By 20,000 b.c. the population of western India had already become tinged with the Adamic blood, and never in the history of Urantia did any one people combine so many different races. But it was unfortunate that the secondary Sangik strains predominated, and it was a real calamity that both the blue and the red man were so largely missing from this racial melting pot of long ago; more of the primary Sangik strains would have contributed very much toward the enhancement of what might have been an even greater civilization. As it developed, the red man was destroying himself in the Americas, the blue man was disporting himself in Europe, and the early descendants of Adam (and most of the later ones) exhibited little desire to admix with the darker colored peoples, whether in India, Africa, or elsewhere.
