Scallops in the family Pectinidae are a diverse group of marine bivalves that includes over 300 species. As a group, scallops support important fisheries and are the focus shellfish farming operations worldwide. Members of the family exhibit wide variation in such behaviors as swimming and mode of reproduction. Despite their interesting biology and economic importance, scallop diversity and evolutionary relationships are poorly understood. The goals of this research project are to: 1) generate hypotheses for the evolutionary relationships of scallops using DNA sequence and morphological data; 2) develop stable classification of scallops reflective of these relationships; and 3) use this information to better understand the evolution of scallop morphological characters, behaviors, and life history traits.Through this research, important insight will be gained into a fundamental component of the evolutionary process: the origin of complex characters. In addition, this work will provide training to a postdoctoral associate and graduate and undergraduate students in all activities during the production of a modern systematic treatment scallops. Besides peer-reviewed publications and dissemination of results at scientific meetings, an interactive web-based resource (the Pecten Resource Web Site) will be developed, thus improving communication among a wide range of users, including scallop farmers, malacologists, evolutionary biologists, ecologists, and shell enthusiasts.

扇贝属于扇贝科（Pectinidae），是海洋双壳类的一个多样化的类群，包括300多个物种。作为一个群体，扇贝支持重要的渔业，是全球贝类养殖的重点。 家庭成员在游泳和繁殖方式等行为上表现出广泛的差异。尽管它们有着有趣的生物学和经济重要性，但人们对扇贝的多样性和进化关系知之甚少。 本研究的目标是：1）利用DNA序列和形态学数据对扇贝的进化关系提出假设; 2）建立反映这些关系的稳定的扇贝分类; 3）利用这些信息更好地了解扇贝的形态特征、行为和生活史性状的进化。通过本研究，重要的洞察力将获得到进化过程的一个基本组成部分：复杂字符的起源。 此外，这项工作将提供培训，以博士后助理和研究生和本科生在所有活动期间生产的现代系统处理扇贝。除了同行审查的出版物和在科学会议上传播成果外，还将开发一个互动的网上资源（扇贝资源网址），从而改善广大用户之间的交流，包括扇贝养殖者、软体动物学家、进化生物学家、生态学家和贝壳爱好者。
