Let’s check out next the Andean Civilizations: https://en.wikipedia.org/wiki/Andean_civilizations
“The Andean civilizations were complex societies of many cultures and peoples mainly developed in the river valleys of the coastal deserts of Peru. They stretched from the Andes of Ecuador southward down the Andes to northern Argentina and Chile. Archaeologists believe that Andean civilizations first developed on the narrow coastal plain of the Pacific Ocean. The Caral or Norte Chico civilization of Peru is the oldest civilization in the Americas, dating back to 3200 BCE.
Despite severe environmental challenges, the Andean civilizations domesticated a wide variety of crops, some of which became of worldwide importance. The Andean civilizations were also noteworthy for monumental architecture, textile weaving, and many unique characteristics of the societies they created.
Less than a century prior to the arrival of the Spanish conquerors, the Incas, already established in coastal of the Pacific Ocean, united most of the Andean cultures into one single state which encompasses all of what is usually called Andean civilization. The Muisca of Colombia and the Timoto Cuica of Venezuela remained outside the Inca orbit. The Inca Empire was a patchwork of languages, cultures and peoples.
Spanish rule ended or transformed many elements of the Andean civilizations, notably influencing religion and architecture.”
“Uniqueness
Andean civilization was one of five civilizations in the world deemed by scholars to be "pristine", that is indigenous and not derived from other civilizations.[2] Due to its isolation from other civilizations, the indigenous people of the Andes had to come up with their own, often unique solutions to environmental and societal challenges.
Andean civilization lacked several characteristics distinguishing it from the pristine civilizations in the Old World and from the Mesoamerican cultures. First, and perhaps most important, Andean civilizations did not have a written language. Instead, their societies used the quipu, a system of knotted and colored strings, to convey information. Few quipus survive and they have never been fully deciphered. Scholars differ on whether the knotted cords of the quipu were able only to record numerical data or could also be used for narrative communication, a true system of writing.[4] The use of the quipu dates back at least to the Wari Empire (600–1000 CE) and possibly to the much earlier civilization of Norte Chico of the third millennium BCE.
Andean civilizations also lacked wheeled vehicles and draft animals. People on land traveled only by foot and the transport of goods was only by humans or llama, pack animals which could carry loads of up to one-fourth of their weight, a maximum of 45 kilograms (99 lb).[6] Llamas were not big or strong enough to be used for plowing or as riding animals for adults.
Moreover, Andean civilizations faced severe environmental challenges. The earliest civilizations were on the hyper-arid desert coast of Peru. Agriculture was possible only with irrigation in valleys crossed by rivers coming from the high Andes, plus in a few fog oases called lomas. In the Andes, agriculture was limited by thin soils, cold climate, low or seasonal precipitation, and a scarcity of flat land. Freezing temperatures may occur in every month of the year at altitudes of more than 3,000 metres (9,800 ft), the homeland of many of the highland Andean civilizations.
Finally, the Andean civilizations lacked money. Copper axe-monies (also called "naipes")[8] and Spondylus shells[9] functioned as mediums of exchange in some areas, especially coastal Ecuador, but most of the Andes area had economies organized on reciprocity and redistribution rather than money and markets. These characteristics were especially notable during the Inca Empire but originated in much earlier times.”
