Abstract: Out on a fin A key question in the evolution of limbs and fins is the generality of the genetic mechanism underlying their development. Following reports that shark fins developed without Sonic hedgehog (Shh), a gene elsewhere seen as crucial to the process, Dahn et al. re-investigated the problem. They find that Shh is indeed involved in shark fin development, boosting its credentials as a key component of anteroposterior patterning of vertebrate fins and limbs.
