The origin of humans is in Botswana. Researchers used DNA to find out where we came from. They said all our roots are in northern Botswana. Humans were there 200,000 years ago. They lived there for 70,000 years and then moved across Africa. They then moved to Europe and Asia. Professor Vanessa Hayes, from the University of Sydney, said: "We've known for a long time that modern humans originated in Africa roughly 200,000 years ago."
The researchers said we come from an area called Okavango. People there had water, hunting and farmland. Scientists looked at DNA from 200 people who live near there today. The people had a lot of DNA called L0. Professor Hayes explained why L0 is important. She said: "Every time a new migration occurs, that migration event is recorded in our [L0 and] DNA as a time-stamp.... Everyone walking around today...comes from this region."
