Description:
Cohorts of marine taxa that originated during recoveries from mass extinctions were commonly more widespread spatially than those originating at other times. Coupled with the recognition of a correlation between the geographic ranges and temporal longevities of marine taxa, this observation predicts that recovery taxa were unusually long-lived geologically. We analyzed this possibility by assessing the longevities of marine genus cohorts that originated in successive substages throughout the Phanerozoic. Results confirm that several mass extinction recovery cohorts were significantly longer lived than other cohorts, but this effect was limited to the post-Paleozoic, suggesting differences in the dynamics of Paleozoic versus post-Paleozoic diversification.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, Arnold I -- Foote, Michael -- New York, N.Y. -- Science. 2003 Nov 7;302(5647):1030-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geology, University of Cincinnati, Post Office Box 210013, Cincinnati, OH 45221-0013, USA. arnold.miller@uc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14605366" target="_blank"〉PubMed〈/a〉
