The Trials of Life watch online

The Trials of Life: A Natural History of Behaviour is a BBC nature documentary series written and presented by David Attenborough, first transmitted in the United Kingdom from 3 October 1990.

A study in animal behaviour, it was the third in a trilogy of major series (beginning with Life on Earth) that took a broad overview of nature, rather than the more specialised surveys of Attenborough's later productions. Each of the twelve 50-minute episodes features a different aspect of the journey through life, from birth to adulthood and continuation of the species through reproduction.

The series was produced by the BBC Natural History Unit in conjunction with the Australian Broadcasting Corporation and Turner Broadcasting System. The executive producer was Peter Jones and the music was composed by George Fenton.

Part of Attenborough's Life series, it was preceded by The Living Planet (1984) and followed by Life in the Freezer (1993).
