Trees resulting from analysis of corrected matrix of Gingerich et al. (2011). MaiolinoStephanie M. BoyerDoug I. BlochJonathan C. GilbertChristopher GroenkeJoseph 2012 <p>A, Single most parsimonious tree including extant taxa and <i>Darwinius</i> only. This tree topology was produced from an exhaustive search using the corrected version of the Gingerich et al. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0029135#pone.0029135-Gingerich1" target="_blank">[8]</a> matrix (corrections noted in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0029135#pone-0029135-t009" target="_blank">Table 9</a>;see also <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0029135#pone.0029135.s010" target="_blank">Appendix S1</a>, section 10 for nexus file). This topology was also produced by analysis of the corrected matrix with additional characters noted in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0029135#pone-0029135-t010" target="_blank">Table 10</a> (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0029135#pone.0029135.s010" target="_blank">Appendix S1</a>, section 17 for nexus file). These trees differ only in statistics such as length, CI, HI, RI, and RC. See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0029135#s2" target="_blank">Results</a>.
