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.
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.
Opylování rostlin
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.

This documentary outlines the unique properties and latest studies of "Physarum Polycephalum", also known as Blob.
An award-winning feature-length creative documentary exploring the extraordinary world of the plasmodial slime mould through the eyes of the fringe scientists, mycologists and artists. In recent years this curious organism has become the focus of much research in such areas as biological-inspired design, emergence theory, unconventional computing and robot engineering.
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.
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.
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.

Documentary footage from various sources, set to music. Showing the whole of human life, from birth to death and beyond.
They have no roots, no seeds, no flowers, but mosses show immense survival capacities and can suspend their biological activity for long periods. Today, researchers are exploring the exceptional resistance of these archaic organisms. British ecologists have even resurrected a "zombie" moss that has been trapped in the permafrost for 1,500 years. Associated with decay and disliked in Europe, mosses are deified in Japan. With 25,000 species worldwide, bryophytes - their scientific name - are the seat of real ecosystems, and can develop in inhospitable landscapes, through an extravagant reproduction cycle.
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.
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?
The Atlantic Flyway, the easternmost migration path in North America, is among the most vital ecological phenomenons in the world. Join explorer Tomas Koeck as he examines several unlikely relationships along this massive migratory chain.
Le Secret de la marche
From homosexual penguins and sex-transitioning fish to pregnant male seahorses and sexually dominant female bonobos, thousands of species defy our expectations of gender and sexuality. Director Drew Denny takes the nature documentary to a whole new level in this eye-opening and entertaining expedition to the places David Attenborough overlooks, where giant duck penises and corkscrew vaginas take center stage. Debunking myths that females are “inferior” and being queer is somehow “unnatural,” Second Nature explores the 1500+ animal species that engage in same-sex sexual behavior and parenting, change sex, form matriarchies, and more.
