80:2.1 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.
80:2.2 The purer indigo elements moved southward to the forests of central Africa, where they have ever since remained. The more mixed groups spread out in three directions: The superior tribes to the west migrated to Spain and thence to adjacent parts of Europe, forming the nucleus of the later Mediterranean long-headed brunet races. The least progressive division to the east of the Sahara plateau migrated to Arabia and thence through northern Mesopotamia and India to faraway Ceylon. The central group moved north and east to the Nile valley and into Palestine.
80:2.3 It is this secondary Sangik substratum that suggests a certain degree of kinship among the modern peoples scattered from the Deccan through Iran, Mesopotamia, and along both shores of the Mediterranean Sea.
80:2.4 About the time of these climatic changes in Africa, England separated from the continent, and Denmark arose from the sea, while the isthmus of Gibraltar, protecting the western basin of the Mediterranean, gave way as the result of an earthquake, quickly raising this inland lake to the level of the Atlantic ocean. Presently the Sicilian land bridge submerged, creating one sea of the Mediterranean and connecting it with the Atlantic Ocean. This cataclysm of nature flooded scores of human settlements and occasioned the greatest loss of life by flood in all the world's history.
80:2.5 This engulfment of the Mediterranean basin immediately curtailed the westward movements of the Adamites, while the great influx of Saharans led them to seek outlets for their increasing numbers to the north and east of Eden. As the descendants of Adam journeyed northward from the valleys of the Tigris and Euphrates, they encountered mountainous barriers and the then expanded Caspian Sea. And for many generations the Adamites hunted, herded, and tilled the soil around their settlements scattered throughout Turkestan. Slowly this magnificent people extended their territory into Europe. But now the Adamites enter Europe from the east and find the culture of the blue man thousands of years behind that of Asia since this region has been almost entirely out of touch with Mesopotamia.
