u003e\u003ci\u003eChoice\u003c\/i\u003e 02\/01\/2019","brand":"Henry Gee","offers":[{"title":"Paperback","offer_id":48457660039423,"sku":"9780226403052","price":29.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_8d0aa0d0-db6d-485b-87f0-90b5c09a43bf.jpg?v=1777400351","url":"https:\/\/www.whiterainbookhouse.com\/products\/across-the-bridge-henry-gee-9780226403052","provider":"WR Book House","version":"1.0","type":"link"}
