The environment does not determine the character of human culture; it merely sets the outer limits. - Peter Farb

All routinized religions today (including the Native American Church, Islam, Judaism, and Christianity) are successful descendents of what originated as messianic movements—that is, the vision of a new way of life for a culture under extreme stress.

The Hopewell fused elements of the Adena, the Archaic, and other Woodland patterns of life. Thus, it cannot technically be identified as a culture. ...Rather, the Hopewell people were an amalgam of many societies whose customs varied greatly, but who were bound together by... a cult of the dead and a trade bond... a network of trade linked widely separated areas of the continent.

Within a century or so after the discovery of America, more than fifty new foods had been carried back to the Old World, including maize, turkey, white potato, pumpkin, squash, the so-called Jerusalem artichoke, avocado, chocolate, and several kinds of beans. (Potatoes and maize now rank second and third in total tonnage of the world's crops, behind rice but ahead of what is probably man's oldest cultivated grain, wheat.) The European has turned for relief to drugs and pharmaceuticals the Indians discovered: quinine, ephedrine, novocaine, curare, ipecac, and witch hazel.
