 You know, this project is based on following the first humans who walked out of Africa, right? So, of course, I'm kind of looking down at my feet as I'm walking through one of our origin sites, the Rift Valley of northeastern Africa. And after talking to experts, they said the place is just littered with millions of stone tools. And what are those stone tools? They're kitchen utensils. They're choppers, they're meat cleavers, they're cutters, they're scrapers. So the African Rift, where we were born, was basically a giant cutting board, a kitchen.
