Marked changes were taking place in the fauna of the planet. The sea life was undergoing great modification; most of the present-day orders of marine life were in existence, and foraminifers continued to play an important role. The insect life was much like that of the previous era. The Florissant fossil beds of Colorado belong to the later years of these far-distant times. Most of the living insect families go back to this period, but many then in existence are now extinct, though their fossils remain.

During most of the ice age England was connected by land with France, while later on Africa was joined to Europe by the Sicilian land bridge. At the time of the Andonic migrations there was a continuous land path from England in the west on through Europe and Asia to Java in the east; but Australia was again isolated, which further accentuated the development of its own peculiar fauna.

The largest of the dinosaurs originated in western North America. These monstrous reptiles are buried throughout the Rocky Mountain regions, along the whole of the Atlantic coast of North America, over western Europe, South Africa, and India, but not in Australia.

The presence of roots of trees as they grew in the clay underlying the present coal beds demonstrates that coal was formed exactly where it is now found. Coal is the water-preserved and pressure-modified remains of the rank vegetation growing in the bogs and on the swamp shores of this faraway age. Coal layers often hold both gas and oil. Peat beds, the remains of past vegetable growth, would be converted into a type of coal if subjected to proper pressure and heat. Anthracite has been subjected to more pressure and heat than other coal.

Writing progressed up through the stages of the “message stick,” knotted cords, picture writing, hieroglyphics, and wampum belts, to the early symbolic alphabets. Message sending evolved from the primitive smoke signal up through runners, animal riders, railroads, and airplanes, as well as telegraph, telephone, and wireless communication.

85,000,000 years ago the Bering Strait closed, shutting off the cooling waters of the northern seas. Theretofore the marine life of the Atlantic-Gulf waters and that of the Pacific Ocean had differed greatly, owing to the temperature variations of these two bodies of water, which now became uniform.

390,000,000 years ago the land was still elevated. Over parts of eastern and western America and western Europe may be found the stone strata laid down during these times, and these are the oldest rocks which contain trilobite fossils. There were many long fingerlike gulfs projecting into the land masses in which were deposited these fossil-bearing rocks.

250,000 years ago the sixth and last glaciation began. And despite the fact that the northern highlands had begun to sink slightly, this was the period of greatest snow deposition on the northern ice fields.

Away from the ice the land and water life of the world was little changed. Between the ice invasions the climate was about as mild as at present, perhaps a little warmer. The glaciers were, after all, local phenomena, though they spread out to cover enormous areas. The coastwise climate varied greatly between the times of glacial inaction and those times when enormous icebergs were sliding off the coast of Maine into the Atlantic, slipping out through Puget Sound into the Pacific, and thundering down Norwegian fiords into the North Sea.

1,500,000 years ago the first great glacier was retreating northward. In the meantime, enormous quantities of snow had been falling on Greenland and on the northeastern part of North America, and erelong this eastern ice mass began to flow southward. This was the second invasion of the ice.

But it is a fallacy to presume to classify the white peoples as Nordic, Alpine, and Mediterranean. There has been altogether too much blending to permit such a grouping. At one time there was a fairly well-defined division of the white race into such classes, but widespread intermingling has since occurred, and it is no longer possible to identify these distinctions with any clarity. Even in 3000 b.c. the ancient social groups were no more of one race than are the present inhabitants of North America.

210,000,000 years ago the warm-water arctic seas covered most of North America and Europe. The south polar waters inundated South America and Australia, while both Africa and Asia were highly elevated.

The early expansion of the violet race into Europe was cut short by certain rather sudden climatic and geologic changes. With the retreat of the northern ice fields the water-laden winds from the west shifted to the north, gradually turning the great open pasture regions of Sahara into a barren desert. This drought dispersed the smaller-statured brunets, dark-eyed but long-headed dwellers of the great Sahara plateau.

This last glacier was one hundred thousand years advancing, and it required a like span of time to complete its northern retreat. The temperate regions have been free from the ice for a little over fifty thousand years.

The North American Indians never came in contact with even the Andite offspring of Adam and Eve, having been dispossessed of their Asiatic homelands some fifty thousand years before the coming of Adam. During the age of Andite migrations the pure red strains were spreading out over North America as nomadic tribes, hunters who practiced agriculture to a small extent. These races and cultural groups remained almost completely isolated from the remainder of the world from their arrival in the Americas down to the end of the first millennium of the Christian era, when they were discovered by the white races of Europe. Up to that time the Eskimos were the nearest to white men the northern tribes of red men had ever seen.

The rapid-transit facilities, which make it practical greatly to extend the city boundaries, are under municipal control. The city fire departments are supported by the fire-prevention and insurance foundations, and all buildings, in city or country, are fireproof — have been for over seventy-five years.

The Pacific coast, usually above water during the continental submergences, went down excepting the southern part of California and a large island which then existed in what is now the Pacific Ocean. This ancient California sea was rich in marine life and extended eastward to connect with the old sea basin of the midwestern region.

550,000 years ago the advancing glacier again pushed man and the animals south. But this time man had plenty of room in the wide belt of land stretching northeast into Asia and lying between the ice sheet and the then greatly expanded Black Sea extension of the Mediterranean.

The most important step in plant evolution was the development of chlorophyll-making ability, and the second greatest advance was the evolution of the spore into the complex seed. The spore is most efficient as a reproductive agent, but it lacks the potentials of variety and versatility inherent in the seed.

Throughout the oceanic ages, enormous layers of fossil-free stratified stone were deposited on this ancient ocean bottom. (Limestone can form as a result of chemical precipitation; not all of the older limestone was produced by marine-life deposition.) In none of these ancient rock formations will there be found evidences of life; they contain no fossils unless, by some chance, later deposits of the water ages have become mixed with these older prelife layers.
