Journey of Life (2005) BBC

Airborne

Animals crawled on to the land 500 million years ago, but it was another 100 million years before life finally became airborne. Just four kinds of animals achieved the miracle of flight. Insects led the way, but their story is still shrouded in mystery.

Steve Leonard takes a 4 billion year journey from the first spark of life to the conquering of a planet. In a journey from sea, to land, to sky, life has evolved remarkable solutions to the challenge of survival. This series visits the crucial moments in life's journey to dominate the earth. 'Seas of Life' reveals that the basic blueprint of a brain, backbone, two legs and two arms was created in the ocean. 'Land Grab' follows life as it changes from a fish to a human; and 'Airborne' illustrates the four evolutions of flight. In 'Living Together', relationships - predatory, competitive and co-operative - are revealed.

And in 'Human Life', the differences between us and chimps, phenomenally similar creatures, are examined. The latest graphic techniques recreate evolution before your very eyes, providing viewers with a spectacular representation of how life came to be.
