Evolution of Vision

The evolution of vision began with simple light-sensitive cells in early organisms, allowing them to detect changes in light and dark. Over time, these cells became more organized, forming primitive eyes that could identify the direction of light. As species evolved, more complex eyes developed, enabling better image formation, focusing, and color detection. This progression improved survival by helping organisms find food, avoid predators, and navigate their environment. Today, many animals have highly sophisticated eyes, demonstrating how visual systems evolved gradually through natural selection to meet diverse ecological needs.
