Lungfish and salamanders can hear, despite not having an outer ear or tympanic middle ear. These early terrestrial vertebrates were probably also able to hear 300 million years ago, as shown in a new study by Danish researchers.
The lungfish ear is a good model for the ears of the first terrestrial vertebrates. A new study shows that they are capable of detecting airborne sound despite not having a tympanic middle ear.
