What strange forces saved one isolated section along the Upper Mississippi River from the repeated crushing and scouring effects of glaciers during the last two million years? And what pre-Ice Age throwbacks survived here in this unique geologic refuge that holds more Native American effigy mounds, petroglyph caves, strange geological features, and rare species than anywhere in the Midwest? These questions and more are answered in this captivating new documentary. A team of scientists embarks on a journey of exploration to expose both the science and threats behind three unique features of the zone - rare plants and animals, odd geological phenomenon, and striking remnants of a Native American pilgrimage like no other.
A documentary of insect life in meadows and ponds, using incredible close-ups, slow motion, and time-lapse photography. It includes bees collecting nectar, ladybugs eating mites, snails mating, spiders wrapping their catch, a scarab beetle relentlessly pushing its ball of dung uphill, endless lines of caterpillars, an underwater spider creating an air bubble to live in, and a mosquito hatching.
The biggest tech revolution of the 21st century isn’t digital, it’s biological. A breakthrough called CRISPR gives us unprecedented control over the basic building blocks of life. It opens the door to curing disease, reshaping the biosphere, and designing our own children. This documentary is a provocative exploration of CRISPR’s far-reaching implications, through the eyes of the scientists who discovered it, the families it’s affecting, and the genetic engineers who are testing its limits.
Travel alongside the astronauts as they deploy and repair the Hubble Space Telescope, soar above Venus and Mars, and find proof of new planets and the possibility of other life forming around distant stars.
From the unique vantage point of 200 miles above Earth's surface, we see how natural forces - volcanoes, earthquakes and hurricanes - affect our world, and how a powerful new force - humankind - has begun to alter the face of the planet. From Amazon rain forests to Serengeti grasslands, Blue Planet inspires a new appreciation of life on Earth, our only home.
Darwin's great insight – that life has evolved over millions of years by natural selection – has been the cornerstone of all David Attenborough’s natural history series. In this documentary, he takes us on a deeply personal journey which reflects his own life and the way he came to understand Darwin’s theory.
Many geneticists and archaeologists have long surmised that human life began in Africa. Dr. Spencer Wells, one of a group of scientists studying the origin of human life, offers evidence and theories to support such a thesis in this PBS special. He claims that Africa was populated by only a few thousand people that some deserted their homeland in a conquest that has resulted in global domination.
Featuring Michael Pollan and based on his best-selling book, this special takes viewers on an exploration of the human relationship with the plant world — seen from the plants' point of view. Narrated by Frances McDormand, the program shows how four familiar species — the apple, the tulip, marijuana and the potato — evolved to satisfy our yearnings for sweetness, beauty, intoxication.
Documentary footage from various sources, set to music. Showing the whole of human life, from birth to death and beyond.
A breathtaking adventure across five continents and through time to reveal nature's most vital secret. Watch a flying fox gorge itself on a midnight snack of figs. Climb into the prickly jaws of insect-eating plants. Witness a mantis disguised as a flower petal lure its prey to doom.
In The Womb is a 2005 National Geographic Channel documentary that focus on studying and showing the development of the embryo in the uterus. The show makes extensive use of Computer-generated imagery to recreate the real stages of the process.
In 1858 Charles Darwin struggles to publish one of the most controversial scientific theories ever conceived, while he and his wife Emma confront family tragedy.
The film is filled with fun facts that show how cats make good pets, yet in other ways are wild and untamable.
THE BRAIN is an astonishing voyage of discovery into our last biological frontier. Although today s computers can make calculations in one-100th of a second and technology can transport us outside the bonds of Earth, only now are we beginning to understand the most complex machine in the universe. Using simple analogies, real-life case studies, and state-of-the-art CGI, this special shows how the brain works, explains the frequent battle between instinct and reason, and unravels the mysteries of memory and decision-making. It takes us inside the mind of a soldier under fire to see how decisions are made in extreme situations, examines how an autistic person like Rain Man develops remarkable skills, and takes on the age-old question of what makes one person good and another evil. Research is rushing forward. We’ve learned more about the workings of the brain in the last five years than in the previous one hundred.
David Attenborough takes us on a guided tour through the secret world of plants, to see things no unaided eye could witness. Each episode in this six-part series focuses on one of the critical stages through which every plant must pass if it is to survive:- travelling, growing, and flowering; struggling with one another; creating alliances with other organisms both plant and animal; and evolving complex ways of surviving in the earth's most ferociously hostile environments.
Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?
An African narrator tells the story of earth history, the birth of the universe and evolution of life. Beautiful imagery makes this movie documentary complete.
