Markers of the wrists and digits in the limb of a mouse (left) are present in fish and demarcate the fin rays (right). The wrist and digits of tetrapods are the cellular and genetic equivalents of the fin rays of fish.
As I recall, there was a massive controversy after the discover of the "Tiktaalik" fossil and similar fossils. This study goes into the genetics of the fin adaptations leading to feet that the morphology of Tiktaalik shows.

Long John Silver’s could probably offer some insight on the issue. I remember they used to sell Fish Fingers.

Research could in turn help uncover the mystery behind chicken fingers, and perhaps even chicken nuggets.

Research could in turn help uncover the mystery behind chicken fingers, and perhaps even chicken nuggets....and from there, they can try to unravel the mystery of how buffalo wings came into being.
