This series tells the story of mankind, in this episode starting billions of years ago with the early days of the earth's existence, when there was not yet life on our planet.

This video on the history of life on Earth looks at the emergence of reptiles and amphibians on land, and the different types of dinosaurs that roamed the land before continental drift occurred.

The dinosaurs die out and the Earth is populated with small mammals and apes, who slowly adapt to their surroundings over millions of years.

Now the apes are slowly climbing down from the trees and starting to walk upright. What are the names of the next species and what characterizes them? Join us and witness this stage of our journey through the history of mankind.

Life is hard for Homo erectus, whose biggest challenge is to find enough food. At some point, one thing becomes very clear: It's better to hunt as a team!
