Description:
Jarvis et al. (Research Articles, 12 December 2014, p. 1320) presented molecular clock analyses that suggested that most modern bird orders diverged just after the mass extinction event at the Cretaceous-Paleogene boundary (about 66 million years ago). We demonstrate that this conclusion results from the use of a single inappropriate maximum bound, which effectively precludes the Cretaceous diversification overwhelmingly supported by previous molecular studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mitchell, Kieren J -- Cooper, Alan -- Phillips, Matthew J -- New York, N.Y. -- Science. 2015 Sep 25;349(6255):1460. doi: 10.1126/science.aab1062.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Australian Centre for Ancient DNA, School of Biological Sciences, University of Adelaide, Australia. kieren.mitchell@adelaide.edu.au. ; Australian Centre for Ancient DNA, School of Biological Sciences, University of Adelaide, Australia. ; School of Earth, Environmental, and Biological Sciences, Queensland University of Technology, Brisbane, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26404819" target="_blank"〉PubMed〈/a〉
