The Fish that Strolls on the Sea Floor

The video explores the evolution of walking from fish to land vertebrates, focusing on the little skate's unique locomotion. It discusses two types of vertebrate movement: ambulatory and undulatory locomotion. The little skate's punting behavior provides insights into the evolution of walking, suggesting that fish may have had the neural tools for walking long before moving onto land. Genetic studies reveal similarities between skate and land animal motor neurons, indicating a shared evolutionary path. The research has implications for understanding vertebrate evolution and developing walking robots.
