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.

Discussion of Phylogenetic RelationshipsTello et al. (2009) found Tyrannus to be paraphyletic to Griseotrannus and Empidonomus, but support was weak. Only two species of Tyrannus have been sampled, and clarification must await further data.
