حیات در سیاره ما

قسمت 1 : 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.

قسمت 2 : 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.

قسمت 3 : 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.

قسمت 4 : 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.

قسمت 5 : 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.

Emerging from the dinosaurs' shadows, mammals went from underdogs to global power, with game-changing adaptations that would conquer land, air and sea.

قسمت 8 : 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?
