Dissertation Research: Phylogeny of New World Cricetid Rodents Using DNA Hybridization

艾伦·迪克曼在约翰医生的监督下工作 威斯康星大学麦迪逊分校的基尔希正在使用 DNA-DNA杂交技术， 仓鼠科啮齿动物的进化历史， 测试与进化的克里思和模式有关的假设， 这个多样而重要的哺乳动物家族家庭 包括73属369种。虽然 该群体的进化史是有争议的，它似乎 分为北美和南美两组。这 分子水平的研究将测试关于 北美和南美血统的关系， 与旧大陆形态的关系，部落的关系 在家庭中，等等。这项研究将大大增加我们的 了解新大陆生物多样性的起源， 尤其是哺乳动物的。

Allan Dickerman, working under the supervision of Dr. John Kirsch at the University of Wisconsin-Madison, is using the technology of DNA-DNA hybridization to reconstruct the evolutionary history of rodents in the family Cricetidae and to test hypotheses concerned with the tempo and mode of evolution in this diverse and important family of mammals. The family comprises 369 species divided into 73 genera. Although the evolutionary history of the group is contentious, it appears to be divided into North American and South American Groups. This molecular level study will test hypotheses about the relationships of the North and South American lineages, relationships with Old World forms, relationships of tribes within the family, etc. The study will significantly increase our understanding of the origin of biodiversity within the New World, especially that of mammals.
