Let's talk about this for a minute.
Those that study such things believe the last common ancestor of all currently living species of birds lived 85 to 95 million years ago during the late Cretaceous period. That single species, whatever it was, had probably already developed most of features common to modern birds including flight. There were probably other related species living at the same time with similar features such as flight that evolved along divergent paths, but most of the features common to modern birds all date back to that single species that lived 85 to 95 million years ago.
Quote:i.e. birds that are only distantly related to each other evolved similar features to each other (such as flight) independently of each other.
