The Evolution of the Eye
Vision transformed the way animals interacted with their surroundings, turning survival into a game of seeing, sensing, and responding. This clip from BBC’s Evolution episode "The Dolphin" travels back to the Cambrian Period, when complex eyes began appearing in many forms, including the prominent eyes of trilobites, and explores how the rise of vision may have driven an evolutionary arms race between predators and prey.
Rare Cambrian fossils also preserve evidence of neural tissue and even brain structures, offering clues to the connection between increasingly sophisticated eyes and increasingly complex brains. From wide-ranging compound eyes to giant camera-like eyes, the video traces the remarkable variety of ways animals have evolved to process the visual world around them.
