Could Giant Kangaroos Hop Scaling of tendon geometry and skeletal features
Meeting Abstract 73.4 Tuesday, Jan. 6 Could Giant Kangaroos Hop? Scaling of tendon geometry and skeletal features. MCGOWAN, C.P.; Univ. of Texas at Austin cpmcgowan@mail.utexas.edu Large species of Macropodoidea, the superfamily containing kangaroos and wallabies, have the amazing ability to decouple oxygen consumption from speed. This is largely due to the capacity to store and return increasing […]

Kinethmoid-Mediated Premaxillary Protrusion Development of a Complex Trait Provides Clues to Its Evolution
Meeting Abstract 72.3 Tuesday, Jan. 6 Kinethmoid-Mediated Premaxillary Protrusion: Development of a Complex Trait Provides Clues to Its Evolution STAAB, KL*; HERNANDEZ, LP; George Washington University kstaab@gwmail.gwu.edu Studies on the evolution of complex biological systems are difficult since their construction cannot be observed over an evolutionary timescale. Complex traits are defined as consisting of multiple elements, often […]

Constructing a complex morphological novelty Insights from growth, development, and genetics of the cypriniform Weberian apparatus
Meeting Abstract 72.2 Tuesday, Jan. 6 Constructing a complex morphological novelty: Insights from growth, development, and genetics of the cypriniform Weberian apparatus BIRD, Nathan C.*; HERNANDEZ, L. Patricia; George Washington University; George Washington University nbird@gwmail.gwu.edu Vertebrate morphologists have long examined hearing capabilities in fishes, with particular emphasis on so-called hearing specialists. However, less emphasis has been placed […]
