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 09 - The Rise of the Mammals. This episode is the first of several to concentrate on mammals. The platypus and the echidna are the only mammals that lay eggs (in much the same manner of reptiles),
and it is from such animals that others in the group evolved. Since mammals have warm blood and most have dense fur, they can hunt at night when temperatures drop. It is for this reason that they became more successful than
their reptile ancestors, who needed to heat themselves externally.
