The chiefdoms of the northern Andes, northern Venezuela, and the Antilles had an estimated total population of 1,900,000, with densities ranging from 6.6 to 1.1 persons per square mile (2.5 to 0.4 persons per square kilometre).
The southern Andes was inhabited by the Araucanians, whose combined population was possibly 1,131,000, with a density range of 0.38 to seven persons per square mile.
It was a period of thousands of years’ duration, however, toward the end of which some knowledge of plant domestication reached the Peruvian coast.
