Of chicken wings and frog legs: a smorgasbord of evolutionary variation in mechanisms of tetrapod limb development.

Abstract excerpt

The tetrapod limb, which has served as a paradigm for the study of development and morphological evolution, is becoming a paradigm for developmental evolution as well. In its origin and diversification, the tetrapod limb has undergone a great deal of remodeling. These morphological changes and other evolutionary phenomena have produced variation in mechanisms of tetrapod limb development. Here, we review that...
