Broadcast (2007) In a story blooming with beauty and scientific mystery, this program explores the incredible truth that lies behind the ravishing flowers we so love to behold: that humans could not have existed or evolved without them. "First Flower" probes the controversial discovery of Archaefructus, a Chinese fossil scientists believe is the earliest evidence of a flower yet found on Earth.

Broadcast (1989) Could a pterodactyl as large as a light aircraft have flown? Did millipedes once grow to six feet long? How did insects become preserved in amber for over 50 million years? All these questions and more are answered through the study of fossils. In his journeys to the most famous fossil sites in the world, David Attenborough discovers a pre-historic world teeming with life and full of enticing clues as to how life evolved. They reveal how dinosaurs hunted, lived in groups and cared for their young.

Broadcast (2002) When we think of animals, we think of movement. Surprisingly, the diverse and graceful ballet of animal movement may have started with cnidarians (pronounced "ny-DAIR-ee-ans), a group that includes corals, sea anemones, sea pens and jellyfish. All of these animals, with few exceptions, have nerves and muscles. Because cnidarians are the simplest animals to possess this complexity, their direct ancestors were very likely the first animals to bundle the power of nerves and muscles together, enabling them to move and exhibit discernible behavior.

Broadcast (2002) Behind the beautiful shapes and colors of seashells is the story of how a group of animals called molluscs evolved in order to survive. The wide variety of molluscs includes clams, oysters, snails, mussels, squid, and octopus. The word mollusc comes from Latin meaning "soft," a good description of the group's fleshy bodies. Of course, in an ocean filled with predators, a soft body is easily eaten.

Broadcast (1998) Most of the dry land on Earth sits no more than a few hundred metres above sea level. But in some places mountain belts rise to heights of several kilometres.These regions are often prone to devastating earth tremors. How are mountains formed and what is the connection with earthquakes? The answer may lie in the fluid-like properties of the Earth's outer layers. According to a new theory, mountains may flow up or down when continents collide. In the process they affect the circulation of the planet's atmosphere and change the climate. (

Charles Darwin's theories radically changed the way we view the evolution of man; other top discoveries in evolution include the Burgess Shale fossils that provide a snapshot of ancient life andthe KT Asteroid which caused the demise of the dinosaurs. (

Broadcast (2003) Understanding of humans' earliest past often comes from studying fossils. They tell us much of what we know about the people who lived before us. There is one thing fossils cannot tell us; at what point did we stop living day-to-day and start to think symbolically, to represent ideas about our environment and how we could change it? At a dig in South Africa the discovery of a small piece of ochre pigment, 70,000 years old, has raised some very interesting questions. (
