Morphological innovation through gene regulation: an example from Devonian Onychodontiform fish

Campbell, Kenton; Barwick, Richard


The recent development of novel phenotypic designs by changes in gene regulation has been extensively discussed within the context of evolution and development. The fossil record shows many new designs (or body plans) which appear rapidly at various stratigraphic levels. One example of this is the arrival of the lobe finned fish in the Early Devonian, when a great variety of new forms appeared. These include the dipnoans, the onychodontids, the porolepiforms and the osteolepiforms, which differ...[Show more]
