Paul Salopek, a 50-year old American journalist, is going for a very long walk. He is on his way to walk 21,000 miles (34,000 km), which is expected to take him 7 years and about 30,000,000 footsteps. Salopek isn’t doing this for the exercise – he is actually retracing some rather historical steps of mankind.
It is believed that we humans showed up on Earth around 200,000 years ago in the continent of Africa. We hung out there for thousands of years, and then some of us moved on and explored other continents. Scientists believe that humans first moved out of Africa around 60,000 years ago. Salopek is trying to retrace a route our ancestors might have taken thousands of years ago as they explored our planet. His journey started in Ethiopia and will end at the southern tip of Chile in 2020. The project is called “Out of Eden”, and you can follow Salopek here.
Did you know? The oldest bones of the human species that we have found were in Ethiopia. The bones are of two humans who have been named Omo I and Omo II. They lived about 195,000 years ago.
