The Evolution of Paired Fins and the Origin of Tetrapod Limbs
The analysis of limb origins touches on many central issues of evolutionary morphology. The origin of limbs is a major adaptive transformation, encompassing developmental, functional, and ecological modifications. Adaptive evolution of the structure and function of paired appendages involves the genetic modification of developmental processes. The study of this transformation, then, entails a synthesis of genetic, developmental, and functional approaches.
