A 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 programmes 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 David 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, David Attenborough presented State of the Planet (2000) and narrated The Blue Planet (2001).
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. Nevertheless, there was much that remained untold and behaviour that was not hitherto filmed. The Life of Mammals was intended to be his definitive account of the subject.
Attenborough took on the series at the suggestion of the BBC Natural History Unit. The naturalist's wife, Jane, had died in 1997, midway through the making of The Life of Birds, which had caused its postponement. However, Attenborough had been grateful for the fact that there was still work to be done to ensure its completion. Similarly, he was glad of another opportunity to keep himself occupied:
"The Life of Birds was transmitted in the autumn of 1998, and was sufficiently well received for the Unit to ask me if I would like to tackle another similar series about another group of animals. How about mammals? I was in my mid-seventies but I decided I would rather do that than sit at home by myself."[1]
Despite his age, Attenborough travelled just as extensively as in all his previous productions, with each episode leapfrogging to a multitude of locations around the world.
The filming, as ever, provided many challenges. 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. When a bear was too inquisitive he was able to command it to turn away simply by raising his hands. However, a cameraman confessed that at the time, he was sure there would come a moment when the animal would just continue towards them regardless.[2]
To get themselves up into the canopy of a tropical rainforest the crew used a catapult to fire a fishing line 100 metres into the uppermost branches. This was then attached to a rope and pulley counterbalance system. 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.[2]
Big cats that hunt nocturnally, such as lions, leopards and tigers, had never been extensively filmed doing so before. But the latest infrared technology revealed behaviour that had previously been guessed at from evidence discovered the next day.[2]
The series was among the first to benefit from the features of digital television. After each episode's transmission on BBC One, terrestrial viewers were shown a ten-minute featurette on an aspect of its making. Those with digital equipment had the option of switching to an interactive quiz, hosted by Attenborough.
In his previous natural history series, Attenborough had been reticent about describing man's impact on the natural environment (unless it was relevant to the content, as in the last episode of The Living Planet or The First Eden). However, since State of the Planet, the presenter had become more publicly outspoken on the subject. In the final programme 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. In this series, we will travel the world to discover just how varied and how astonishing mammals are."

This programme discusses insectivores. Shrews are descendants of the earliest mammals, which were scurrying creatures that had a diet of insects. Their warm blood enabled them to hunt at night while dinosaurs slept; they nurtured their young and gave them milk. When the dinosaurs died out some 65 million years ago, the surviving mammals' inherent features meant that they could proliferate. These shrew-like creatures evolved: the elephant shrew is shown, alongside its prepared pathway of getaway routes; while others adapted further into species of mole, including the golden mole. The increased relative size of armadillos came about because they broadened their diet. Other animals grew larger owing to more of their favoured nutrition being available: these include the giant anteater and the pangolin. However, Attenborough hails the evolution of the bat – a winged mammalian insect catcher that can navigate using echolocation – as being "magical". The European brown long-eared bat switches off its echolocation and then uses its keen sense of hearing to detect an insect's location through its movements. He ascends 3 kilometres into the night sky over Texas to investigate why there should be so many bats at such a height. It transpires that this is also heights to which moths from the Tropics climb up as they migrate. Whereas the bats in Texas are forced to migrate in winter, Attenborough visits a cave in Canada where they stay all year round and go into deepest hibernation when the cold weather arrives. In New Zealand, bats seem to have reverted to the hunting techniques of their ancestors, and are shown tackling a weta on the ground. | |||

The next instalment looks at herbivorous mammals. The sloth is a leaf-eater, but it has compensated for the lack of nutriment in its diet by doing less (its reactions are a quarter the speed of a human's). This does not apply to all herbivores, which rely on bacteria in their stomachs to digest the leaves' cellulose. Plants can be poisonous, but Brazilian tapirs – the largest inhabitant of the South American rainforest – deal with them by eating a little of each species and then supplementing it with kaolin. The pika collects and stores plants to survive through the winter. In East Africa, via infrared cameras, Attenborough observes a herd of elephants squeezing into a pitch black cave and gouging the walls with their tusks to mine salt for their diet. Grazing animals, such as caribou and wildebeest, must migrate at the onset of winter and make long journeys to find new pastures. Despite its spiny fortification, the acacia is favoured by antelope, elephants and giraffes, which all have adaptations to reach its leaves. Smaller grazers are always at risk from carnivores: so they have developed the means to detect and evade them, and do so more often than may be supposed. A herd of buffalo are shown defending one of their number by charging the lions attacking it. However, the horns of antelope are primarily used for fighting each other to determine rank within their group and to maintain a breeding ground. Topi are shown doing so to the point where they are so exhausted that they easily succumb to a pack of hyenas. | |||

|
This programme is devoted to carnivorous mammals. Attenborough starts in the English countryside, where, besides humans farming sheep, a stoat chases and catches a rabbit. Meat is one of the most energy-rich foods there is, and there are several groups that eat it exclusively. Among the most prolific to do so are cats and dogs. Canine adaptations are varied, and are illustrated by the differences between fennecs and Arctic foxes. Along the coast of the Namib, a Brown Hyena family is shown hunting for fur seals and scent marking their territory. In the Amazon, lacking in large land mammals, the rare South American Bush Dog is shown hunting for aquatic prey. Meanwhile, the biggest concentration of meat occurs on the plains of Africa, and African hunting dogs are shown capturing a wildebeest with efficient teamwork. However, the largest wild canid is the wolf, and Attenborough successfully communicates with a pack of them in North America before they embark on an exhausting hunt for elk. Back in Africa, infrared cameras are used to examine the nocturnal activities of lions, which bring down a zebra. During the day, a solitary cheetah – the fastest animal on four legs – swiftly overtakes an impala and despatches it. One of the most adaptable of the big cats is the leopard, and infrared technology is again used to spot one of them as it searches an Indian village for domestic goats. As it does so, it comes dangerously close to the hut where Attenborough sits with his observation equipment. Finally, Attenborough visits the frozen North to witness the animal kingdom's most powerful predator, the Siberian tiger, albeit one that is held in captivity. | |||
| 6 | "The Opportunists" | 8 January 2003 (2003-01-08) | |

The next instalment deals with those mammals that are omnivorous. Attenborough goes to the Atlanta Zoo to see the giant panda. He contrasts its restrictive diet of bamboo with the less selective forms of nutrition favoured by other species. The raccoon is among the most successful: its sensitive hands and inquisitive nature have enabled it to become extremely adaptable. To the other extreme, one of the scarcest omnivores is the babirusa, a kind of pig found in Indonesia. A good sense of smell is vital for such creatures and wild boars have become expert foragers. Foxes have gained a reputation for killing more chickens than they need to: in fact they demonstrate foresight by burying surplus food to eat later. Skunks visit a cave of bats and cross a carpet of guano to seek out the young that fall from the ceiling. The most formidable opportunists are grizzly bears, and Attenborough observes them fishing for migrating salmon in Alaska. Their feeding habits in the lead up to hibernation are discussed in detail. The replacement of natural habitats by modern cities and the extravagance of their human occupants have provided a rich source of sustenance for many. Raccoons, bears and foxes have all become well adapted to an urban lifestyle. However, in this regard, it is the brown rat that has become most abundant. Finally, Attenborough points out that it is the opportunistic traits of humans that have enabled them to dominate the world. | |||

The next programme surveys arboreal mammals. Attenborough's introduction takes place in the close company of meerkats. They work as a team, and one will always act as a lookout. For this it climbs to the highest point nearby, which in this instance proves to be Attenborough's shoulder. Up in the canopy of the tropical rainforest, there is a greater variety of food than anywhere else in the natural world, so it is unsurprising that many animals exist there. Sloths and coatis exemplify the skills needed to move around in such a habitat. Especially suited to ascending tree trunks are sun bears and tamanduas, the latter possessing a prehensile tail, something it has in common with the woolly monkey. The flying squirrel can leap a distance of 15 metres by virtue of the fur membrane between its wrist and ankle. A five million-strong colony of fruit bats is also shown, and little impact is made on their numbers by predatory eagles and crocodiles. Infrared cameras are again employed to study nocturnal lorises and lesser bushbabies. Their ancestral relatives reached the island of Madagascar, where they diversified and are known as lemurs. They are particularly adept at jumping, and their technique is analysed. They are hunted by the fossa, an arboreal carnivore, which is a match for them athletically. In the forests of Southeast Asia can be found the "supreme tree-traveller", the fastest flightless inhabitants of the canopy in the world: gibbons. | |||

The penultimate instalment focuses on monkeys. Together with apes (which includes humans), monkeys are part of the most social group of mammals. Their habits are rooted in relationships with others of their kind and a natural intelligence and inquisitiveness. Capuchins display all these qualities as they search for food. The differing face colours of the saki denote seniority within its group. The only nocturnal monkeys are douroucoulis and being active at night enables them to share the food resources of others in the same area. Pygmy marmosets, the smallest monkeys in the world, are captured feeding at the tops of trees and gnawing away on tree trunks to feast on the gum inside. Different tamarin species are shown co-operating to alert each other to the presence of a common predator, a tayra. Monkeys have good colour vision, and howler monkeys use it to select non-toxic leaves to eat. Attenborough travels through the African jungle with an alliance of species: several types of monkey and even mongooses combine to watch out for danger. They have a different alarm call for each enemy and Attenborough demonstrates this by placing a stuffed leopard nearby. In Sri Lanka, the naturalist also spends time with a troop of toque macaques – one of the most studied groups of monkeys in the world. It has been discovered that the creatures are born into a class system, in which position brings privileges. When the world's climate changed 10 million years ago, some monkeys ventured into open grassland, and they are illustrated by some of the most resourceful: baboons and geladas. | |||

"Three and a half million years separate the individual who left these footprints in the sands of Africa from the one who left them on the moon. A mere blink in the eye of evolution. Using his burgeoning intelligence, this most successful of all mammals has exploited the environment to produce food for an ever-increasing population. In spite of disasters when civilisations have over-reached themselves, that process has continued, indeed accelerated, even today. Now mankind is looking for food, not just on this planet but on others. Perhaps the time has now come to put that process into reverse. Instead of controlling the environment for the benefit of the population, perhaps it's time we control the population to allow the survival of the environment."
— David Attenborough, in closing
