Life on Earth began surprisingly early, but stayed simple for billions of years.
In short: This video introduces a four-part series exploring the history of life on Earth. It highlights how life emerged early in the planet's timeline, yet remained dominated by simple organisms for the first two billion years of its existence.
While life may have originated early in Earth's history, the initial two billion years were characterized by a lack of complexity. During this vast stretch of time, the planet was inhabited exclusively by simple life forms, despite several significant biological developments occurring.
This overview serves as the first installment in a comprehensive four-part series examining the long-term progression of life on our planet.
