Some dinosaurs could fly before they were birds

New research using the most comprehensive study of feathered dinosaurs and early birds has revised the evolutionary relationships of dinosaurs at the origin of birds. An international team of researchers, including McGill University Professor Hans Larsson published their findings in the journal Current Biology. The team pored over fossils, developed a novel analytical pipeline to search for evolutionary trees, and estimated how each species may have crossed the stringent thresholds for powered flight.
