Digest: An emerging model system for understanding ecomorphological convergence

Abstract

Morales et al. test predictions of adaptive radiation theory and phenotypic convergence in Myotis bats using genomic target capture and a morphological dataset that represents 80% of the species described for this genus. The authors demonstrate that ecomorphological convergence has occurred multiple times throughout the history of Myotis, despite finding no diversification rate shifts associated with phenotypic adaptation. These patterns provide evidence that parallel adaptive radiations can be the result of nonadaptive lineage diversification followed by repetitive exploitation of ecomorphological solutions.
