In the latest episode of the SciShow List Show, host Michael Aranda offers up a variety of interesting facts how different animals and insects visually process the world around them.

Eyes have been around for at least half a billion years, first appearing in the fossil record during what’s known as the Cambrian Explosion when all kinds of different animals like trilobite, starfish …came onto the scene. It’s thought that eyes have independently evolved at least 50 different times which makes sense. Even a simple eye is a useful tool giving you the evolutionary advantage over the sightless species around you.
