Orders
Glires (Latin glīrēs, dormice) is a clade consisting of rodents and lagomorphs (rabbits, hares, and pikas). This hypothesis that these form a monophyletic group has been long debated based on morphological evidence, although recent morphological studies strongly support monophyly of Glires (Meng et al., 2003). Data based on nuclear DNA support Glires as a sister of Euarchonta to form Euarchontoglires (Murphy et al. and Madsen et al. 2001), but some genetic data from both nuclear and mitochondrial DNA have been less supportive (Arnason et al. 2002). A study investigating retrotransposon presence/absence data unambiguously supports the Glires hypothesis (Kriegs et al. 2007).

The Paleocene, "early dawn of the recent", is a geologic epoch that lasted from 65.5 ± 0.3 Ma to 55.8 ± 0.2 Ma (million years ago). It is the first epoch of the Palaeogene Period in the modern Cenozoic era.

Kangaroo rats, genus Dipodomys, are small rodents native to North America. The name derives from their bipedal form: they hop like tiny kangaroos.

Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. Scientific classification also can be called scientific taxonomy, but should be distinguished from folk taxonomy, which lacks scientific basis.
