Ornament, armament, or toolkit? Modelling how population size drives the evolution of birdsong, a functional cultural trait

2021-04-30

Abstract excerpt

Oscine songbirds have been an important study system for social learning, particularly because their learned songs provide an analog for human languages and music. Here we propose a different analogy; from an evolutionary perspective, could a bird’s song be more like an arrowhead than an aria? We modify a model of human tool evolution to accommodate cultural evolution of birdsong: each song learner chooses the mos...
