Did you know that you and I are only 1% human — we've 90 trillion cells which don't belong to us. Yes we are more bacteria than human.
David Attenborough has a passion for birds' eggs. These remarkable structures nurture new life, protecting it from the outside world at the same time as allowing it to breathe. They are strong enough to withstand the full weight of an incubating parent and weak enough to allow a chick to break free. But how is an egg made? Why are they the shape they are? And perhaps most importantly, why lay an egg at all? Piece by piece, from creation to hatching, David reveals the wonder behind these miracles of nature.
Plants are able to communicate with each other in ways we are only now beginning to understand. Some plants can differentiate between roots of their "family" and roots of other kinds of plants when they touch underground. See how plants "talk" to each other and find out what they talk about!
Remote islands offer sanctuary for some of the planet's strangest and rarest creatures. The rare pygmy three-toed sloth enjoys a peaceful existence on an idyllic Caribbean island, while nesting albatross thrive in predator-free isolation. But island life always comes at a cost. On the Galapagos Islands, young marine iguana must escape an onslaught of deadly racer snakes the moment they hatch from the sand. On the sub-Antarctic island of Zavodovski, life gets more extreme still. Every day, one and a half million penguins risk being battered against the rocks by fierce waves as they try to get on and off the island.

We flail, we swat, we sweat. We spray, cover up, and hide. But still the tiny, fearsome mosquito penetrates our best defenses. ZAPPED: the buzz about mosquitoes is the story of our ongoing struggle to conquer a little insect that is both delicate and deadly. As the program reveals, this beautiful and versatile blood-sucker has always managed to stay one step ahead of us. As tortured as we are Zapped uncovers, in exquisite detail, how the mosquito goes about its handiwork. It's really only the females that are the problem – they need our blood to incubate their eggs. And, out of more than 3500 species, only 200 or so transmit disease.
