Evolution: An Investigation and a Critique Part 1

Evolution.

by Theodore Graebner.

PREFATORY.

I first read Charles Darwin's "Origin of Species" in the library of my sainted uncle, John Schaller, at New Ulm, Minnesota, in 1892. I did not comprehend all of it then, a cause, to me, of considerable chagrin, for which I later found some consolation in the opinion of Dr. Frederick Lynch, who p.r.o.nounces Darwin's epochal work "one of the two most difficult books in the English language." But like many others, I understood enough of Darwin's book to catch glimpses of the grandeur of the conception which underlies its argumentation. It was then that my beloved uncle, out of that wide and accurate reading which so frequently astonished his friends, and with that penetrating dialectic of his, opened my eyes to certain fallacies in Darwin's argument, especially to the fatal weakness of the chapter on Instinct. The reading of St. George Mivart's book "The Genesis of Species" later convinced me of the accuracy of my uncle's judgment. But the fascination of the subject persisted, and for a time Herbert Spencer's "Synthetic Philosophy," by the comprehensiveness of its induction and its vast array of data, exercised its thrall. Alfred Russel Wallace's "Darwinism," Huxley's "Lectures on Evolution," Tyndall's "The Beginning of Things," Grant Allen's "The Evolutionist at Large," Eimer's "Orthogenesis," Clodd's "Story of Creation," occupied me in turn, until the apodictic presentation of John Fiske's Essays on Darwinism, no less than the open and haggard opposition to Christianity which prevails in Huxley's "Science and Hebrew Tradition" and in Spencer's chapters on "The Unknowable" (so the Synthetic Philosophy denominates G.o.d), caused a revulsion of sentiment,--the anti-religious bias of evolution standing forth the clearer to my mind, the longer I occupied myself with the subject.

I determined to investigate for myself the data on which the speculations whose mazes I had trod these years were built up. The leisure hours of three years were devoted to the study of first-hand sources of Comparative Religion. The result of this research was deposited in two articles contributed to the _Theological Quarterly_ in 1906 and 1907. I fear that the forbidding character of the foot-notes served as an effective deterrent to the reading of these articles. I have now given, in several chapters of this little volume, in popular language the argument against evolution to be derived from the study of Religion. The reading of Le Conte's and Dana's text-books of geology and various other treatises supplied the data on palaeontology embodied in the first chapters of the book. The notable circulus in concludendo ("begging the question") of which evolutionists here are guilty was first pointed out to me by Prof. Tingelstad of Decorah, Iowa, who was in 1908 taking a course in Evolution at Chicago University, and who called on me for discussion of the doctrine as he received it from "head-quarters."

An an excursus in the subject of Pedagogy, I have treated in my Seminary lectures the past years, under the head of natural sciences, the argument against evolution, and the outlines of these lectures have furnished the framework for the present volume. It is hoped that especially our young men and women who take courses at our universities will examine the case against the fascinating and in some respects magnificent conception of evolution as this case is presented in the following chapters. I realize that they, as well as intelligent readers generally, may not meet with confidence the statements of a theologian on a scientific question, least of all when he essays to treat such a question from the standpoint of science. He is presumed to be at home in theology, but a stranger in the domain of geology, astronomy, and biology. It is for the purpose of obtaining a hearing at all that these introductory remarks are written. But the argument must stand on its own merits. The writer will now retire to the background. The facts shall speak.

EVOLUTION.

CHAPTER ONE.

An Outline of the Theory.

Definition.

Evolution is a name comprehending certain theories which seek to account for all operations of nature as carried on according to fixed laws by means of forces resident in nature. Prof. J. LeConte of the University of California defines evolution as: "Continuous progressive change according to certain laws and by means of resident forces." Evolution is a theory, a philosophy, it is not a science. The theory is called _organic_ evolution in its relation to living forms (plant and animal life), _cosmic_ evolution, inasmuch as attempts have been made to account by certain laws and the working of resident forces for the development of the universe,--the earth, the sun, and the starry heavens. Also the development of society, of religion, morals, politics, art, and mechanical inventions is accounted for on the theory that there are forces which, acting according to certain laws, have through many changes made human life and inst.i.tutions as we see them today.

The doctrine of Evolution briefly stated, is as follows: That in some infinitely remote period in the past, how or from whence science does not affirm, there appeared matter and force; that within matter and in a.s.sociation with force there also appeared a primordial cell, how or from whence no man knoweth, in which there was a spark of life; and that from this cell all things animate have emerged, being controlled by certain laws variously stated by various evolutionists; that these laws in connection with the modifying influences of environment (surroundings,--soil, climate, etc.) account for and explain the various species that have existed in the past and now exist upon earth, man included. That there are no gaps in the process but that there is demonstrable a steady ascent from lower to higher (simple to more complex) forms of life, until man is reached, the acknowledged highest product of evolution.

The extreme evolutionists hold that all the power and potency of the universe was stored up in that primordial cell, and that all things have been worked out without any superintending agency other than the forces resident in matter. Every operation of G.o.d is ruled out, or deemed unnecessary. This is sometimes called atheistic evolution.

The theistic evolutionist ("theistic" from "theism," the belief in a personal G.o.d) makes place for G.o.d in the beginning and all along the line of development, as overlooking the process, perhaps reinforcing and to a certain extent directing the energy, but not interfering with the fixed law or rule of evolution. According to theistic evolution, G.o.d did not create plants and animals as separate species (as related in Genesis 1) but created matter as a crude form and placed it under certain laws, by which this matter was, during untold ages, gradually evolved into worlds. That out of this matter, called inorganic, plants came into existence, from some germ or property existing in matter. The origin of animal life is explained in various ways by the so-called theistic evolutionists. Some hold that the primordial plant life contained potentially the lowest and simplest principles of animal life, and from it the simplest animal forms were evolved; that from these latter were evolved forms a little higher, until, after long ages, all the gradations were pa.s.sed through until man, the highest form, was the result. Others believe that there is such an essential difference between plants and animals that the latter could not have come from the former, that there must be a new start on the animal side of life.

Therefore they claim that when the evolutionary development of matter reached a certain stage, G.o.d appeared on the scene and endowed certain forms with the principle of animal life, in its lowest elements. These lowest forms of animal life then entered upon a series of evolutionary growth, each lower form evolving one a little more complex, each series gaining the use of and developing organs which existed essentially in the lower form but were small, imperfect, and useless, because not needed. Thus the hand and arm in man are structurally or essentially the same as the leg of the brute, the wing of the bird, the flipper of the whale, and the fin of the fish; and the endeavor to adapt itself to the water caused the bird to develop a fin, as by a similar process the fore-leg of brutes developed into the human arm and hand.

For our present consideration, we need not distinguish between atheistic and theistic evolution, as the latter is subject to the fundamental objections urged against evolution in general, and is, like atheistic evolution, without a single fact to support it and in direct contradiction of all that is known of the laws in operation now, and as far back as knowledge penetrates. Moreover, so-called "theistic"

evolution is universally approved by infidels and skeptics and is used by them as a favorite means of a.s.sault on revealed Truth.

Historical Review.

While in our own day the names of certain English and German scientists (Darwin, Spencer, Huxley, Tyndall, Romanes, Buechner, Vogt, Haeckel) are inseparably connected with a history of this hypothesis, its roots are found far back in the early ages of Greek philosophy. A theory of evolutionary development was first propounded by Greek thinkers living about 600 years B. C. The human mind is ever on the search for unifying principles, principles which account for entire groups of natural phenomena, and not for isolated phenomena only. The Greek mind sought a principle by which to account for the manifold and diverse forms of life in nature. Whence do all things come? How have they come to be what they are? Questions about the nature of the universe in which we live have been asked from the very beginning. The moment the human mind began to reflect the notion that the vegetation which covers the earth, the animals which inhabit it, the rocks and hills, the mountains and valleys which const.i.tute its physical features, may have undergone changes in past time, and that all the phenomena which const.i.tute the animal, vegetable and mineral worlds as they now exist, are but modifications of other forms which have had their day and their philosophy, the idea of development became prominent. The early Greek philosophers were the first to attempt answers to these problems. Many of them held that all things natural sprang from what they called the original elements--fire, air, earth, water. Anaximander held that animals were begotten from the earth by means of heat and moisture; and that man was developed from other beings different in form. Empedocles had a fantastic theory, viz., that the various parts of man and animals at first existed independently, and that these--for instance, arms, legs, feet, eyes, etc., gradually combined--perhaps after the manner in which automobiles are a.s.sembled; and that these combinations became capable of existing and even of propagating and reproducing themselves. Anaxagoras was of opinion that animals and plants sprang from the earth by means of germs carried in the atmosphere which gave fecundity to the earth. Aristotle held opinions not very unlike those of our own day. All of which goes to show that speculation about the origin of the universe and the why and wherefore of living things did not come into existence with the Darwinian hypothesis and that the doctrine of descent with modification as an explanation of all biological phenomena antedates by over two thousand years the publication of the "Origin of Species."

In modern times a theory of development was first suggested by Goethe in his _"Italienische Reise."_ Acting under the same mental urge for seeing diverse forms under a unifying principle, Goethe looked for the original form of plant life, the _Urpflanze_, the plant which would be at once simple enough to stand for a type of all plants and yet susceptible to variation in so many directions that all plants might derive from it their origin. Goethe has also clothed this conception in poetic form.

The first philosophic statement of the hypothesis is found in Immanuel Kant's _"Kritik der Urteilskraft,"_ 1790. In paragraph 80 we find a discussion of the similarity between so many species of animals, not only in their bony structure, but also in the arrangement of their other parts, a similarity which, says Kant, "casts a ray of hope," that all forms may be traced back to original simple forms, to "a generation from a common ancestor," rising from the lowest forms to man, "according to mechanical laws." Kant a.s.sumes that, for instance, certain aquatic animals by and by formed into amphibia, and from these after some generations were produced land animals. A treatise of the same philosopher ent.i.tled _"Presumable Origin of Humanity"_ suggests that man in the early age of the world was developed from "mere animal creatures."

Even a universal law of world-formation (cosmic evolution) was set forth by Kant in a work which he published anonymously in 1775.

In its relations to animal life a development theory was first clearly set forth by Karl Ernst von Baer (died 1876). In his _"Entwickelungsgeschichte der Tiere"_ (1828), the author explains "Entwickelung" as a progress from simple to complex forms. He believes that in evolution there is a fundamental idea that "goes through all the forms of cosmic and animal development." A predecessor of von Baer had been the Frenchman, Lamarck. From von Baer, Herbert Spencer, about 1850, adopted the definition of evolution.

The hypothesis entered a new phase through Charles Darwin's epochmaking work: _"The Origin of Species."_ The keynote of Darwin's theory is Natural Selection, by which term the development of all living forms is referred to the working of certain laws which in the reproduction of plants and animals preserved those individuals which were best fitted to survive the struggle for existence. The Darwinian theory may be summarized thus:

The Darwinian Hypothesis.

1. Every kind of animal and plant tends to increase in numbers in a geometrical progression.

2. Every kind of animal and plant transmits a general likeness, with individual differences, to its offspring.

3. Past time has been practically infinite.

4. Every individual has to endure a very severe struggle for existence, owing to the tendency to geometrical increase of all kinds of animals and plants, while the total animal and vegetable population (man and his agency excepted) remains almost stationary.

5. Thus, every variation of a kind tending to save the life of the individual possessing it, or to enable it more surely to propagate its kind, will in the long run be preserved and will transmit its favorable peculiarity to some of its offspring, which peculiarity will thus become intensified till it reaches the maximum degree of utility. On the other hand, individuals presenting unfavorable peculiarities will be ruthlessly destroyed (_Survival of the Fittest_), [tr. note: sic punctuation]

The basis of the theory then is that animals and plants multiply very rapidly and, second, that the offspring always vary slightly from the parents, though generally very closely resembling them. Mr. Alfred Russel Wallace says: "From the first fact or law there follows, necessarily, a constant struggle for existence; because while the offspring always exceeds the parents in number, generally to an enormous extent, yet the total number of living organisms in the world docs not, and can not, increase year by year. Consequently every year, on the average, as many die as are born, plants as well as animals; and the majority die premature deaths. They kill each other in a thousand different ways; they starve each other by some consuming the food that others want; they are destroyed largely by the powers of Nature--by cold and heat, by rain and storm, by flood and fire. There is thus a perpetual struggle among them which shall live and which shall die; and this struggle is tremendously severe, because so few can possibly remain alive--one in five, one in ten, often only one in a hundred or even in a thousand.

"Then comes the question, Why do some live rather than others? If all the individuals of each species were exactly alike in every respect, we could only say it is a matter of chance. But they are not alike. We find that they vary in many different ways. Some are stronger, some swifter, some hardier in const.i.tution, some more cunning. An obscure color may render concealment more easy for some, keener sight may enable others to discover prey or escape from an enemy better than their fellows. Among plants the smallest differences may be useful or the reverse. The earliest and strongest shoots may escape the slug; their greater vigor may enable them to flower and seed earlier in a wet autumn; plants best armed with spines or hairs may escape being devoured; those whose flowers are most conspicuous may be soonest fertilized by insects. We can not doubt that, on the whole, any beneficial variations will give the possessors of it a greater probability of living through the tremendous ordeal they have to undergo. There may be something left to chance, but on the whole _the fittest will survive." (_"Darwinism"_ p. 7)_.

The same writer gives a probable instance of the working of _Natural Selection_ in the origin of certain aquatic birds called dippers. He says: "An excellent example of how a limited group of species has been able to maintain itself by adaptation to one of these 'vacant places' in Nature, is afforded by the curious little birds called dippers or water-ouzels, forming the genus _Cinclus_ and the family _Cindidae_ of naturalists. These birds are something like small thrushes, with very short wings and tail, and very dense plumage. They frequent, exclusively, mountain torrents in the northern hemisphere, and obtain their food entirely in the water, consisting, as it does, of water-beetles, caddis-worms, and other insect-larvae, as well as numerous small fresh-water sh.e.l.ls. These birds, although not far removed in structure from thrushes and wrens, have the extraordinary power of flying under water; for such, according to the best observers, is their process of diving in search of their prey; their dense and somewhat fibrous plumage retaining so much air that the water is prevented from touching their bodies or even from wetting their feathers to any great extent.

Their powerful feet and long curved claws enable them to hold on to stones at the bottom, and thus to retain their position while picking up insects, sh.e.l.ls, etc. As they frequent chiefly the most rapid and boisterous torrents, among rocks, waterfalls, and huge boulders, the water is never frozen over, and they are thus able to live during the severest winters. Only a very few species of dipper are known, all those of the old world being so closely allied to our British bird that some ornithologists consider them to be merely local races of one species; while in North America and the northern Andes there are two other species.

"Here, then, we have a bird, which, in its whole structure, shows a close affinity to the smaller typical perching birds, but which has departed from all its allies in its habits and mode of life, and has secured for itself a place in Nature where it has few compet.i.tors and few enemies. We may well suppose,* [[*Note characteristic phrase "We may suppose that,--." G.]] that, at some remote period, a bird which was perhaps the common and more generalized ancestor of our thrushes, warblers, wrens, etc., had spread widely over the great northern continent, and had given rise to numerous varieties adapted to special conditions of life. Among these some took to feeding on the borders of clear streams, picking out such larvae and mollusks as they could reach in shallow water. When food becomes scarce they would attempt to pick them out of deeper and deeper water, and while doing this in cold weather many would become frozen and starved. But any which possessed denser and more hairy plumage than usual, which was able to keep out the water, would survive; and thus a race would be formed which would depend more and more on this kind of food. Then, following up the frozen streams into the mountains, they would be able to live there during the winter; and as such places afforded them much protection from enemies and ample shelter for their nests and young, further adaptations would occur, till the wonderful power of diving and flying under water was acquired by a true land-bird." (_"Darwinism,"_ p. 81-82.)

Lines of Evidence.

The evolutionary hypothesis (both in its atheistic and theistic or "Christian" form) is understood to rest on the following lines of proof:

i. _Primary:_ The evidence of palaeontology (the study of fossil remains in the rocks). The surface of the earth underneath the top soil consists of layers of rock. Some of them are made up of lime deposits, others of the sh.e.l.ls of sh.e.l.l-fish, others of sand-stone, others of dead trees of the forest (coal), all of them turned hard by the pressure of the weight lying on top of them. Besides these sedimentary rock there are formations like granite, showing the influence of heat. Digging among the sedimentary rock (limestone, sand-stone, princ.i.p.ally) we come across preserved remains of all sorts of animals; some just like those which live to-day, some similar but somewhat different, others quite dissimilar from living animals of our day. These are the fossils. Now, evolutionists a.s.sert that the oldest and simplest animal and plant remains are found in the oldest layers of rock. This is said to prove that in the history of plants and animals on earth, the simplest forms are the oldest and that later the more complex forms were developed from these. LeConte states the matter thus: "The farther back in time we go, the simpler the forms of animal and plant life become, and these forms occur in the order of their origination, just as if they were developed one from another."

2. _Corroborative:_ a) The Argument from Morphology (Structure). The resemblance of the structure of various animal types is a.s.serted to imply a community of descent. "Large groups of species, whose habits are widely different, present certain fundamental likenesses of structure.

The arms of men and apes, the fore-legs of quadrupeds, the paddles of whales, the wings of birds, the breast-fins of fishes, are constructed on the same pattern, but altered to suit their several functions. Nearly all mammals, from the long-necked giraffe to the short-necked elephant, have seven neck-bones; the eyes of the lamprey are moved by six muscles which correspond exactly to the six which work the human eye; all insects and Crustacea--moth and lobster, bettle [tr. note: sic] and cray-fish---are alike composed of twenty segments; the sepals, petals, stamens, and pistils of a flower are all modified leaves arranged in a spire." (Clodd, _"The Story of Creation,"_ p. 102.) These _resemblances_ are looked upon as evidence of a common origin.

b) The Argument from Embryology. The individual animal in embryonic development pa.s.ses through temporary stages which are similar to permanent conditions in some of the lower forms in the same group.

Evolutionists believe that these forms were actually possessed by the ancestors of these animals in the course of their evolution. They hold that the changes which take place in the embryos epitomize the series of changes through which the ancestral forms pa.s.sed. Because the embryos of some four-footed animals have gill-slits, this is pointed out as evidence that land animals are evolved from fishes.

c) Geographical Distribution. In geological time, natural barriers have sprung up which separated the species which have since developed. In this way the existence of marsupials (pouched animals--kangaroo, oppossum) [tr. note: sic] on certain limited areas, the limitation of certain plants to certain islands, etc., are explained.

d) Cla.s.sification. The so-called Tree of Life. All living forms can be arranged in a diagram called the Tree of Life. The Tree has a short trunk, indicating common origin of the living from the non-living, and is divided into two large trunks representing plants and animals respectively. "From each of these start large branches representing cla.s.ses, the larger branches giving off smaller branches representing families, and so on with smaller and smaller branches representing orders and genera, until we come to leaves as representing species, the height of the branch from which they are hanging indicating their place in the growth of the great life-tree." (Clodd, _"Story of Creation,"_ p. 103.) There is an exact gradation from the lowest life forms to the highest. First such simple forms as the sponges and corals, then, through the worms, crabs, oysters, and snail to the fish, and thence through amphibia, reptiles, beasts of prey, ungulates (hoofed animals) and apes to man. Evolutionists say that in this gradation of life we see ill.u.s.trated the evolution of complex from simple forms.

The Descent of Man.

According to the evolutionary hypothesis man is related to the animal kingdom by descent from a brute ancestor, who, apelike in appearance, is the common ancestor of ape and man. The evidence of such derivation is believed to be:

i. Rudiments of structure which were useful in some brute ancestor.

There remain in man a few elementary muscles for twitching the skin, as in the forehead; and it is pointed out that many animals have such muscles at the present time, and it is argued that the ability of some men to move the whole scalp points to the existence of muscles with such function in our brute ancestors. The vermiform appendix in man is termed rudimentary, being but a remnant of the much longer and more complex appendix of the same nature in living animals today.

2. Embryonic Development. Because the young of all animals resemble one another while in the embryo stage, and since such resemblances are found in man, it is concluded that the evolution of man from some related animal form must be accepted as the most reasonable explanation.

3. Some diseases are common to animals and man (tuberculosis, cholera, hydrophobia, etc.).

4. The similarity in structure of man and the apes.
