Department of Biology Professors Rebecca Kimball (opens in new tab) and Edward Braun (opens in new tab) were part of a study led by University of Michigan researchers that has identified important changes in birds’ genomes sparked by the mass extinction, called the end-Cretaceous mass extinction event, that led to the extinction of dinosaurs, ultimately contributing to the incredible diversity of living birds.

The Eurasian Hoopoe, Upupa epops, is a member of the bird group Coraciimorphae. Authors identify this group of birds and others as having close ties to the end-Cretaceous mass extinction that occurred in the wake of the Chicxulub asteroid impact approximately 66 million years ago.
