David uses the latest 3D technology to explore a world beyond the confines of our human senses. He begins with the secret world of plant movement and uses sinister carnivorous plants to show just how active plants can be. Bladderwort utricularia is a pond-dweller that is among the fastest known, its traps snapping shut in less than a millisecond. As the seasons change, David demonstrates how plants operate on a different time scale to us; how they modify their lives according to the time of year. We discover insects' hidden links with plants, both as pests and ...
Our body is a true time machine. It is a mirror of the history of the living world.

He would go to the most logical, the most efficient, the most rational; and when you look closely, this is not always what characterizes us.
Reveals the unknown side of a world-famous river that has shaped a whole continent. Over a period of two years, the Science Vision team traveled 90,000 kilometers and spent 481 days on location, returning with over 400 hours of material. Only two hours will be included in the finished film.
In this episode, Chris reveals how the world's most spectacular grasslands flourish, despite being short of one essential nutrient - nitrogen. As it turns out, the secret lies with the animals. There are the white rhinos of Kenya that create nitrogen hotspots by trimming and fertilising the grass. They are drawn to these particular points by communal toilets or 'fecal facebooks', where they meet and greet each other. In the whistling acacia grasslands of Kenya, Chris reveals the amazing relationships between termites, geckos, ants, monkeys and giraffes that make these places so rich in wildlife
Two billion years ago, a giant meteorite crashed into southern Africa's interior plateau, forming a six-mile-deep crater. Today, the site of this cataclysmic event is the Vredefort Dome--a dazzling and rich ecosystem of unique plant and animal life.
