From the shape of the nests birds build to the color of their feathers, technology is turning theories dating back to Darwin on their head. Biologist Jordan Price, of St Mary’s College of Maryland, has mapped the genes of both ancient and more recently derived bird species. He tells us why domed bird nests evolved into the widespread bowl shape, why the color of feathers might be more about camouflage than attraction, and what scientists got wrong when studying the differences between female and male birds.
