65:2.14 (733.4) Since the quality of the mind capacity for development in this eastern group was so definitely inferior to that of the other two groups, the Life Carriers, with the consent of their superiors, so manipulated the environment as further to circumscribe these inferior prehuman strains of evolving life. To all outward appearances the elimination of these inferior groups of creatures was accidental, but in reality it was altogether purposeful.
65:2.15 (733.5) Later in the evolutionary unfolding of intelligence, the lemur ancestors of the human species were far more advanced in North America than in other regions; and they were therefore led to migrate from the arena of western life implantation over the Bering land bridge and down the coast to southwestern Asia, where they continued to evolve and to benefit by the addition of certain strains of the central life group. Man thus evolved out of certain western and central life strains but in the central to near-eastern regions.
65:2.16 (733.6) In this way the life that was planted on Urantia evolved until the ice age, when man himself first appeared and began his eventful planetary career. And this appearance of primitive man on earth during the ice age was not just an accident; it was by design. The rigors and climatic severity of the glacial era were in every way adapted to the purpose of fostering the production of a hardy type of human being with tremendous survival endowment. 3. The Fostering of Evolution
65:3.1 (733.7) It will hardly be possible to explain to the present-day human mind many of the queer and apparently grotesque occurrences of early evolutionary progress. A purposeful plan was functioning throughout all of these seemingly strange evolutions of living things, but we are not allowed arbitrarily to interfere with the development of the life patterns after they have once been set in operation.
65:3.2 (733.8) Life Carriers may employ every possible natural resource and may utilize any and all fortuitous circumstances which will enhance the developmental progress of the life experiment, but we are not permitted mechanically to intervene in, or arbitrarily to manipulate the conduct and course of, either plant or animal evolution.
65:3.3 (733.9) You have been informed that Urantia mortals evolved by way of primitive frog development, and that this ascending strain, carried in potential in a single frog, narrowly escaped extinction on a certain occasion. But it should not be inferred that the evolution of mankind would have been terminated by an accident at this juncture. At that very moment we were observing and fostering no less than one thousand different and remotely situated mutating strains of life which could have been directed into various different patterns of prehuman development. This particular ancestral frog represented our third selection, the two prior life strains having perished in spite of all our efforts toward their conservation.
65:3.4 (734.1) Even the loss of Andon and Fonta before they had offspring, though delaying human evolution, would not have prevented it. Subsequent to the appearance of Andon and Fonta and before the mutating human potentials of animal life were exhausted, there evolved no less than seven thousand favorable strains which could have achieved some sort of human type of development. And many of these better stocks were subsequently assimilated by the various branches of the expanding human species.
65:3.5 (734.2) Long before the Material Son and Daughter, the biologic uplifters, arrive on a planet, the human potentials of the evolving animal species have been exhausted. This biologic status of animal life is disclosed to the Life Carriers by the phenomenon of the third phase of adjutant spirit mobilization, which automatically occurs concomitantly with the exhaustion of the capacity of all animal life to give origin to the mutant potentials of prehuman individuals.
65:3.6 (734.3) Mankind on Urantia must solve its problems of mortal development with the human stocks it has—no more races will evolve from prehuman sources throughout all future time. But this fact does not preclude the possibility of the attainment of vastly higher levels of human development through the intelligent fostering of the evolutionary potentials still resident in the mortal races. That which we, the Life Carriers, do toward fostering and conserving the life strains before the appearance of human will, man must do for himself after such an event and subsequent to our retirement from active participation in evolution. In a general way, man’s evolutionary destiny is in his own hands, and scientific intelligence must sooner or later supersede the random functioning of uncontrolled natural selection and chance survival.
