امروزه بیش از بیست میلیون گونه جانوری در سیاره زمین وجود دارد و گونه های بی شماری در گذشته دور از بین رفته است. در مستند «حیات در سیاره ما»، به سراغ تاریخچه چهار میلیارد ساله زمین و اوج و فرود گونه های مختلف جانوری می رویم.
بخش ۱: قوانین حیات
Evolution. Competition. Mass extinction. Three fundamental rules have driven the rise and fall of life on Earth for over four billion years.
بخش ۲: اولین مرزبان
For billions of years, land on Earth was uninhabitable. But in the seas, predation allowed species to thrive before — and after — two mass extinctions.
بخش ۳: مهاجمین سرزمین
Sprawling moss, towering trees, flying insects, limbed amphibians: Early species vied for domination as the land went from hostile to hospitable.
بخش ۴: با خونسردی
After Earth's third mass extinction, mammals' surviving ancestors ruled the supercontinent Pangea. But lizards soon ushered in the age of reptiles.
بخش ۵: در سایه غول پیکرها
The formation of continents with varied environments allowed for an explosion of biodiversity — and turbo-charged the evolution of mighty dinosaurs.
بخش ۶: برون از خاکسترها
The dinosaurs met their end with a cataclysmic asteroid impact. Rising from the ashes, birds reinvented themselves into a dynasty 10,000 species strong.
بخش ۷: به ارث بردن زمین
Emerging from the dinosaurs' shadows, mammals went from underdogs to global power, with game-changing adaptations that would conquer land, air and sea.
بخش ۸: عصر یخ و آتش
As the Ice Age thawed, humans rose above the rest. But the possibility of a sixth mass extinction now looms: Has our ingenuity caused our downfall?
