'Wing fingers' provide evolutionary evidence that birds are descended from a group of dinosaurs

In recent articles in Live Science and Science Ann Burke, chair and professor of biology, comments on a new study links the “wing fingers” of baby chicks with the digits of a particular group of dinosaurs. The study lends evidence to the theory that birds evolved from a group of carnivorous dinosaurs that roamed the earth 150 million years ago. Burke had been co-author of a previous study in 1997 that established the hypothesis and provided early evidence to support it.
