Another built a replica of a mole rat burrow in a horizontally mounted wheel, so that as the mole rat ran along the tunnel, the wheel could be spun to keep the animal adjacent to the camera. These adaptations can be truly extraordinary: fish that walk or lay eggs on leaves in mid-air; snakes that fly; flightless birds that graze like deer; and bears that grow hair on the soles of their feet. However, it had claws on its wings and there is only one species alive today that does so: the hoatzin, whose chicks possess them for about a week or so. Coral reefs contain the greatest variety of species, many of which are conspicuously coloured to ward off predators or attract mates. The dinosaurs' growth was limited by the strength of their bones but the whales only rely on water to support their weight, and so have been able to grow into the world's largest animals.

There are some one million classified species of insect, and two or three times as many that are yet to be labelled.

And yet, despite facing literally every conceivable setback that living organisms could encounter, life has been extinguished and picked itself up to evolve again. No one can say just how many species of animals there are in these greenhouse-humid dimly lit jungles. Their acute sense of vision led to them standing erect to spot predators, leaving their hands free to bear weapons. In 1999 viewers of Channel 4 voting for the 100 Greatest TV Moments placed the gorilla sequence at number 12—ranking it ahead of Queen Elizabeth II's coronation and the wedding of Charles and Diana. Join Life on Earth to appreciate the all of it's beauties and the importance of us humans urgently making a different to protect such precious creatures on our planet.

Initially, the films we made tried to document the lives of particular animals showing how each found its food, defended itself and courted, and the ways in which it fitted into the community of animals and plants around it. Overall a very good quality service from this seller and I would not hesitate to recommend this seller. Life on Earth: A Natural History by David Attenborough is a British television natural history series made by the BBC in association with Warner Bros. Maybe fish had developed muscular fins and crawled on to land to become amphibians; maybe amphibians in their turn had developed watertight skins and become reptiles; maybe, even, some ape-like creatures had stood upright and become the ancestors of man.The final episode deals with the evolution of the most widespread and dominant species on Earth: humans.
