When Penguins Went From The Sky To The Sea

The video explores the evolution of penguins from their earliest known ancestor, Waimanu, to modern species. It discusses the adaptations that make penguins efficient underwater predators, the evolutionary trade-offs between flying and diving, and the history of giant penguins. The video also examines the ecological interactions between penguins and marine mammals, highlighting the impact of major extinctions on penguin evolution.
