Unique Contributions from Comparative Auditory Research,r a specific question? This is the central aim of comparative research. The classic comparative approach involves studying animals with different but carefully chosen phylogenetic backgrounds and thereby deducing principles that are either basic, and thus shared by common descent, or specializations

The correlations of their anatomy to specific aspects of their auditory physiology (e.g., reversed tonotopic organization) have helped greatly in the elucidation of the evolution of

However, within the last 20 years, the audiograms of several fish and frog species have been shown to encompass ultrasonic (US) frequencies. Moreover, these animals have been shown to respond behaviorally to US playbacks. Although the evolution of US detection in these species is still an

These accessory structures for the inner ear increased the sensitivity to airborne sound, the frequency range of hearing, and the directionality of the ear.

However, this internal anatomy is rarely visible in fossils. Historically,

The large paleognathous birds are characterized by low-frequency vocalizations whereas the smaller paleognathous birds vocalize at higher frequencies with hearing in those that have been tested matched to their vocalizations. Data from the emu suggest that the evolution of avian aud
