EO Wilson – Of Ants and Men is a two-hour film about the life and extraordinary scientific odyssey of one of America’s greatest living thinkers, E.O Wilson. It is an exciting journey of ideas, but also an endearing portrait of a remarkable man; often dubbed “a Darwin for the modern day.” Starting with his unusual childhood in Alabama, it chronicles the lifelong love for the natural world that led him to Harvard and the studies that would establish him as the world’s foremost authority on ants.
But that was just the beginning. His discovery of ant pheromones in the 1960’s led him to start thinking about systems of communication in nature on a much grander scale. He was one of the first to start thinking about ecosystems, still a revolutionary concept at the time, and the ways different species fitted together inside them. His book, “Island Biogeography” and the word “biodiversity,” which he coined in the 1980’s, have since become the cornerstones of conservation biology, something he is very proud of.
This would have been enough for most scientific careers, but there was so much more to come.

Take a risky dive into an underwater cave in Mexico to discover the 13,000-year-old skeleton of a prehistoric teenager. Follow forensic clues that reveal intimate details of her life and death, and how her people first ventured into North America.

Where did we come from? What makes us human? An explosion of recent discoveries sheds light on these questions, and NOVA's comprehensive, three-part special, "Becoming Human," examines what the latest scientific research reveals about our hominid relatives.
Part 1, "First Steps," examines the factors that caused us to split from the other great apes. The program explores the fossil of "Selam," also known as "Lucy's Child." Paleoanthropologist Zeray Alemseged spent five years carefully excavating the sandstone-embedded fossil. NOVA's cameras are there to capture the unveiling of the face, spine, and shoulder blades of this 3.3 million-year-old fossil child. And NOVA takes viewers "inside the skull" to show how our ancestors' brains had begun to change from those of the apes.
Why did leaps in human evolution take place? "First Steps" explores a provocative "big idea" that sharp swings of climate were a key factor.
