Physicist Jim Al-Khalili embarks on an extraordinary quest through 600 million years of evolution to reveal how the human brain — the most complex structure known in the universe — came to exist. With more than 100 billion neurons and 100 trillion connections, it surpasses even the stars of the Milky Way. Through breathtaking science and striking visuals, this documentary uncovers how nature transformed simple nerve cells into the ultimate thinking machine. From the first survival instincts of primates to the dawn of social intelligence, Jim explores how cooperation, relationships and empathy reshaped the brain and made us who we are. Working alongside his wife and leading researchers, he dives into fossil evidence, brain scans and the rise of artificial intelligence to answer one profound question: what makes the biological brain so unique — and can anything ever match it?
Deep beneath the Indian Ocean, a team of explorers embarks on a bold scientific mission to capture one of nature’s rarest survivors — the coelacanth, a fish unchanged for 400 million years. Narrated by David Attenborough, the film follows NHK’s deep-sea crew aboard the OceanX vessel as they attempt the world’s first 72-hour observation of this living fossil. Using cutting-edge submersibles, they descend into an ancient realm where time itself seems frozen. As the cameras reveal the coelacanth’s slow, graceful movements, scientists uncover vital clues about evolution’s greatest leap — the moment life crawled from sea to land. Blending adventure, technology, and breathtaking natural history, this deep-ocean odyssey illuminates how a single fish still holds the key to understanding our own beginnings.
