(Robert Lewis) 1928 Packard, Robert Lewis Speciation and Evolution of the Pygmy Mice, Genus Baiomys Produced by Chris Curnow, Tom Cosmas, Joseph Cooper and the Online Distributed Proofreading Team at http://www.pgdp.net "Speciation and Evolution of the Pygmy Mice, Genus Baiomys" by Robert L. Packard is a scientific publication written in the mid-20th century. This work primarily focuses on the study of pygmy mice, their taxonomy, geographic distribution, and the evolutionary trends seen within the genus Baiomys, which includes various fossil and living species of these rodents. At the start of the publication, the author introduces the genus Baiomys, detailing its geographic range stretching from Central America to the southwestern United States, with a significant presence in Mexico. The opening discusses their historical recognition within scientific literature, sparking interest in understanding the interspecies relationships and geographic variations of different pygmy mouse species. Packard outlines the objectives of this study, including a comprehensive analysis of their morphological characteristics, variety within species, and establishing linkages among extinct and extant members of the genus. The early sections set the stage for a thorough examination of pygmy mouse evolution and speciation.
