Life On Our Planet: Season 1

Evolution, competition, mass extinction: 4 billion years of life's rules.

Uninhabitable land for eons, but predation in the seas led to thriving species before and after two mass extinctions.

Hostile land to hospitable habitat: Early species, including moss, trees, insects, and amphibians, vied for domination.

After Earth's third mass extinction, mammals' surviving ancestors ruled the super continent Pangea. But lizards soon ushered in the age of reptiles.

Varied continents fueled biodiversity and supercharged dinosaur evolution.

The dinosaurs met their end with a cataclysmic asteroid impact. Rising from the ashes, birds reinvented themselves into a dynasty 10,000 species strong.

Mammals rose from underdogs to global power, with game-changing adaptations conquering land, air, and sea after the dinosaur era.

Ice Age to human dominance, but a sixth mass extinction threat questions our ingenuity's role in our potential downfall.
