The origins of continental biotas are much less well-known than are those of islands. This results in large part from the complexity of continental faunas. The PI intends to develop rigorous phylogenies for three widespread and diverse genera of rodents (Perognathus, Chaetodipus and Onychomys), and to infer patterns of migration, speciation, and extinction based on those phylogenies. The primary tools for development of the phylogenies are parsimony analysis based on mtDNA sequences. This will also permit the PI to explore processes of speciation.

大陆生物化石的起源远不如 是那些岛屿。 这主要是由于 大陆动物群的复杂性。 PI计划开发 严格的亲缘关系，为三个广泛和不同的属， 啮齿动物（Perognathus，Chaetodipus和Onychomys），并推断 迁移、物种形成和灭绝的模式， 精灵们。 发展生物多样性的主要工具 是基于mtDNA序列的简约分析。 这也将 允许PI探索物种形成的过程。
