<b>Evolutionary rate variation in passerine birds’ song complexity and its consequences for speciation</b>

<p dir="ltr">Bird song complexity has attracted scientific interest for centuries, mainly because song complexity is a sexually selected signal, and its divergence will produce reproductive isolation and speciation.
Description
Yet comparative tests have been hindered by inconsistent definitions of song complexity. We tested the former hypothesis that lineages exploring the song phenotypic space more broadly increase their speciation rate.
Using recordings from 4,088 passerine species, we quantified an explicit dimension of complexity through the irregularity of the song. We used FABRIC to reconstruct directional change and historical variation in evolutionary variance, then tested whether cumulative pathwise evolvability covaried with speciation using Quantitative State Speciation and Extinction model (QuaSSE), ES-sim and parametric-bootstrap analyses. Directional shifts were heterogeneous but biased towards increasing complexity, whereas inferred evolvability shifts were almost exclusively increases.

The best-supported QuaSSE model described a positive sigmoidal association: estimated speciation remained low at low historical evolvability, rose sharply across an intermediate range and approached an upper plateau. These results identify heterogeneous evolution of a reproducibly defined song property and link its historical capacity for change to uneven passerine diversification. The plateaus are compatible with limits imposed by weak signal divergence at low evolvability and saturation of diversification at high evolvability.</p>
