Mass extinction 66 million years ago triggered rapid evolution of bird genomes.

Study examined evolutionary trajectory of all major bird groups and found evidence of "genomic fossils" in birds' DNA that mark critical evolutionary steps as birds evolved into more than 10,000 living species.

The research is published as an open-access article in the journal Science Advances .

Study furthers understanding of dramatic biological impacts of mass extinction events.

Mass extinction that wiped out the giant dinosaurs was one of the most biologically impactful events in the entire history of our planet.

By relaxing the typical assumptions used in evolutionary biology, the researchers say they are building more nuanced insight into the sequence of events that occurred in the early history of birds.
