American paleontologist Pete Larson and his team discovered the largest and most complete Tyrannosaurus rex ever found (nicknamed 'Sue') while digging in the badlands of South Dakota. However the skeleton was seized from Larson by the federal government, followed by a ten-year-long battle with the FBI, the National Park Service, the Bureau of Indian Affairs, and Maurice Williams, on whose property the bones were discovered. Pete Larson also spent 18 months in prison." After the film aired, The Society of Vertebrate Paleontology, a society of professional academic paleontologists, issued a statement of full support for legally protecting fossils on public land and criticized Dinosaur 13 for implying that government regulations impede paleontological science

The magnificent ancient city of pyramids at Caral in Peru is a thousand years older than the earliest known civilisation in the Americas and, at 2,627 BC, is as old as the pyramids of Egypt. Many now believe it is the fabled missing link of archaeology - a 'mother city'. If so, then these extraordinary findings could finally answer one of the great questions of archaeology: why did humans become civilised?" For over a century, archaeologists have been searching for what they call a mother city. Civilisation began in only six areas of the world: Egypt, Mesopotamia, India, China, Peru and Central America. In each of these regions people moved from small family units to build cities of thousands of people. They crossed the historic divide, one of the great moments in human history. Why? To find the answer archaeologists needed to find a mother city - the first stage of city-building. Caral, is so much older than anything else in South America that it is a clear candidate to be the mother city. It also is in pristine condition. Nothing has been built on it at all. Instead laid out before the world is an elaborate complex of pyramids, temples, an amphitheatre and ordinary houses. Scientists developed a number of theories. Some said it was because of the development of trade, others that it was irrigation. Some even today believe it was all because of aliens. Gradually an uneasy consensus emerged. The key force common to all civilisations was warfare. Crucially, there is not the faintest trace of warfare at Caral; no battlements, no weapons, no mutilated bodies. Instead, Ruth's findings suggest it was a gentle society, built on commerce and pleasure. In one of the pyramids they uncovered beautiful flutes made from condor and pelican bones. They have also found evidence of a culture that took drugs and perhaps aphrodisiacs. Most stunning of all, they have found the remains of a baby, lovingly wrapped and buried with a precious necklace made of stone beads.

Richard Dawkins explores what science can tell us about death. It's a journey that takes him from Hindu funeral pyres in India to genetics labs in New York.Dawkins brings together the latest neuroscience, evolutionary and genetic theory to examine why we crave life after death, why we evolved to age and how the human genome is something like real immortality - traits inherited from our distant ancestors that we pass on to future generations.

Anthropologist Wade Davis and river advocate Robert F. Kennedy Jr journey down the Colorado River on a two-week expedition to highlight water conservation issues. Traveling by rafts, kayaks and wooden dories, they are accompanied by their daughters and guided by Shana Watahomigie, a Native American National Park ranger. Filmed with a 350-pound 3D camera, it involved the cooperation of three Indian nations, the National Park Service, film sponsor Teva’s team of kayakers and more than a dozen experienced river guides. The film explores America's drought and freshwater shortages, the impact on the river of damming, and human water supply needs. Grand Canyon Adventure: River at Risk was directed by Greg MacGillivray and narrated by Robert Redford.

An unconventional biography about an Indian Swami who brought yoga and meditation to the West in the 1920s. This feature documentary explores the life and teachings of Paramahansa Yogananda, who authored the spiritual classic Autobiography of a Yogi, which has sold millions of copies worldwide and is a go-to book for seekers, philosophers and yoga enthusiasts today. It was the only book that Steve Jobs had on his iPad, and he arranged to give away 800 copies of it to the dignitaries who attended his memorial service. It was also a point of entry into Eastern mysticism for George Harrison, Russell Simmons and countless yogis. By personalizing his own quest for enlightenment and sharing his struggles along the path, Yogananda made ancient teachings accessible to a modern audience, attracting many followers and ultimately helping millions of seekers today to turn their attention inwards, bucking the temptations of the material world in pursuit of self-realization.
