AbstractEF-0334961A grant has been awarded to Dr. Maureen Kearney and Dr. Olivier Rieppel of the Field Museum of Natural History to study the evolutionary history of squamate reptiles (lizards and snakes). With over 7,700 species, squamates are the second largest group of terrestrial vertebrates. Many critical questions in squamate evolution remain unresolved, such as identification of the most primitive lineage of squamates, the origin of snakes, and the relationships of venomous snakes to other snake lineages. An international team of eight investigators from diverse institutions (Brigham Young University, Field Museum of Natural History, San Diego State University, State University of New York-Stony Brook, University of Adelaide, University of Texas-Austin, and Yale University) will collaborate to resolve squamate relationships. Anatomical data from living and fossil forms will be combined with DNA sequences from 50 genes for 142 representative squamate species. Anatomical data will be obtained using traditional methods, as well as new technology such as high resolution X-ray CT scanning. DNA data will be generated by incorporating new tools and databases from recent vertebrate genome projects. Drs. Kearney and Rieppel will be responsible for the collection of anatomical data for extant and fossil species, and Dr. Jessica Maisano (University of Texas-Austin, subcontracted through the Field Museum) will be responsible for the CT-scanning portion of the research. Understanding the evolutionary history of squamate reptiles is critical for a complete picture of vertebrate evolution and ecology. Venomous snakes pose an important threat to human safety in many parts of the world, and identification is critical for effective treatment; an innovative web-site will be produced allowing snakebite victims and medical workers to identify the venomous snakes in their area. Postdoctoral researchers and students will be involved in all aspects of this project; thus the training of many future biologists and educators will be supported.

菲尔德自然历史博物馆的Maureen Kearney博士和Olivier Rieppel博士获得了一笔研究有鳞爬行动物（蜥蜴和蛇）进化史的资助。 有鳞动物有超过7,700种，是陆地脊椎动物的第二大类群。 有鳞动物进化中的许多关键问题仍然没有解决，例如最原始的有鳞动物谱系的识别，蛇的起源，以及毒蛇与其他蛇谱系的关系。 一个由来自不同机构（杨百翰大学、菲尔德自然历史博物馆、圣地亚哥州立大学、纽约州立大学-石溪分校、阿德莱德大学、德克萨斯大学-奥斯汀分校和耶鲁大学）的8名研究人员组成的国际团队将合作解决鳞片关系。 来自活的和化石形式的解剖数据将与来自142个代表性有鳞动物物种的50个基因的DNA序列相结合。 将使用传统方法以及高分辨率X射线CT扫描等新技术获得解剖数据。 DNA数据将通过整合最近脊椎动物基因组计划的新工具和数据库来生成。Kearney和Rieppel博士将负责收集现存物种和化石物种的解剖数据，Jessica Maisano博士（德克萨斯大学奥斯汀分校，通过菲尔德博物馆分包）将负责研究的CT扫描部分。了解有鳞爬行动物的进化历史对于了解脊椎动物进化和生态学的全貌至关重要。 毒蛇对世界许多地方的人类安全构成重大威胁，识别毒蛇是有效治疗的关键;将建立一个创新网站，使蛇咬伤受害者和医务工作者能够识别所在地区的毒蛇。 博士后研究人员和学生将参与该项目的各个方面;因此，将支持许多未来生物学家和教育工作者的培训。
