How did the Indians met by Columbus differ from the Indians of Central America?

The Indians of South America had a number of distinctive features from the North American inhabitants. Tribal unions actively made contact with visiting Europeans. Before the arrival of the Portuguese, their activities were mainly hunting and gathering. The prerequisites for the formation of a state were just emerging for them. They lived in tribal unions and had already begun to grow crops and animals in limited numbers. The Indians had access to the gold reserves of the mainland and the rest of the mining sites.
