The Life of Mammals

It is a documentary on the study of the evolution and habits of the various mammal species. It was the fourth of Attenborough's specialised surveys following his major trilogy that began with Life on Earth. 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. All the programs are of 50 minutes duration except the last, which extends to 59 minutes.

The series was produced by the BBC Natural History Unit in conjunction with the Discovery Channel. The executive producer was Mike Salisbury and the music was composed by Dan Jones and Ben Salisbury. It was later shown on the Discovery Channel.

Part of Attenborough's Life series, it was preceded by The Life of Birds (1998) and followed by Life in the Undergrowth (2005). However, in between the former and this series, Attenborough presented State of the Planet (2000) and narrated The Blue Planet (2001).
