A new study published in Proceedings of the Royal Society B provides the most comprehensive comparative assessment of bat hearing capacity to date and highlights the evolutionary pressures acting on their sensory perception. Scientists from the Museum für Naturkunde Berlin studied bat hearing in both high and low frequency ranges used for echolocation and social communication and demonstrated that hearing sensitivity is equally good at both ranges. Moreover, a phylogenetic comparative analysis showed that changes in hearing sensitivity evolved in response to frequency changes of both echolocation and social calls.
