I want to know the answer to the following question:
What was the earliest divergence within the Neognathes?
All the background I'm provided with is that "The earliest divergence within the Neognathes was that of the Galloanserae, the superorder containing the Anseriformes (ducks, geese, swans and screamers) and the Galliformes (the pheasants, grouse, and their allies, together with the mound builders and the guans and their allies).". Is that enough to answer the question?
