It turns out that potatoes are wild species and contain a lot of toxins (solanine). Eating it raw will kill people. However, it seems that all the ancient Indians were possessed by the Shennong family. After trying to improve again and again at the risk of life, no matter how many setbacks, it is difficult to erase the ancient Indians' love for potatoes.

Before potatoes entered the United States, Indians mainly lived by collecting berries. These berries include blueberries, blackberries and cranberries. They are not only sweet and sour, but also rich in various nutrients. The domestication of potato was completed by Indian ancestors in South America 8000 years ago. This is one of the most important contributions of Indians to world civilization.

Indians also domesticated other foods, such as corn, sweet potatoes, cassava, peanuts and tomatoes. For South American residents, the Andes are cold and barren, and potatoes are more important than corn.

A brief introduction to the origin of South American Indians

According to archaeological records, South American civilization began in BC 10000, when the first immigrants from North America and Central America arrived. They settled in Tierra del Fuego, Argentina, southern Chile, the south-central plain of the Grand Canyon and the central Andes. Their group is based on blood relationship, and their class is determined by gender and age. These nomadic groups were later replaced by highly agricultural clubs. Agricultural society is located in Arawak coast and inland forest areas of Brazil and Antilles.

Because they have abundant food, they can maintain a large and stable social unit. Other ethnic groups who have settled in the Caribbean coast and the northern Andes, based on military and religious ceremonies and supported by agricultural technology, have emerged more complex forms of social organization.

The indigenous civilization of South America took root and sprouted in the middle of the Andes around 2300 BC, and then made rapid progress, which lasted for thousands of years in agriculture and science and technology. Around the year 1000, the kingdoms of Chimu and Tiwanaku appeared, and later the Inca Empire.
