From dinosaurs to mammoths, when our ancient ancestors encountered the fossil bones of extinct prehistoric creatures, what did they think they were? Just like us, ancient peoples were fascinated by the giant bones they found in the ground. Historian Tom Holland goes on a journey of discovery to explore the fascinating ways in which our ancestors sought to explain the remains of dinosaurs and other giant prehistoric creatures, and how bones and fossils have shaped and affected human culture.
In Classical Greece, petrified bones were exhibited in temples as the remains of a long-lost race of colossal heroes. Chinese tales of dragons may well have had their origins in the great fossil beds of the Gobi desert. In the Middle Ages, Christians believed that mysterious bones found in rock were the remains of giants drowned in Noah's Flood.
Tom encounters a medieval sculpture that is the first known reconstruction of a monster from a fossil, and learns about the Native Americans stories, told for generations, which contained clues that led bone hunters to some of the greatest dinosaur finds of the nineteenth century.

An Ice Age relic found in a mysterious cave is evidence of prehistoric humans' connection to the supernatural. Using cutting-edge tech, experts investigate this 40,000-year-old treasure to reveal why it was made and the long-lost myths it represents.
In the summer of 1939, a team of explorers unearthed hundred of mammoth ivory fragments within a cave in Germany. Due to the start of World War II, the explorers were forced to abandon their findings, and the fragments laid forgotten in a museum. Decades later, as archeologists began piecing the fragments together, an extraordinary artifact emerged -- a figure with both animal and human features, now known as the 'Lion man.'

David Attenborough joins an archaeological dig uncovering Britain’s biggest mammoth discovery in almost 20 years. In 2017, in a gravel quarry near Swindon, two amateur fossil hunters found an extraordinary cache of Ice Age mammoth remains and a stone hand-axe made by a Neanderthal. Professor Ben Garrod joins the team at DigVentures during the excavation as they try to discover why the mammoths were here and how they died. Could the Neanderthals have killed these Ice Age giants?

'It's alive!' Since Dr. Frankenstein spoke those famous words, we've been alternately enthralled and terrified by the idea of creating life in the lab. Now, a revolution in genetic engineering and thrilling innovations in synthetic biology are bringing that dream—or nightmare, as the case may be—closer to reality. New tools allow researchers to use cells to create their own DNA and edit it into existing genomes with more ease and less cost than ever before.
Along with renewed hopes for treating some genetic diseases, there's serious talk of using the newest technologies to bring long-extinct animals back from the dead – like the team hoping to resurrect the woolly mammoth. Science fiction is quickly becoming science fact. Another daring genetic experiment to bioengineer animals could prevent Lyme disease. But the power to make life comes with deep ethical questions. What are the potential rewards—and dangers—of tinkering with nature? This films explores the benefits and the burden of risk surrounding the controversial new technology.

'Deliver Us from Drought' - Over the past years, Texas has experienced the worst drought in its recorded history. 97% of the scientific community agrees that human activity has contributed to extreme weather patterns around the world. But many Texans--legislators, community leaders and citizens--don't attribute their drought to humans, and have taken few if any initiatives to limit the state's CO2 emissions, currently the highest in the country. "The Resource Curse" - As humanity's appetite for energy grows exponentially, the extraction industry scrambles to the most remote regions on Earth. In the undeveloped Melanesian country of Papua New Guinea, America's Exxon Mobil has staked its claim to a $19 billion liquid natural-gas project. While some see Exxon's mammoth presence as the catalyst that will usher the underdeveloped country into the 21st Century, others predict the initiative could plunge its people into civil war.

A mammoth Tsunami strikes the eastern seaboard. It would be a disaster of epic proportions. Some scientists believe this catastrophe could happen one day, but how? This episode shows the Atlantic island of La Palma has collapsed several times in mega-landslides. Another could trigger a tsunami with enough power to cross the Atlantic Ocean and decimate the US East Coast.
