^65:4.8 Another outstanding variation of procedure was the late arrival of the Planetary Prince. As a rule, the prince appears on a planet about the time of will development; and if such a plan had been followed, Caligastia might have come to Urantia even during the lifetimes of Andon and Fonta instead of almost 500,000 years later, simultaneously with the appearance of the 6 Sangik races.

^65:4.9 On an ordinary inhabited world a Planetary Prince would have been granted on the request of the Life Carriers at, or sometime after, the appearance of Andon and Fonta. But Urantia having been designated a life-modification planet, it was by preagreement that the Melchizedek observers, 12 in number, were sent as advisers to the Life Carriers and as overseers of the planet until the subsequent arrival of the Planetary Prince. These Melchizedeks came at the time Andon and Fonta made the decisions which enabled Thought Adjusters to indwell their mortal minds.

^65:4.10 ¶ On Urantia the endeavours of the Life Carriers to improve the Satania life patterns necessarily resulted in the production of many apparently useless forms of transition life. But the gains already accrued are sufficient to justify the Urantia modifications of the standard life designs.

^65:4.11 It was our intention to produce an early manifestation of will in the evolutionary life of Urantia, and we succeeded. Ordinarily, will does not emerge until the coloured races have long been in existence, usually first appearing among the superior types of the red man. Your world is the only planet in Satania where the human type of will has appeared in a precoloured race.

^65:4.12 But in our effort to provide for that combination and association of inheritance factors which finally gave rise to the mammalian ancestors of the human race, we were confronted with the necessity of permitting hundreds and thousands of other and comparatively useless combinations and associations of inheritance factors to take place. Many of these seemingly strange by-products of our efforts are certain to meet your gaze as you dig back into the planetary past, and I can well understand how puzzling some of these things must be to the limited human viewpoint.

5. LIFE-EVOLUTION VICISSITUDES

^65:5.1 It was a source of regret to the Life Carriers that our special efforts to modify intelligent life on Urantia should have been so handicapped by tragic perversions beyond our control: the Caligastia betrayal and the Adamic default.

^65:5.2 But throughout all of this biologic adventure our greatest disappointment grew out of the reversion of certain primitive plant life to the prechlorophyll levels of parasitic bacteria on such an extensive and unexpected scale. This eventuality in plant-life evolution caused many distressful diseases in the higher mammals, particularly in the more vulnerable human species. When we were confronted with this perplexing situation, we somewhat discounted the difficulties involved because we knew that the subsequent admixture of the Adamic life plasm would so reinforce the resisting powers of the resulting blended race as to make it practically immune to all diseases produced by the vegetable type of organism. But our hopes were doomed to disappointment owing to the misfortune of the Adamic default.

^65:5.3 The universe of universes, including this small world called Urantia, is not being managed merely to meet our approval nor just to suit our convenience, much less to gratify our whims and satisfy our curiosity. The wise and all-powerful beings who are responsible for universe management undoubtedly know exactly what they are about; and so it becomes Life Carriers and behoves mortal minds to enlist in patient waiting and hearty co-operation with the rule of wisdom, the reign of power, and the march of progress.

^65:5.4 There are, of course, certain compensations for tribulation, such as Michael’s bestowal on Urantia. But irrespective of all such considerations, the later celestial supervisors of this planet express complete confidence in the ultimate evolutionary triumph of the human race and in the eventual vindication of our original plans and life patterns.

6. EVOLUTIONARY TECHNIQUES OF LIFE

^65:6.1 It is impossible accurately to determine, simultaneously, the exact location and the velocity of a moving object; any attempt at measurement of either inevitably involves change in the other. The same sort of a paradox confronts mortal man when he undertakes the chemical analysis of protoplasm. The chemist can elucidate the chemistry of dead protoplasm, but he cannot discern either the physical organization or the dynamic performance of living protoplasm. Ever will the scientist come nearer and nearer the secrets of life, but never will he find them and for no other reason than that he must kill protoplasm in order to analyse it. Dead protoplasm weighs the same as living protoplasm, but it is not the same.

^65:6.2 ¶ There is original endowment of adaptation in living things and beings. In every living plant or animal cell, in every living organism — material or spiritual — there is an insatiable craving for the attainment of ever-increasing perfection of environmental adjustment, organismal adaptation, and augmented life realization. These interminable efforts of all living things evidence the existence within them of an innate striving for perfection.

^65:6.3 The most important step in plant evolution was the development of chlorophyll-making ability, and the second greatest advance was the evolution of the spore into the complex seed. The spore is most efficient as a reproductive agent, but it lacks the potentials of variety and versatility inherent in the seed.

^65:6.4 One of the most serviceable and complex episodes in the evolution of the higher types of animals consisted in the development of the ability of the iron in the circulating blood cells to perform in the double role of oxygen carrier and carbon dioxide remover. And this performance of the red blood cells illustrates how evolving organisms are able to adapt their functions to varying or changing environment. The higher animals, including man, oxygenate their tissues by the action of the iron of the red blood cells, which carries oxygen to the living cells and just as efficiently removes the carbon dioxide. But other metals can be made to serve the same purpose. The cuttlefish employs copper for this function, and the sea squirt utilizes vanadium.

^65:6.5 The continuation of such biologic adjustments is illustrated by the evolution of teeth in the higher Urantia mammals; these attained to 36 in man’s remote ancestors, and then began an adaptative readjustment toward 32 in the dawn man and his near relatives. Now the human species is slowly gravitating toward 28. The process of evolution is still actively and adaptatively in progress on this planet.

^65:6.6 But many seemingly mysterious adjustments of living organisms are purely chemical, wholly physical. At any moment of time, in the blood stream of any human being there exists the possibility of upward of 15,000,000 chemical reactions between the hormone output of a dozen ductless glands.

^65:6.7 ¶ The lower forms of plant life are wholly responsive to physical, chemical, and electrical environment. But as the scale of life ascends, one by one the mind ministries of the 7 adjutant spirits become operative, and the mind becomes increasingly adjustive, creative, co-ordinative, and dominative. The ability of animals to adapt themselves to air, water, and land is not a supernatural endowment, but it is a superphysical adjustment.
