Can we logically assume that the Maya would borrow a lotus motif or a serpent column from southeast Asia, but not the dome or true arch? Is it likely that sailors from Asia or Oceania succeeded in introducing useful plants but not sails or boats that could tack against the wind? If transoceanic diffusion is to be considered seriously, should there be no evidence for even a few practical seagoing inventions shared between the Old World and the New? Surely this would be more acceptable to the Americanists than forcing the assumption of transoceanic diffusion upon the presence of cultivated plants of secondary importance, or theological concepts expressed so vaguely as to be subject to alternative interpretations. 11 THE INDIAN IN AGRICULTURE _Corn, which is the staff of life._ —EDWARD WINSLOW, _Good Newes from New England_, (1624) Inventions—Some New, Some Old Let us forget, for the moment, white conquerors like Alexander and white gods like Quetzalcoatl. Let us suppose that the Indian actually invented his own culture. This does not mean that we throw diffusion out of the window; for the Indian may have invented things in the Old World and brought them to the New—which is one kind of diffusion. On the other hand, he may have invented in the Americas the same things that other peoples were inventing—before or after him—in Eurasia. That, of course, is independent invention. There is a third possibility: that the Indian invented things in the New World which none of the peoples of the Old World ever invented. If he could do this, then it is obvious that he could invent some things which other people had also invented. The Indians ability to invent uniquely is a far stronger argument for independent invention than the theory of “psychic unity.” It is also an argument for early man, if the things invented can be dated far back in time. Nordenskiöld and others list a number of inventions that are unique to the New World.[1] Among them are the hammock; the tube of diagonally woven fibers which enabled the lowland Indians of South America to squeeze the poison from the manioc and produce wholesome tapioca; the ventilating and cooling system of the kivas (the subterranean religious chambers of the pueblos); the Peruvian whistling jar; the cigar, cigarette, tobacco pipe, cigar holder; the quipu (a set of knotted strings for counting); the enema syringe; the hollow rubber ball; elastic rings; the toboggan; the Maya calendar and hieroglyphs; and possibly the snowshoe. If the list is not very impressive, consider how few unique inventions the Old World could muster in the same kind of stone age.
