There Was a Big Bang for Birds: A sweeping new study tells a long genetic tale

Time: If there’s a factory where birds are built, the workers were clearly smoking something the day they designed the hummingbird. And the ostrich. And the toucan. Imagine, too, the pitch meeting for the parrot, (“Let’s make this one talk!”), or the peacock (“So we got this crate of feathers…”).

This finding results from the work of hundreds of scientists at 80 labs and universities across 20 countries, done with the help of bird tissue collected from labs and museums around the world. Those specimens were sent to the Genome Tissue Institute in Beijing, where the basic sequencing was conducted. The first and most basic conclusion the investigators reached was a big one. “This confirms that there was a very rapid radiation and that major lineages of birds were in existence 5 to 6 million years after the extinction event,” says Joel Cracraft, an avian systemicist at the American Museum of Natural History in New York and a contributor to the papers. “They were very widely distributed as well.”
