Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

Not exactly what's being said. Although gastornithids and dromornithids forming Gastornithiformes was pretty well supported, the position of Vegavis was inconsistent, and consistently poorly supported. It's somewhere in Galloanserae outside of crown Anseriformes/Galliformes, but where exactly is hard to say for now. Also notable is that there isn't particular reason to group Gastornithiformes with Anseriformes rather than Galliformes. The paper concludes there's four branches within Galloanserae (Anseriformes, Vegavis, Gastornithiformes, and Galliformes), but how they're interrelated remains unresolved.

See also the recent paper proposing a Vegaviidae with four taxa, spanning the K-Pg boundary.
totally not British, b-baka!

I don't even really like this song that much but the title is pretty relatable sometimes, I guess.
