Travel the world on foot and you learn a lot. I'm Marco Wurman.

The journey of this explorer.

It's a storytelling journey that's following the footsteps of the ancestors across the world in the pathways of the first human dispersal out of Africa.

With his own two feet, he's covered nearly two dozen countries.

I've walked about 15,000 miles out of Africa through the Middle East, Central Asia, South Asia, and now China.

He's met fascinating people.

He had learned to make exact duplicates of Pizza Hut pizzas here in the

middle of India. On a path as old as humanity, I crossed the border into Jordan, came to this ancient

city that was tucked into a sandstone canyon. Paul Salopec's walk tracing the path of human migration

all this hour on the world.

I'm Carolyn Beeler.

And I'm Marco Wurman.

If you're feeling a little lethargic after yesterday, lace up your walking shoes and hit the road with us for our special roaming edition of the show.

With us, journalist Paul Salopac.

He has Pulitzer Prizes to his name for reporting from Africa and on the Human Genome Diversity Project.

In 2013, he applied his lifetime of reporting experience to what would grow into the biggest story of his career.

A project he calls the Out of Eden Walk. It's a storytelling journey, right, that's following the footsteps of the ancestors across the world

in the pathways of the first human dispersal out of Africa back in the Stone Age, right,

kind of rediscovering the world with the ghostly ancestors, you know, kind of leading the way.

How I do this is by hooking up with local people who know the landscape, who know not just

navigational details, but also know the culture who know the landscape, who know not just navigational details,

but also know the culture, know the history, the folkways, and I get passed from hand to hand.
