New clues that the origin of plumage goes back to at least 250 million years ago

An article published in the journal “Trends in Ecology & Evolution” reports new clues about the origin of plumage that confirm that it evolved starting from about 250 million years ago among some life forms that survived the devastating mass extinction that occurred at the end of Permian period. A team of researchers coordinated by the British University of Bristol combined information regarding fossils with others obtained through molecular biology analysis to obtain a conclusion that confirms a hypothesis made after the discovery of feathered pterosaurs.
