Here, we present a robust molecular phylogeny based on the nuclear RAG1 gene as well as results from a variety of alternative independent molecular clock calibrations. Our analyses suggest that the origin and early divergence of the three living amphibian orders dates back to the Palaeozoic or early Mesozoic, before the breakup of Pangaea, and soon after the divergence from lobe-finned fishes. The resulting new biogeographic scenario, age stimate, and the inferred rapid divergence of the three lissamphibian orders may account for the lack of fossils that represent plausible ancestors or immediate sister taxa of all three orders and the heretofore paradoxical distribution of some amphibian fossil taxa. Furthermore, the ancient and rapid radiation of the three lissamphibian orders likely explains why branch lengths connecting their early nodes are particularly short, thus rendering phylogenetic inference of implicated relationships especially difficult.</dcterms:abstract> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/7543"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:35:17Z</dc:date> <dc:language>eng</dc:language> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:contributor>Meyer, Axel</dc:contributor> <dc:contributor>Zardoya, Rafael</dc:contributor> <dc:contributor>Vences, Miguel</dc:contributor> <dcterms:bibliographicCitation>First publ. in: The American Naturalist, Vol. 165 (2005), No. 5, pp. 590-599</dcterms:bibliographicCitation> <dcterms:issued>2005</dcterms:issued> <dc:contributor>San Mauro, Diego</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:35:17Z</dcterms:available> <dc:rights>deposit-license</dc:rights> <dc:creator>Vences, Miguel</dc:creator> <dc:format>application/pdf</dc:format> </rdf:Description> </rdf:RDF>
