The red and the yellow races are the only human stocks that ever achieved a high degree of civilization apart from the influences of the Andites. The oldest Amerindian culture was the Onamonalonton center in California, but this had long since vanished by 35,000 b.c. In Mexico, Central America, and in the mountains of South America the later and more enduring civilizations were founded by a race predominantly red but containing a considerable admixture of the yellow, orange, and blue.
