Despite being a defining feature of the vertebrates, much remains to be understood about vertebral development and evolution. Particular controversy surrounds whether vertebral component structures are homologous across vertebrates, how somite and vertebral patterning are connected, and the developmental origin of vertebral bone-mineralizing cells. Here, we assemble evidence from ichthyologists, palaeontologists and developmental biologists to consider these issues. Vertebral arch elements were present in early stem vertebrates, whereas centra arose later. We argue that centra are homologous among jawed vertebrates, and review evidence in teleosts that the notochord plays an instructive role in segmental patterning, alongside the somites, and contributes to mineralization. By clarifying the evolutionary relationship between centra and arches, and their varying modes of skeletal mineralization, we can better appreciate the detailed mechanisms that regulate and diversify vertebral patterning.<\/jats:p>","DOI":"10.1242\/dev.118950","type":"journal-article","created":{"date-parts":[[2015,5,12]],"date-time":"2015-05-12T11:20:20Z","timestamp":1431429620000},"page":"1733-1744","source":"Crossref","is-referenced-by-count":129,"title":["Building the backbone: the development and evolution of vertebral patterning"],"prefix":"10.1242","volume":"142","author":[{"given":"Angeleen","family":"Fleming","sequence":"first","affiliation":[{"name":"Department of Physiology, Development and Neuroscience, University of Cambridge, Downing Street, Cambridge CB2 3EG, UK"},{"name":"Department of Medical Genetics, Cambridge Institute for Medical Research, Wellcome Trust\/MRC Building, Hills Road, Cambridge CB2 0XY, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcia G.","family":"Kishida","sequence":"additional","affiliation":[{"name":"Department of Physiology, Development and Neuroscience, University of Cambridge, Downing Street, Cambridge CB2 3EG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles B.","family":"Kimmel","sequence":"additional","affiliation":[{"name":"Institute of Neuroscience, 1254 University of Oregon, Eugene OR 97403-1254, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roger J.","family":"Keynes","sequence":"additional","affiliation":[{"name":"Department of Physiology, Development and Neuroscience, University of Cambridge, Downing Street, Cambridge CB2 3EG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042608035401100_DEV118950C1","doi-asserted-by":"publisher","first-page":"71","DOI":"10.1016\/S0925-4773(00)00481-0","article-title":"The developmental fate of the rostral\/caudal half of a somite for vertebra and rib formation: experimental confirmation of the resegmentation theory using chick-quail chimeras","volume":"99","author":"Aoyama","year":"2000","journal-title":"Mech.
