005 Earth - One Minute History

The video explores Earth's formation from stellar dust, leading to a molten proto Earth. A collision with a planetoid formed the moon, and asteroid impacts paved the way for microbial life. Oceans formed, and oxygen appeared. Supercontinents shifted, causing ice ages and greenhouses, while life evolved from algae to multicellular organisms. The Cambrian explosion marked the arrival of animals, followed by extinctions and the evolution of land plants, mammals, dinosaurs, and hominids. Earth's vast history is categorized into eons, eras, periods, and epochs.
