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?
