P722:2, 64:5.1 500,000 years ago the Badonan tribes of the northwestern highlands of India became involved in another great racial struggle. For more than one hundred years this relentless warfare raged, and when the long fight was finished, only about one hundred families were left. But these survivors were the most intelligent and desirable of all the then living descendants of Andon and Fonta.
P722:3, 64:5.2 And now, among these highland Badonites there was a new and strange occurrence. A man and woman living in the northeastern part of the then inhabited highland region began suddenly to produce a family of unusually intelligent children. This was the Sangik family, the ancestors of all of the six colored races of Urantia.
P722:4, 64:5.3 These Sangik children, nineteen in number, were not only intelligent above their fellows, but their skins manifested a unique tendency to turn various colors upon exposure to sunlight. Among these nineteen children were five red, two orange, four yellow, two green, four blue, and two indigo. These colors became more pronounced as the children grew older, and when these youths later mated with their fellow tribesmen, all of their offspring tended toward the skin color of the Sangik parent.
P722:5, 64:5.4 And now I interrupt the chronological narrative, after calling attention to the arrival of the Planetary Prince at about this time, while we separately consider the six Sangik races of Urantia.
