In lowland South America, tropical rain forest prevails over an area of some 2,320,00 square miles, including most of the Amazon basin and extending northward over the Guianas to the mouth of Orinoco. Generally speaking, it is the dominant vegetation below 4,000 feet in elevation, where annual average temperature variation does not exceed 5 degrees F., where rain falls on 130 or more days of the year, and where relative humidity normally exceeds 80 percent. Small enclaves of savanna appear where the soil is too porous to retain moisture during the dry season, but these are unimportant because they offer no special opportunities for human exploitation. In spite of its vast extent, the lowland tropical forest ecosystem constitutes a distinctive and remarkably homogeneous environment because of its long geological history, its uniform climate, and its equatorial location. Since these inorganic characteristics establish the boundaries within which biological and cultural adaptation take place, the story must begin with them. ~ Page 7
