Description
Published cladistic reconstructions of galagonid phylogeny based on morphological, behavioral, and genetic data have had few elements in common. A recent molecular study indicated that 2 of the 3 generic groupings derived from morphological data were not consistent with tree topologies constructed from the analysis of mitochondrial DNA sequences. In this study, we compiled and analyzed a data set based on craniodental morphology in 13 galagonid and 8 outgroup taxa, comprising 3 dwarf-lemur and 5 loris species, and subjected it to cladistic analysis. Our aim was not only to generate a new phylogenetic hypothesis based on these data, but also to investigate the conditions under which congruence could be achieved between these results and those obtained previously. The data set was found to be highly sensitive to the choice of outgroup, with the lorises showing high interspecific variability in cranial structure. Congruence between the craniodental and molecular trees could be achieved only if Arctocebus was used as the outgroup and two characters were preferentially weighted. Further progress in the reconstruction of galagonid phylogeny will require seeking consensus in a variety of other data sets, including postcranial morphology, behavior, and additional gene sequences. The effect of different outgroups on molecular analysis needs attention. © 2002 Wiley-Liss, Inc.
