Understanding the Evolution and Functionality of Eyes

Michael Stevens discusses five key facts about the eye, highlighting its role in technological advancements such as cancer-detecting cameras and drones. He explains that eyes evolved independently across species to aid survival, with humans developing stereoscopic vision for hunting. Humans can see 10 million colors, aiding mate selection, but this pales in comparison to animals like birds and mantis shrimp. Animals like goats have unique eye adaptations to protect against predators.
