Description:
On the basis of new information from the 10th specimen of Archaeopteryx, Mayr et al. (Reports, 2 December 2005, p. 1483) suggested that birds, or avian flight, originated twice. We investigate the statistical support for this phylogenetic hypothesis and show that it is no better supported by available morphological character data than the hypothesis of a single avian origin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corfe, Ian J -- Butler, Richard J -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1238; author reply 1238.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, University of Bristol, Wills Memorial Building, Queens Road, Bristol, BS8 1RJ, UK. ian.corfe@bristol.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16946054" target="_blank"〉PubMed〈/a〉
