Two genes that are important for the diverse colors and patterns of warbler plumage have evolved through two very different processes, according to a new study led by Penn State researchers. These evolutionary processes could help explain the rapid evolution of these songbirds into so many unique species.
“Wood warblers are an incredibly colorful and diverse group of birds, with more than a hundred species in total,” said Marcella Baiz, postdoctoral researcher at Penn State and first author of the…
