Mitosis

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.

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.

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.

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?

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.

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.

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.

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.

Take a fascinating journey inside the bizarre world of a living human being with this compelling documentary from National Geographic, where microscopic cameras and other state-of-the-art technologies reveal perspectives that will blow your mind. Tracking the body of a female from infancy to old age, viewers will observe the digestion of a meal, the development of the cardiac system and other mesmerizing aspects of the body's inner workings.

A documentary that explores the natural world of the sea, from the single-celled organism to more complex forms of life, OCEAN ORIGINS was originally filmed in the IMAX large format, which adds a crispness and clarity to the images. This documentary film seeks to examine the process of evolution by looking at the many creatures of the sea that can illustrate the way multi-cellular life emerged over the course of four billion years. OCEAN ORIGINS is a creative film that uses fascinating documentary footage to look at scientific theories and principles in an interesting manner

With cinematic storytelling, a moving musical score, computer animation, and 4D ultrasound images, this documentary accompanies a new human life from conception to birth, poetically describing developmental milestones and the human experience of living in a womb.

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.

When Harvard PhD student Jennifer Brea is struck down at 28 by a fever that leaves her bedridden, doctors tell her it’s "all in her head." Determined to live, she sets out on a virtual journey to document her story—and four other families' stories—fighting a disease medicine forgot.

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.

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.

Bacteria, viruses, but also fungi, algae, pollen, and even insects: micro-organisms thrive and circulate constantly in our sky. How can so many living beings find their way into the air and circulate? How do they survive? And what influence do they have on our lives and the living world? Biodiversity, health, climate: it is only recently that scientists have begun to understand how this discreet aerial "plankton" affects our lives and our ecosystem. But despite their many virtues, some of these micro-organisms are now threatened by human activities. With the help of experts and 3D models, this scientific investigation plunges us into the heart of a still mysterious world, and reveals the diversity and fragility of the air we breathe.

Explore an extraordinary region where water and land life intermingle six months out of the year.

Since the law of August 2, 2021, on bioethics, French women between the ages of 29 and 37 have the right to collect and freeze their eggs, free of charge, without medical reason, regardless of their marital status. From this simple law, and thus from this right, emerges a complex and fascinating reality.

Advanced technology, groundbreaking scientific discoveries about the beginnings of life, and computer animation all combine to detail how multiple siblings develop in the womb as the filmmakers at National Geographic explore the fetal growth of twins, triplets, and quadruplets. Detailed pictures of these different groupings in various stages of fetal development bring the earliest stages of life to the screen as never before.

The forest is like an organism, ancient and full of mechanisms. Its plants need water and are temperature-dependent. Nevertheless, it survives in a wide variety of locations around the world. How does it manage to adapt to even the most adverse conditions?
