There may have been 4–5 million people in Amazonia at the time of European contact. These people cultivated or managed at least 138 plant species in 1492. Many of these crop genetic resources were human artifacts that required human intervention for their maintenance, i.e., they were in an advanced state of domestication. Consequently, there was a relationship between the decline of Amazonian Amerindian populations and the loss of their crop genetic heritage after contact. This relationship was… CONTINUE READING
