The study, published this week in Development, demonstrates striking similarities in the genetic mechanism used to pattern gill arch appendages (called branchial rays) and fins / limbs.
«Branchial rays will figure prominently in the story of the evolutionary origin of vertebrate animal appendages, either by shedding light on the evolutionary antecedent of paired fins / limbs, or by teaching us about the genetic mechanisms that animals can use to invent new appendages,» Gillis says.
Ongoing studies comparing the function of other genes during branchial ray and fin / limb development will help to resolve this.
