Excerpt from Evolution, 1928, Vol. 2: A Journal of Nature Some Fundamentalist Versions James Usher, Archbishop of Armagh, set the date of creation in the year 4004 B.C. Dr. John Lightfoot, ViceChancellor of Cambridge University, "improved" this dating by fixing the week of creation for October 18th to 24th, so that Sunday, the 25th, became the first day of hard earned rest. But later scholars, of equal "authority," have placed the date variously at 4710 B.C. and 5872 B.C. So, after all, the doctors of divinity disagree and we may, without offense, consider Some Scientific Versions In a rear storeroom of the American Museum of Natural History in New York, I was one day privileged to examine a collection of banded clays carefully preserved with glycerine in long metal pans. From them, Dr. Chester A. Reeds and other scientists were reconstructing the history of the New Jersey, New York and New England areas at the close of the Great Ice Age, long before the coming of the white man. They already had a complete year by year record covering thousands of years, indicating a date for the melting away of the ice sheet perhaps more than ten thousand years ago, but so far not definitely connected with modern dates. One of them, Dr. E. Antevs, was, however, busily gathering samples of clay from Canada for that very purpose. He was trying to fix definite dates for the various stages of melting and retreat of the ice sheet which once covered nearly all Canada and much of the northern United States. His hopes of success rested upon a previous success elsewhere. He had assisted Baron Gerard De Geer, the Swedish geologist, in applying a new method for finding the dates of retreat of the Baltic Ice Sheet which had invaded the Scandinavian countries, Finland and parts of Germany and Russia. They had fixed dates as early as 11,600 B.C. and connected them definitely with our own calendar dates. When the long cold spell which caused the Great Ice Age came to an end, the edge of the ice sheet melted back as though retreating. Here and there along its front, pools and lakes of icy water would form. These waters of melting would be muddy with silts and gravels. During the warm summers, when melting was rapid, the swift flow of waters would carry away the finer silts, but let the coarser gravels settle in the lake bottoms. Like the Rings in a Tree When the cold of winter stopped the melting, the flow of waters would slacken and permit the finer silts to settle slowly and form a dense layer of darker clay. Each passing year would therefore be marked by two alternating layers of gravel and clay, each pair being a yearly cycle or "varve." The principle is exactly the same as that by which we measure the age of a tree by the number of rings of growth. The Great Clay Calendar Banded Glacial From New Haven, Collected by Dr. E.Clay Conn. Antevs Fortunately the layers are not all alike, but can be positively distinguished and identified over wide areas. During an exceptionally warm summer, a deeper gravel layer might be formed or other distinctive variations appear. The annual deposits in one lake can thus be identified with hose in other lakes nearby and by going from one to another, a complete series for thousands of years may be worked out. In fact, they have been traced to the very fronts of existing glaciers in northern Sweden (where just such layers are now being laid down each year), and so connected with our own times. Obviously, no layer could be formed at any point until the ice had melted from the region. The edge of a layer of any date, where it touches bedrock, will therefore mark the edge of the ice sheet at that date. By this method, the stages of retreat of the Baltic Ice Sheet have been carefully dated as shown on the map. The entire record goes back some 13, 500 years, long before the Fundamentalists date of creation. Plenty of Years for Evolution
