From the inception of life on an evolutionary planet to the time of its final flowering in the era of light and life, there appear upon the stage of world action at least seven epochs of human life. These successive ages are determined by the planetary missions of the divine Sons, and on an average inhabited world these epochs appear in the following order:

1. Pre-Planetary Prince Man.

2. Post-Planetary Prince Man.

3. Post-Adamic Man.

4. Post-Magisterial Son Man.

5. Postbestowal Son Man.

6. Post-Teacher Son Man.

7. The Era of Light and Life.

The worlds of space, as soon as they are physically suitable for life, are placed on the registry of the Life Carriers, and in due time these Sons are dispatched to such planets for the purpose of initiating life. The entire period from life initiation to the appearance of man is designated the prehuman era and precedes the successive mortal epochs considered in this narrative.

From the time of man's emergence from the animal level—when he can choose to worship the Creator—to the arrival of the Planetary Prince, mortal will creatures are called primitive men. There are six basic types or races of primitive men, and these early peoples successively appear in the order of the spectrum colors, beginning with the red. The length of time consumed in this early life evolution varies greatly on the different worlds, ranging from one hundred and fifty thousand years to over one million years of Urantia time.

The evolutionary races of color—red, orange, yellow, green, blue, and indigo—begin to appear about the time that primitive man is developing a simple language and is beginning to exercise the creative imagination. By this time man is well accustomed to standing erect.

Primitive men are mighty hunters and fierce fighters. The law of this age is the physical survival of the fittest; the government of these times is wholly tribal. During the early racial struggles on many worlds some of the evolutionary races are obliterated, as occurred on Urantia. Those who survive are usually subsequently blended with the later imported violet race, the Adamic peoples.

In the light of subsequent civilization, this era of primitive man is a long, dark, and bloody chapter. The ethics of the jungle and the morals of the primeval
