As stated before, a very appropriate analogy to the relationship among the various races of the species is the relationship among the siblings within a family. As explained in the book, the human species has now evolved to the adolescent stage of development. The ancestors of the Chinese people have traveled the most through space, all the way from Africa to China, and so form the youngest modern civilization, which can be considered to be analogous to youth of some 13 years of age. The ancestors of the African civilization have traveled the least through space, as they remained in Africa, and so form the oldest civilization, which can be considered to be analogous to youth of some 17 years of age. The Indo-European civilization, which includes speakers of English, is genetically much older than speakers of Chinese, yet it is younger than the civilization of Africa, and can be considered to be analogous to youth of some 16 years of age.
All races are therefore at a very similar age of development.
The differences in age are very small, compared with, for example, modern people relative to our ancestors in the stone age. However small the differences in the age of the various races are, they are still very significant, and they are now measurable. When children are born, they have no idea about the organization of nature, and they have no language that will help them to organize their understanding of nature. Newborn children have lived through too little time to be well aware of time. As children age, they evolve to a better understanding of the organization of nature.
