If we go into the Andes, near modern-day Peru, we have the Chavin culture, right over there. As you can see, a lot of these cultures, at least the ones that I'm putting here, and this is just a sample, I'm sampling some of North America, some around Mesoamerica, and some in the Andes. And then you can even go further back, and you can go to the Coral civilization. And what's really interesting about the Coral civilization is some archaeologists call this the first civilization. And it's unclear whether they farmed grains and cereals that we often associate with civilizations. They used their surplus crops to have a more specialized labor force. But they were a maritime culture.
