Science 304:90-3. 2004..The functional diversity of the earliest known limbs includes several different kinds of appendage design.

J Morphol 270:628-43. 2009..Finally, we suggest that the unique presence of certain visceral skeletal elements in chondrichthyans make oviparous chondrichthyans an ideal system for addressing questions of endoskeletal axial patterning during development... - The evolution of gnathostome development: Insight from chondrichthyan embryologyJ Andrew Gillis
Department of Organismal Biology and Anatomy, University of Chicago, Chicago, Illinois, USA
Genesis 47:825-41. 2009..These findings fuel novel hypotheses of developmental genetic homology, and demonstrate how comparative studies of gnathostome development can provide insight into the evolutionary processes that underlie morphological diversity... - Shared developmental mechanisms pattern the vertebrate gill arch and paired fin skeletonsJ Andrew Gillis

J Morphol 265:87-101. 2005..mexicanum. However, apoptotic cells that may play a role in digit ontogeny occur in the limbs of D. aeneus, thereby suggesting that programmed cell death has evolved as a developmental mechanism at least twice in tetrapod limb evolution... - Pectoral fin and girdle development in the basal actinopterygians Polyodon spathula and Acipenser transmontanusMarcus C Davis

J Morphol 262:608-28. 2004..In contrast, teleost fins generally possess relatively small endoskeletal radials that articulate with the dermal fin skeleton terminally, with little or no proximodistal overlap... - Sonic hedgehog function in chondrichthyan fins and the evolution of appendage patterningRandall D Dahn
Department of Organismal Biology and Anatomy, The University of Chicago, Chicago, Illinois 60637, USA
Nature 445:311-4. 2007..These studies demonstrate that some aspects of Shh function are deeply conserved in vertebrate phylogeny, but also highlight how the evolution of Shh regulation may underlie major morphological changes during appendage evolution... - An autopodial-like pattern of Hox expression in the fins of a basal actinopterygian fishMarcus C Davis
Department of Organismal Biology and Anatomy, The University of Chicago, Chicago, Illinois 60637, USA
Nature 447:473-6. 2007..These data show that aspects of the development of the autopod are primitive to tetrapods and that the origin of digits entailed the redeployment of ancient patterns of gene activity... - The cranial endoskeleton of Tiktaalik roseaeJason P Downs
