>>507286384Did you know there were tiered levels of civilization in Peru?
It was based on the type of crops/live stock that can be kept on each mountaintop.
The animals could be grazed at the highest elevation but nothing could be grown.
The lower areas were designated with a crop depending on it's ability to grow at each spot of elevation.
Also, all of their dwellings were made of stone and you can still look them up today, although supposedly geographically isolated they share extremely similar creation myths to everyone else.
