Life is a British nature documentary series created and produced as a co-production between the BBC Natural History Unit, Discovery Channel and Skai tv in association with The Open University. It was first broadcast as part of the BBC's Darwin Season on BBC One and BBC HD from October to December 2009 and was written and narrated by David Attenborough. The series takes a global view of the specialised strategies and extreme behaviour that living things have developed in order to survive; what Charles Darwin termed "the struggle for existence". Four years in the making, the series was shot entirely in high definition.

Life premiered on 12 October 2009 in the United Kingdom consisting of ten 50-minute episodes. The opening programme gives a general introduction to the series, a second look at plants, and the remainder are dedicated to some of the major animal groups. They aim to show common features that have contributed to the success of each group, and to document intimate and dramatic moments in the lives of selected species chosen for their charisma or their extraordinary behaviour. A ten-minute making-of feature Life on Location aired at the end of each episode, taking the total running time to 60 minutes.
