Sensory systems: Geckos shake up our understanding of vertebrate audition

A newly discovered auditory pathway in geckos processes low-frequency vibrations using the saccule, an inner ear organ previously thought to serve only vestibular functions in amniotes. These findings challenge our understanding of hearing evolution and suggest greater conservation of auditory function across vertebrates.
