Evolution of the Animal Face from Principles to Mechanisms
Meeting Abstract 25-4 Thursday, Jan. 5 14:15 – 14:30 Evolution of the Animal Face: from Principles to Mechanisms. ABZHANOV, ARKHAT; Imperial College London and Natural History Museum a.abzhanov@imperial.ac.uk Understanding the origins of animal diversity is one of the chief challenges to the modern biological sciences. We aim to reveal molecular mechanisms underlying evolutionary processes that generate morphological […]

Development Shapes Mosaic Evolution in Bird Skulls
Meeting Abstract 26-5 Thursday, Jan. 4 15:00 – 15:15 Development Shapes Mosaic Evolution in Bird Skulls FELICE, RN*; GOSWAMI, A; University College London ryanfelice@gmail.com Mosaic evolution describes the presence of a mixture of derived and pleisomorphic characteristics. This condition can be generated as a result of interrelated clusters of traits, or modules, evolving with different tempo and […]

Adaptive Landscape of Eye Size Evolution in Geckos
Meeting Abstract 26-1 Thursday, Jan. 4 14:00 – 14:15 Adaptive Landscape of Eye Size Evolution in Geckos SCHMITZ, L*; HIGHAM, TE; Claremont McKenna, Scripps, and Pitzer Colleges; UC Riverside ecomorph@gmail.com Visually guided organisms depend on their ability to collect information about their environment in order to capture prey, avoid predation, and find mates. Visual performance therefore represents […]
