BirdNote: An Avian Big Bang
Many scientists believe that the demise of the dinosaurs began when an asteroid struck the earth 66 million years ago. Some dinosaurs survived, and among them were the early ancestors of birds.
Recently an international research team sequenced the genomes of 45 birds of diverse lineages. The results revealed a surprising discovery: the common ancestor of today’s birds — among them warblers, parrots, woodpeckers, falcons, and owls — was a top-of-the-food-chain carnivore!
