Murid rodentsScott J. Steppan
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
Recent molecular studies using more slowly evolving nuclear genes have modified some traditional groupings based on morphology and greatly increased our confidence in most of the relationships. This muroid tree is based primarily on the nuclear DNA phylogenies of Steppan et al. (2004), Jansa and Weksler (2004), and Michaux et al. (2001) as well as Robinson et al. (1997) and Michaux and Catzeflis (2000). The classification used here follows Steppan et al. (2004) and differs from the more commonly used taxonomy of Musser and Carleton (1993) by recognizing more than a single family within Muroidea. Musser and Carleton (1993) chose to not subdivide the superfamily because of uncertainty about phylogenetic relationships among the many subfamilies. Strong concordance among many molecular phylogenies has greatly improved that situation.
