(2/6) Guinea #baboons live in a multi-level society with male philopatry. We compared male grunt similarity within and between parties and gangs, while controlling for genetic relatedness #AnimBehav2021
(3/6) Grunts within social levels …were more similar than across levels – but the effects were *very* small. Similarly, males within social levels were more highly related than between social levels … #AnimBehav2021
(4/6) … but that did not explain acoustic similarity: no difference in similarity between unrelated and highly related males. „Auditory priming” could account for within-group acoustic similarity, i.e. vocal convergence #AnimBehav2021
(5/6) We stress the importance of distinguishing between different mechanisms that support vocal learning. Vocal convergence in baboons, chimps, marmosets is not the same thing as word learning in humans. #AnimBehav2021 Paper here
