From Life in the Water to Life on Land
Kenya’s freshwater fish face extreme changes as seasonal waters recede, but the African lungfish has adaptations that allow it to survive in shallow, oxygen-poor pools. This clip from BBC’s Evolution episode "The Elephant" follows the lungfish’s ability to breathe air and use its fleshy fins to move, offering a glimpse into the evolutionary transition from life in water to life on land.
The video traces this transition through ancient fish such as Eusthenopteron, whose features foreshadowed the limbs and lungs of early land vertebrates. These adaptations established the tetrapod body plan — the four-limbed blueprint shared by elephants, humans, birds, whales, and countless other animals, despite the remarkable ways evolution has modified it for different environments.
