Life on Earth
Life on Earth: A Natural History by David Attenborough is a BBC nature documentary series about a study of the evolution of life on the planet. The series consists of thirteen episodes and begins with David Attenborough's opening narration: "There are some four million different kinds of animals and plants in the world.
Four million different solutions to the problems of staying alive. This is the story of how a few of them came to be as they are." The first episode is devoted to illustrating the diversity and origins of life on Earth. And then through the next 12 episodes the series looks at the evolution of living creatures including
the sea-living creatures, insects, amphibians, reptiles, birds, mammals, primates and humans.
Episode 01 - The Infinite Variety. This episode begins in the South American rainforest, whose rich variety of life forms is used to illustrate the sheer number of different species.
Since many are dependent on others for food or means of reproduction, David Attenborough argues that they couldn't all have appeared at once. He sets out to discover which came first,
and the reasons for such diversity. He starts by explaining the theories of Charles Darwin and the process of natural selection, using the giant tortoises of the Galapagos Islands (where Darwin voyaged on HMS Beagle) as an example.
