Not by signalling alone: Music's mosaicism undermines the search for a proper function.
Article in The Behavioral and brain sciences, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Mehr et al. seek to explain music's evolution in terms of a unitary proper function - signalling cooperative intent - which they cash out in two guises, coalition signalling and (allo)parental attention signalling. Although we recognize the role signalling almost certainly played in the evolution of music, we reject "ultimate" causal explanations which focus on a unidirectional, narrow range of causal factors.
