Listen to this fish story

Human Ears Evolved from Ancient Fish Gills
Humans and other land animals have special bones in their ears that are crucial to hearing. Ancient fish used similar structures to breathe underwater.

Scientists had thought the evolutionary change occurred after animals had established themselves on land, but a new look at an old fossil suggests ear development was set into motion before any creatures crawled out of the water.

Later in my dive back down to Atlantis I'll test how much I can breathe through my ears.
