  1. Molecular Epigenetics in Evolution and Development

    Lewis, James JosephVirginia Tech2010

    The dominantly held view in evolutionary theory focuses on gradual or punctuated change, primarily via natural selection, as the mechanism by which novel traits arise and evolution occurs. Noticeably absent from this portrayal of evolution is mention of the conservation of general characteristics, …

  6. Evolution and Development of Pigmentation Patterns in East African Cichlid fishes

    Hickey, AaronUniversity of Cambridge2024

    Understanding the origin of novel phenotypic diversity remains a fundamental question in evolutionary genetics. This thesis aims to address the origin and diversification of novel traits by integrating population genomics and developmental genetics techniques. Using East African cichlid fishes as a …

  9. UNCOVERING THE EVOLUTION AND DEVELOPMENT OF A NOVEL ABDOMINAL APPENDAGE IN BLACK SCAVENGER FLIES (SEPSIDAE: DIPTERA)

    GOWRI D/O RAJARATNAM2019

    I explore the evolution and development of a novelty in sepsid flies where males have recently evolved an elaborate brush-like appendage on the fourth abdominal segment that varies in shape and size across the family. A comparative analysis showed that male sepsids pay for more ornate 4th sternite …
