A recent publication by 105(!) authors provides the first whole-genome analysis of key bird families representing all living Orders, and with it a more fully fleshed-out sense of the origins and timing of the evolution of modern birds. The bird family tree, informed by the connectedness of near relatives and distant relations, including previously hard to place groups, is now resolved (and can be viewed here).
There is much to digest. Here are some highlights:
Birds are dinosaurs, as most (but not all!) scientists agree.
