The international team researchers used DNA-sequencing data — when available — to show the evolutionary relationships between living bird species. It also shows bird speciation rates across time and geographies.

“We have built the first ever family tree showing the evolutionary relationship among the species of birds. We used fossils and genetic data to estimate the ages of all the different branches of the bird tree so that we could assess how diversity has accumulated through time,” said co-author Gavin Thomas of the University of Sheffield in a statement. “Our work is indebted to researchers from museums and universities who have collected astounding amounts of genetic data from birds around the world.”
