FLIGHTLOSS | The Genomic Underpinnings of Convergent Evolution: Repeated Loss of Flight in Island Rails, the Greatest Avian Colonizers

Summary
Convergent evolution—when similar changes occur in independent lineages—may be caused by similar selection pressures resulting in the same adaptations. This is exemplified by the evolution of echolocation in bats and whales, and the evolution of flight in insects, bats, and birds. The phenotypic convergence in major traits is less well-understood at a molecular level, and cases of genomic convergence are rare. In this action, I will focus on rails, a family of birds that is outstanding in two respects: (1) They are extremely successful dispersers and have colonized hundreds or thousands of islands by flight. (2) If island conditions did not require a volant lifestyle, over time the developmental resource investment into the flight apparatus is reduced, and the flight capability often eventually entirely lost. The loss of flight has occurred repeatedly and independently at least 30 times, often over short evolutionary time scales (
