For the Gaspé Peninsula in the province of Quebec and for the Pyrenees Mountains there is a variety that matures in two months; for Colombia there is one that requires ten or eleven months. The height ranges from two feet to twenty; the leaves vary from eight to forty-eight; the number of stalks by a single seed, from one to twelve; the ears from three inches to three feet. Authorities used to list from five to eight basically different types of corn; the five are sweet, flour, dent, flint, and pop. “The Russians,” write P. C. Mangelsdorf and R. G. Reeves, “have already collected more than 8,000 varieties.”[17]

All the chief types of corn known today were developed by the Indians to suit the wide variety of lands and climates in which they lived. The feat seems all the more remarkable because botanists tell us that all these varieties had to be developed by keen observation and hard work from a single parent species—_Zea mays L._—and modern man has never found corn in a wild form. This amazingly varied plant, which cannot properly seed itself and will die without man’s intervention, was evolved from a plant that is now apparently extinct.
In spite of the old saw about the staff of life, a starchy grain is not the ideal food; but corn, says Sauer, is the most useful of all American starches because in addition to its ease of storage “it contains also fat and protein and is a more nearly complete food than the others.”[18]
Obviously it must have taken many long years for the Indian to develop corn from its unknown ancestor into its many and widespread varieties. One botanical authority, G. N. Collins, thinks 20,000 years would not be enough—if a gross mutation, or sudden genetic change, were ruled out.[19] Other botanists do not accept such a figure. The development of corn may have taken a good many centuries or, more likely, a few millenniums. Behind corn must lie more centuries or more millenniums during which the first agriculturists of the New World discovered how to grow other plants, because whether corn originated in Middle America, Colombia, or Paraguay—independent inventionists argue for each locality—or in all three with the Mississippi Valley thrown in, there can be no question that it came later than most of the other cultivated plants. This adds still more years to the story of the civilizing of man in the Americas. Bruman writes:
