49:1.7

The process of planetary evolution is orderly and controlled. The development of higher organisms from lower groupings of life is not accidental. Sometimes evolutionary progress is temporarily delayed by the destruction of certain favorable lines of life plasm carried in a selected species. It often requires ages upon ages to recoup the damage occasioned by the loss of a single superior strain of human heredity. These selected and superior strains of living protoplasm should be jealously and intelligently guarded when once they make their appearance. And on most of the inhabited worlds these superior potentials of life are valued much more highly than on Urantia.
