This research will focus on the evolution and diversity of labroid fishes - including cichlids, labrids (wrasses and parrotfish), pomacentrids (damselfishes) and embiotocids (surfperch). At over 3,000 species, these are among the most successful and diverse groups of bony fishes. Hypotheses will be tested about the effect of major innovations found in the pharyngeal jaws of these fishes on speciation rate, morphological diversity, and ecological diversity. The research has two major components. DNA sequence from 9 genes and 650 species will be obtained to determine the phylogenetic relationships between labroids and other fishes. The resulting phylogenetic trees will be used as the basis for making comparisons of diversity between groups that possess the modified pharyngeal jaw, and close relatives that lack the specialization.The major contribution of this research will be to improve our understanding of how breakthroughs in functional design impact the evolutionary success of lineages. New insights will be gained into evolutionary relationships within one of the least understood branches of the bony-fish tree of life. Training and mentoring will be provided for two post-doctoral researchers and one graduate student. Teaching modules will be developed from this research for undergraduate and graduate courses. An undergraduate internship program will be developed to recruit students from disadvantaged backgrounds into research opportunities provided by this project.

这项研究将重点关注实验室鱼类的进化和多样性，包括丽鱼科鱼类、实验室鱼类（濑鱼和鹦嘴鱼）、pomacentrids（雀鲷）和embiotocids（冲浪鲈）。这些鱼类共有 3,000 多种，是最成功、最多样化的硬骨鱼群之一。将测试这些鱼类咽颌中发现的重大创新对物种形成率、形态多样性和生态多样性的影响的假设。该研究有两个主要组成部分。将获得来自 9 个基因和 650 个物种的 DNA 序列，以确定 Labroids 和其他鱼类之间的系统发育关系。由此产生的系统发育树将用作比较具有修饰的咽颌的群体和缺乏特化的近亲之间的多样性的基础。这项研究的主要贡献将是提高我们对功能设计突破的理解影响谱系进化的成功。人们将对硬骨鱼生命树中最不为人所知的分支之一的进化关系获得新的见解。将为两名博士后研究人员和一名研究生提供培训和指导。教学模块将从这项研究中开发出来，用于本科生和研究生课程。将制定本科生实习计划，招募来自弱势背景的学生参与该项目提供的研究机会。
