The seven-part series, in which each episode focuses on one continent, premiered on BBC One on 27 October 2019 and is narrated and presented by naturalist Sir David Attenborough.

We will see how life developed on each continent, giving rise to the extraordinary and wonderful diversity that we see today.

Walruses gather in huge numbers in the frozen north, only to risk falling to their deaths after climbing sea cliffs to escape polar bears.

This is a world of the rarely seen, from the yeti-like golden snub-nosed monkey in the mountain forests of China to the most bizarre predator in the baking Lut desert in Iran, the spider-tailed horned viper, which camouflages itself against the rocks, then tricks migrating birds into going after its specialised tail.

Above Gibraltar, Europe's only non-human primate, the Barbary macaque lives a life of kidnapping and high drama, whilst in Vienna churchyard-dwelling European hamsters feast on flowers and candle wax left at graves.
