The Life of Mammals is a nature documentary series written and presented by David Attenborough, first transmitted in the United Kingdom from 20 November 2002.

Each of the ten episodes looks at one (or several closely related) mammal groups and discusses the different facets of their day-to-day existence and their evolutionary origins.

The mammals are such a widespread, varied and successful group of animals that Attenborough had previously devoted no fewer than five episodes of Life on Earth to them.

To capture footage for the first time of skunks foraging in a cave of bats, extra protective measures had to be taken for the crew, as it was a very hostile environment.

The air was full of ammonia, the main occupants urinated copiously from above, and other inhabitants included flesh-eating maggots and a rattlesnake.

For a sequence featuring grizzly bears at close quarters, the camera team were accompanied by Buck Wilde, an ursine specialist.

The difficulties involved were first actually finding an ideal tree, and then, having settled on one, watching out for passing snakes and primates en-route to the top.

In the final program of this series, "Food for Thought", he took the opportunity to put the case explicitly for finding ways to deal with overpopulation.

"Warm-bloodedness is one of the key factors that have enabled mammals to conquer the Earth, and to develop the most complex bodies in the animal kingdom.

The Dutch version of the DVD produced by Evangelische Omroep removed all references to (amongst others) evolution, fossils, and continental drift.
