First, I would like to give deep thanks to my adviser Philip A. Hastings who gave me the opportunity to pursue my research interests in fish evolution, provided helpful advice on research, and respected me as though I were a colleague. As an international student, I especially appreciate his understanding of our cultural difference and his unlimited patience while correcting both my spoken and written English. Many thanks are also due to my other committee members: Ron Burton, Richard Rosenblatt, Greg Rouse, and Chris Wills. Ron Burton and his lab (Kristen Gruenthal, Chris Ellison, and others) provided insight whenever I struggled in molecular experiments or with the sequencing machine. Greg Rouse and his lab (Nerida Wilson, Danwei Huang, and others) helped me with the most up-to-date analytical software. Richard Rosenblatt taught me how to do good scientific writing. A special thanks goes to my qualifying committee member Nancy Knowlton and her lab (Flavia Nunes, Laetetia Plaisance,
