The origin of humans is in Botswana. Researchers said all our roots are in northern Botswana. Humans were there 200,000 years ago. They moved across Africa and into Europe and Asia. A professor said: "We've known for a long time that modern humans originated in Africa roughly 200,000 years ago."
Researchers said we come from an area called Okavango. They looked at DNA from people who live near there today. The people had a lot of DNA called L0. The professor said every time people moved, that event was recorded in our L0. It was a time-stamp. She said everyone walking around today is from this region.
