Sir David Attenborough's landmark natural history programmes have educated and inspired us for more than seven decades.
From hanging out with primates to early climate warnings, here's a selection of his trailblazing programmes - to mark his 100th birthday - and where to watch them in the UK.
Life on Earth was Attenborough's ambitious, globe-spanning attempt to tell the story of life in a way that had never been attempted before, "from the first primitive cells to the plants and animals that now live around us".
It established Attenborough as the foremost TV naturalist, as well as an iconic British cultural figure.
It was "absolutely groundbreaking for the time", according to Dr Jean-Baptiste Gouyon, author of BBC Wildlife Documentaries in the Age of Attenborough.
