PALEONTOLOGY:
Enhanced: From Fins to Fingers

Jennifer A. Clack

The transition from fish to tetrapod, and from fins to fingers, began during the Devonian period about 370 to 360 million years ago. In her Perspective, Clack discusses the implications of a new fossil find of a humerus from a Devonian tetrapod that sheds light on the anatomical and functional changes taking place in the tetrapod lineage during this period (Shubin et al.).
