Evolution of hearing

After Genesis, a number of surviving species were capable of several basic senses, such as touch, sight, and taste. However, it wasn't until much later that species evolved with the ability to hear.

Early hearing

The ear of V. aborealus features an ear drum with attached nerves.

Dracuanguilacerta audioacrus was the earliest species capable of detecting sound, evolving from D. aquacanthus on March 23rd, 2019. While their exact means of detecting sound is unknown, it plays a role in their mating ritual. To attract females, male audioacrus stomp on the ground, the sound of which is picked up by females up to 1.5 miles away.

The first species with an explicit ear appeared more recently with Varanusuchus aborealus, evolving from V. colonisuchus on May 6th, 2019. Its primitive ears are only able to detect the presence of vibrations, which they use to enhance their awareness of nearby prey and predators. Their ears are highly simplistic, consisting of an ear drum and an attached nerve to pick up the vibrations. It is unlikely that they are able to differentiate between prey and predators in this way.

Since then, hearing has evolved on several occasions in multiple groups, ranging from the dracilids to several kinds of wyverns.
