Lapps and the Eskimos are blends of Andonite and Sangik-blue races. Their skeletal structures come the nearest to preserving the aboriginal Andonic type. But the Adamites and the Nodites have become so admixed with the other races that they can be detected only as a generalized Caucasoid order.

In general, therefore, as the human remains of the last twenty thousand years are unearthed, it will be impossible clearly to distinguish the five original types. Study of such skeletal structures will disclose that mankind is now divided into approximately three classes:

1. The Caucasoid—the Andite blend of the Nodite and Adamic stocks, further modified by primary and (some) secondary Sangik admixture and by considerable Andonic crossing. The Occidental white races, together with some Indian and Turanian peoples, are included in this group. The unifying factor in this division is the greater or lesser proportion of Andite inheritance.

2. The Mongoloid—the primary Sangik type, including the original red, yellow, and blue races. The Chinese and Amerinds belong to this group. In Europe the Mongoloid type has been modified by secondary Sangik and Andonic mixture; still more by Andite infusion. The Malayan and other Indonesian peoples are included in this classification, though they contain a high percentage of secondary Sangik blood.

3. The Negroid—the secondary Sangik type, which originally included the orange, green, and indigo races. This is the type best illustrated by the Negro, and it will be found through Africa, India, and Indonesia wherever the secondary Sangik races located.

In North China there is a certain blending of Caucasoid and Mongoloid types; in the Levant the Caucasoid and Negroid have intermingled; in India, as in South America, all three types are represented. And the skeletal characteristics of the three surviving types still persist and help to identify the later ancestry of present-day human races.

Biologic evolution and cultural civilization are not necessarily correlated; organic evolution in any age may proceed unhindered in the very midst of cultural decadence. But when lengthy periods of human history are surveyed, it will be observed that eventually evolution and culture become related as cause and effect. Evolution may advance in the absence of culture, but cultural civilization does not flourish without an adequate background of antecedent racial progression. Adam and Eve introduced no art of civilization foreign to the progress of human society, but the Adamic blood did augment the inherent ability of the races and did accelerate the pace of economic development and industrial progression. Adam's bestowal improved the brain power of the races, thereby greatly hastening the processes of natural evolution.

Through agriculture, animal domestication, and improved architecture, mankind gradually escaped the worst of the incessant struggle to live and began to cast about to find wherewith to sweeten the process of living; and this was the beginning of the striving for higher and ever higher standards of material comfort. Through manufacture and industry man is gradually augmenting the pleasure content of mortal life.
