NOVA - S50E15: Ancient Earth: Humans

The story of Earth can only be told because now, 4.5 billion years into its existence, a technological and self-aware animal species roams its surface, able to study the very planet that gave rise to it. But how exactly did Earth give rise to humans? Through stunningly realistic animation, witness the cataclysmic asteroid strike that wiped out the dinosaurs, the tumultuous changing climates that allowed early primates to spread across the planet, and the geologic events that created the conditions for the evolution of an animal that walks upright on two legs. Explore the power and paradox of humanity’s profound impact on our planet, and ponder the question of how we may shape its future.
