Abstract

Mysticetes (baleen whales) include the largest animals on Earth and are renowned for their songs and long-distance communication. Even so, the scope and origins of their hearing abilities remain poorly understood. Recent work on their sister clade, the toothed whales (odontocetes), has revealed notably convergent trends in the evolution of their inner ear. Here, we test whether the same applies to baleen whales via SURFACE, a phylogenetic method that fits Ornstein-Uhlenbeck models with stepwise Akaike Information Criterion to identify instances of convergent evolution. We identify a single convergent regime, including minke (Balaenoptera acutorostrata) and Bryde’s (Balaenoptera edeni) whales, which, however, is not statistically significant. We discuss potential reasons for the overall absence of convergence and suggest improvements for future work.
