Birds That Don't Exist: Niche Pre‐Emption as a Constraint on Morphological Evolution in the Passeroidea
We use topological data analysis to reveal a persistent morphological gap in a major group of songbirds (superfamily Passeroidea). The gap remained unoccupied for millions of years, even though nearb...

The "birds that don't exist" paper is out in Ecology Letters! 🍻 We found a viable body form that has never evolved in a big clade of songbirds, and tested a series of hypotheses to figure out why.
