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 04 - The Swarming Hordes. This episode details the relationship between flowers and insects. There are some one million classified species of insect, and two or three times as many that are yet to be labelled.
Around 300 million years ago, plants began to enlist insects to help with their reproduction, and they did so with flowers. Although the magnolia, for instance, contains male and female cells, pollination from another plant is preferable
as it ensures greater variation and thus evolution. Flowers advertise themselves by either scent or display.
