This tree diagram shows the relationships between several groups of organisms.
The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.close box
Muscicapoidea is a superfamily of the order Passeriformes, erected by Sibley and Ahlquist (1990) to include the thrushes, Old World flycatchers, and their relatives. The group has a worldwide distribution.
The most difficult question is whether Bombycillidae (waxwings, silky flycatchers, palmchat) belongs to this superfamily. No analysis has been conclusive, but several have given weak support (Sibley and Ahlquist 1990; Barker et al. 2002, 2004; Cibois and Cracraft 2004) and the combination of independent analyses seems to offer strong support. Monophyly of the rest of Muscicapoidea is clear (Sibley and Ahlquist 1990; Harshman 1994; Barker et al. 2002, 2004; Ericson and Johansson 2003; Cibois and Cracraft 2004; Voelker and Spellman 2004; Alström et al. in press).
The relationships of Hypocoliidae are uncertain. It has never been included in any formal phylogenetic analysis. Traditionally, however, it has been placed next to Bombycillidae, and that's where it appears here.
Relationships among the five families Sturnidae (starlings), Mimidae (mimic thrushes) Cinclidae (dippers), Turdidae (thrushes), and Muscicapidae (sensu stricto — Old World flycatchers) are also contentious, but a strong case can be made for the topology shown above (Sibley and Ahlquist 1990; Barker et al. 2002, 2004; Cibois and Cracraft 2004; Beresford et al. 2005; Fuchs et al. in press). An alternative arrangement in which Cinclidae is sister to the sturnid-mimid clade is supported only weakly, and in a single analysis, though the relationship between Turdidae and Muscicapidae is also supported by parsimony jackknifing (Ericson and Johansson 2003). Voelker and Spellman (2004) show a substantially different topology, in which Muscicapidae is basal, but contradictory nodes again have weak support.
Two additional genera form a polytomy with Sturnidae and Mimidae (Cibois and Cracraft 2004). Buphagus (oxpeckers) is traditionally considered part of Sturnidae. Rhabdornis is a genus of previously uncertain relationships, sometimes placed in Certhiidae or Timaliidae (Sibley and Monroe 1990).
