Earth’s history is a tale of resilience, transformation, and survival. In this episode of Cosmos in a Pod, host Amitesh takes you on a journey through the planet’s most dramatic eras—from the asteroid impact that ended the reign of dinosaurs to the icy grip of the Ice Ages and the dawn of human civilization. Explore how Earth recovered, evolved, and thrived through apocalyptic changes.

Episode Highlights:

• The Cataclysmic Asteroid Impact: Discover how a 10-kilometer-wide asteroid wiped out 75% of life, plunging Earth into a global winter and paving the way for mammals to rise.
• Earth’s Recovery in the Paleocene: Learn how the planet rebounded with lush forests and thriving ecosystems, only to face warming from tectonic and greenhouse gas shifts.
• The Cooling Planet: Explore the events that brought Earth into cooler climates, from the uplift of the Himalayas to the formation of Antarctic glaciers.
• The Ice Age Giants: Meet megafauna like woolly mammoths and saber-toothed cats, and uncover how humans adapted to icy landscapes.
• The Dawn of Civilization: Understand how the retreat of glaciers in the Holocene Epoch created fertile lands, giving rise to agriculture and human innovation.
• The Anthropocene Era: Examine the age of humans and the impact of climate change on Earth’s future.

FAQs Answered:

• What caused Earth’s Ice Age? A combination of tectonic activity, ocean current changes, and Milankovitch Cycles drove glacial advances.
• Why did Ice Age megafauna go extinct? Likely due to a mix of climate change and overhunting by humans.
• Are we living through another mass extinction? Yes, the sixth mass extinction is underway, driven by human-induced habitat destruction and climate change.

Join us as we journey through Earth’s incredible history and uncover lessons from its past that could help shape its future.
