Big congratulations to Jeff Bezos, who rode torturous working conditions for his employees, an avalanche of monopolization that put small business into the dirt, and a rocket ship that looks like a penis into 10 minutes in low-Earth orbit.

Abstract The status signalling hypothesis aims to explain within-species variation in ornamentation by suggesting that some ornaments signal dominance status. Here, we use multilevel meta-analytic models to challenge the textbook example of this hypothesis, the black bib of male house sparrows (Passer domesticus). We conducted a systematic review, and obtained primary data from published and unpublished studies to test whether dominance rank is positively associated with bib size across studies.
