Eurylaimides
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.

The Old World suboscines are a small group with only 50 species in four families, in contrast to the New World suboscines with over a thousand. The Old World suboscines are only slightly misnamed, as they have a single New World member, Sapayoa aenigma (Chesser 2004). And it may be that neither of the two major families is monophyletic. Pittidae (pittas) may be paraphyletic to Sapayoa, with a larger taxon sample necessary to resolve this question (Fjeldså et al. 2003, Chesser 2004). Eurylaimidae (broadbills) is paraphyletic to Philepittidae (asities) (Prum 1993; Irestedt et al. 2001; Barker et al. 2002, 2004; Beresford et al. 2005).
