where did the natives of south america come from
Indigenous peoples of South America It is believed that the first human populations of South America either arrived from Asia into North America via the Bering Land Bridge, and migrated southwards or alternatively from Polynesia across the Pacific.[12][13][14] The earliest generally accepted archaeological evidence for human habitation in South America dates to 14,000 years ago, the Monte Verde site in Southern Chile.[15] The descendents of these first inhabitants would become the indigenous populations of South America.
Geography of South America South America became attached to North America only recently (geologically speaking) with the formation of the Isthmus of Panama some 3 million years ago, which resulted in the Great American Interchange. The Andes, likewise a comparatively young and seismically restless mountain range, runs down the western edge of the continent; the land to the east of the northern Andes is largely tropical rain forest, the vast Amazon River basin. The continent also contains drier regions such as eastern Patagonia and the extremely arid Atacama desert.
