What are the characteristics of handicraft design in ancient America compared with other ancient civilizations?

Generally speaking, compared with other ancient civilizations, the handicraft design in ancient America has the following characteristics:

First of all, the special geographical location and unique cultural development model have caused the unique features and characteristics of the ancient American handicraft design field. Due to the isolated and closed geographical environment, the development of ancient American civilization has distinct uniqueness. On the one hand, the ancestors of ancient America created brilliant civilizations and made great contributions to the whole history of human civilization. In agriculture, American Indians first began to grow corn, peanuts, potatoes, sunflowers, tobacco and other crops; In medicine, they first discovered cinchona, foxglove, Pogostemon and other drugs; In terms of astronomical calendar, their solar calendar is even better than the European calendar of the same period; In terms of architecture, the roads, pyramids and temples they built are huge and magnificent, and their scale, quality, technology and artistry are incredible; In addition, their outstanding skills in metal casting, pottery making and textile can be compared with almost any ancient nation. On the other hand, however, the development of ancient American culture is quite incomplete. They don't know how to cast iron, can't use pottery wheels, can't make wheeled carriages, don't know how to use arch coupon structures in buildings, and even besides raising alpacas, there is no animal husbandry here. The abnormal development of culture is bound to leave a deep impression in the field of handicraft design, which is manifested in the high development of pottery, metalworking and textile design, as well as the thinness and blanks of many other handicraft design categories closely related to daily life. It is this imbalance that makes us marvel at the high achievements of some kinds of handicraft design in ancient America, and at the same time feel puzzled and sorry for some aspects of naivety and backwardness. Of course, the reason why people are confused and unfamiliar with the development of ancient American handicraft design today is also related to the tragic history of the United States full of blood and fire since the end of 15. While the colonists from Europe slaughtered Native Americans madly, they also spared no effort to destroy the once glorious civilization of ancient America, and a large number of historical relics and artistic treasures were burned. The original works of ancient American design that we can see today are all survivors of this cultural catastrophe. This situation, to a certain extent, has influenced us to make a complete and scientific judgment on the overall picture and real situation of ancient American handicraft design.
