Silurana (Xenopus) tropicalis as a model system for the evolution of odontogenesis
Meeting Abstract 135.5 Monday, Jan. 7 Silurana (Xenopus) tropicalis as a model system for the evolution of odontogenesis GRIECO, TM; University of California, Berkeley grieco@berkeley.edu The highly conserved developmental mechanisms of odontogenesis illuminate the ways in which vertebrates have created highly adaptive and morphologically variable phenotypes from similar genetic underpinnings. The frog model Silurana (Xenopus) tropicalis, with […]

Neural crest derivation of the bony skull of the Mexican axolotl and its implications for vertebrate skull evolution
Meeting Abstract 135.2 Monday, Jan. 7 Neural crest derivation of the bony skull of the Mexican axolotl and its implications for vertebrate skull evolution PIEKARSKI, N.*; HANKEN, J.; Harvard University; Harvard University npiekarski@oeb.harvard.edu Cartilages and bones of the craniate skull are derived from two embryonic sources, neural crest and mesoderm. Contributions of these tissues to the skull […]
Are swimbladders inverted lungs Evidence from developmental genetics
Meeting Abstract 135.6 Monday, Jan. 7 Are swimbladders inverted lungs? Evidence from developmental genetics CASS, AN*; MCCUNE, AR; Cornell University; Cornell University anc24@cornell.edu The homology of lungs and swimbladders has been accepted to varying degrees by the great morphologists of the 19th and 20th centuries. We have recently shown that a shared developmental regulatory network underlies the […]
A dual embryonic origin of the vertebrate pharyngeal skeleton
Meeting Abstract 135.4 Monday, Jan. 7 A dual embryonic origin of the vertebrate pharyngeal skeleton SEFTON, E.M.*; PIEKARSKI, N.; HANKEN, J.; Harvard University esefton@oeb.harvard.edu The pharyngeal-arch skeleton is a hallmark of vertebrates. In basal taxa, it supports the gills and muscles of the pharynx, whereas in more derived groups it surrounds the larynx and trachea. That most […]
