"Fins to Limbs: The Forgotten Story of Fin Rays" with Neil Shubin, Professor, The University of Chicago.

Abstract: The transformation of fins into limbs entailed many changes, most notable the origin of digits and the loss of the fin rays.  Most studies of this shift have focussed on the origin of wrists, ankles, fingers and toes, and changes to the rays has largely been ignored.  30 years of Devonian collecting has yielded diverse and high quality fossils that allow us to assess this issue.  Major changes to the fin rays were underway before the origin of limbs. Moreover, developmental evidence reveals that the origin of digits and the loss of rays may linked during embryogenesis.
