ular results to rigorous morphology-based phylogenies can help prevent us from being misled in these cases. Areal-world example illustrates this idea. Sites et al. (1996) presented a phylogeny for iguanid lizards based on mtDNA sequences from the ND4 gene, which con-flicted with a tree based on morphology (de Queiroz, 1987).

Ophiuroid systematics is currently in a state of upheaval, with recent molecular estimates fundamentally clashing with traditional, morphology-based classifications. Here, we attempt a long overdue recast of a morphological phylogeny estimate of the Ophiuroidea taking into account latest insights on microstructural features of the arm skeleton.

Conclusion: Have We Exhausted Morphology-Based Studies of Phylogeny in Placentals? The long history of comparative anatomy has led some to believe that we have exhausted the potential of morphological characters in phylogenetic analysis ( Scotland et al., 2003 ), especially as it concerns placental mammals.

Phylogenetic analyses. The phylogeny resulting from Bayesian analysis (see Supplementary Fig. S2) was similar to the ML tree with the only differences occurring in some areas of the tree with low to moderate branch support in one or both analyses, e.g., relationships among some genera of Nirvanini and Evacanthini.

A researcher is trying to construct a molecular-based phylogeny of the entire animal kingdom. Assuming that none of the following genes is absolutely conserved, which of the following would be the best choice on which to base the phylogeny? A) genes involved in.

tions of this phylogeny are examined. A European origin for Pholidota is strongly indicated. The fossil record of pangolins would seem to support a European origin for the modern forms, with subsequent dispersal into sub-Saharan African and then to southern Asia, and the phylogeny produced in this analysis is consistent with such a scenario.

Morphology-based phylogeny. The morphological data matrix yielded one island of 4928 shortest trees, each 49 steps long (CI = 0.69; CI’ = 0.61 excluding autapomorphies), and a strict consensus phylogeny that resolved only 5 of 22 potential nodes within Clermontia (Fig. 1A). Seventeen of 27 characters were parsimony-informative.
