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
This superfamily was erected by Cracraft et al. (2004) to cover a clade of four families removed from Sibley and Ahlquist’s (1990) Sylvioidea. It includes Troglodytidae (wrens), Polioptilidae (gnatcatchers), Certhiidae (treecreepers), and Sittidae (nuthatches) (Barker et al. 2002, 2004; Ericson and Johansson 2003; Beresford et al. 2005). Within this clade, Sittidae is basal and Troglodytidae and Polioptilidae are sister taxa (Sibley and Ahlquist 1990; Harshman 1994; Sheldon and Gill 1996; Ericson and Johansson 2003; Barker 2004; Alström et al. in press; but see Barker et al. 2002, 2004).
