The different steamer duck species vary in their morphology, representing a continuum between the conditions allowing flight and those resulting in flightlessness. Whereas most transitions from flight to flightlessness have happened relatively deep in bird evolution, the steamer ducks represent a rare case in which this process can be studied while it is still in action.&nbsp;The study identifies two narrow candidate genomic regions implicated in the morphological changes that led to flightlessness. The strongest association is with DYRK1A, a gene that when knocked out in mice leads to alterations in growth and bone morphogenesis.<\/p>\n<p>Here is a commentary on the paper from <a href=\"https:\/\/www.nature.com\/articles\/d41586-019-02234-y\">Nature<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new paper in Evolution&nbsp;by research associate Leonardo Campagna explores the genomic mechanisms that have led to the evolution of flightlessness in the Patagonian steamer ducks.
