For nearly four billion years, the continents of Earth were lifeless. But during the Ordovician period, the planet’s oceans became the stage for one of the most profound upheavals in life’s history. In the shallow seas that blanketed the young world, primitive organisms diversified explosively, giving rise to a bewildering array of strange and wondrous creatures.
Ancient Oceans takes viewers on an immersive journey beneath those primordial waves, tracing the origins and evolution of early sea life across hundreds of millions of years. Through vivid reconstructions and expert insights from paleontologists and geologists, the series reveals how the earliest ecosystems emerged, adapted, and competed in a world dominated by water and governed by dramatic environmental shifts. As continents drifted, sea levels rose and fell, and climates changed, life in the oceans both thrived and struggled laying the groundwork for future chapters in Earth’s story.
