How the Galápagos cormorant got its tiny wings
Faulty genes that hamper cell chatter robbed birds of flight
NO FLY ZONE Galápagos cormorants’ wings have dwindled so much over the last 2 million years that the birds can no longer get off the ground. Researchers now have genetic evidence implicating faulty cellular antennas, called primary cilia, in shrinking the wings.
