Laws of Fertility, Role of Natural Selection, and Destructiveness of Mutations
CRSQ Vol 37 No 3 pp 153-158 December 2000
Research into fertility has revealed facts that are incompatible with selectionism, the modern concept of evolution. In whatever species, fertility is never so close to the most productive (optimal) level that it would guarantee survival of most of the offspring. This is a radical contradiction of the selectogenesis theory, which postulates that 1) the level of species fertility has been attained because of selection, and 2) any individual modification of fertility is a matter of adaptation. Neither fertility itself nor its modifications have anything to do with Darwinian adaptation or with increased population growth; actually, they hold the population stabilized within certain limits. It is not the maximization of individual fitness (also known as the reproductive success) that makes up the basic principles of life organization, but allocentrism (the availability of self-limiting properties of species that are advantageous to the ecosystem as a whole, i.e. are good for the mutual benefit of all the species). Despite permanent natural selection for elevated fertility, the distribution of fertility in any species remains invariable. This phenomenon proves the perfect destructiveness of the mutation process. Undoubtedly, mutations that increase fertility have occurred and continue to occur, but do not become fixed because they diminish fitness on the whole. Therefore, selectogenesis cannot be a factor of fertility or of any other character less associated with fitness than fertility, and the creationist concept of the species invariability is thus confirmed. A short classification of cosmogonies is given. Denying the miracle of creation, evolutionism is forced to admit another miraclethe inactivity of the second principle of thermodynamics. Likewise, atheistic science turns out to be inimical to reason and morals.
Laws of Fertility: The Role of Selection and the Meaning of Fertility Modifications
Fertility means here the number of young in a litter of viviparous animals, the number of eggs in a clutch of birds and other egg-laying species, or the number of seeds in a plant formed within one year or growing season. The number of an individuals offspring that survive and live to reach puberty is the reproduction success (RS). In brief, fertility is the potential and RS is the actual productivity of one reproductive cycle of an individual.
The distribution of fertility and RS values at its various levels has been studied in many animal and plant species. Based on these data, the mean fertility x in the population and the optimal fertility x0 (at which RS is maximized) are presented in Table I for various species. In all cases, the mean fertility x is much lower than the optimal fertility x0 (x < x0), so that optimal fertility is often beyond the limits of fertility variation in the population, exceeding many of its values, not only the mean. The relation x < x0 is well known for many species in other taxa and has no exceptions. Most often it has been observed that as RS increases, so does fertility all over the range of its variation; hence it follows that x < x0 (Blagosklonov, 1991; Lack, 1954).
This phenomenon contradicts selectionismthe doctrine according to which the fertility level is determined by selection. If selectionism were true, the mean fertility would coincide with the optimal one, i.e. the equality x = x0 would be fulfilled. Lack (1954) explains this contradiction by adaptive modification of fertility (AMF) corresponding to the given place and time. For example, small clutches are found where there are poor feeding conditions and large ones in good feeding conditions. As a result, the RS increases from small fertility values to large ones, and the fertility distribution reflects that of trophic conditions in the population. Then the mean fertility is equal to the mean value of fertility optimum under heterogeneous feeding conditions of the population. As support for the existence of AMF, Lack points to fertility variations caused by oscillations of feeding conditions (fertility optimum), and gives an example in owls and other predatory vole-eating birds. In years when voles are abundant, the clutches of these birds are larger, whereas in vole-poor years clutch sizes are smaller. Thereby, according to Lack, the mean clutch size is kept at the optimal level, so that under any feeding conditions the fertility level ensures the maximal RS.
In all species, the productivity of large fertility values (in the sense of number of surviving offspring) is usually higher than that of small ones; nevertheless, the mean value of fertility and its limits are maintained at a low level. That is why a constant selection for increased fertility goes on, the strength of which can be measured in two ways: 1) by means of the average coefficient of selection in favor of the most productive (usually the largest) values of fertility in the population, and 2) by means of the selection differential with respect to fertility which, for the sake of comparability in various species, can be expressed in standard deviations s of fertility. These indices of selection for increased fertility in populations are presented in Table II. The average coefficient of selection in favor of the most productive fertility xm in the population is equal to
where u is the mean RS and um = u(xm) is the most RS in the population. It points to a relative reduction of reproduction in a real population as compared to the maximally possible one, such that the individuals in the population as a whole will have the most productive fertility. So, in man, the reproduction in real populations is by 5062% lower than as if all the births consisted of triplets and there were neither singles nor twins. The selection differential (SD) is the difference between the mean values of the character in a group of producers of the next generation and in the population that is sampled. Because of the fact that more fertile individuals produce more offspring and vice versa, the mean value of fertility in the producers is calculated with weights (formula) products of RS ui at fertility xi by its frequency fi, which determine the contribution of the given value of fertility to the next generation. The sum of weights is equal to the mean RS u in the population, so that the absolute SD is
From Table II one can see that the normalized SD, otherwise called the intensity of selection (Kirpichnikov, 1979), has a rather large value in all the species (0.08 < SD/s < 0.62), so that the absolute SD values often exceed 0.5s. According to common sense, it is never negative or even zero, but, what is more important, such a strong selection for increased fertility is also perfectly constant. That is why there are no reasons to believe that a group, interpopulation, selection for decreased fertility which overrules the effect of the individual, intrapopulation, selection is at work. The number of acts of individual selection per unit time would have incommensurably exceeded the same index for group selection. We would have been able to admit the existence of group selection only if frequent extinction of populations or even of ecosystems had happened. It is actually not the case, although in an ecosystem there are a lot of species and the fertility of each of them must be continuously decreasing due to the group selection. Extinction of populations would have been continuously interrupting the biological circulation and would have been catastrophic. So, the main argument against the hypothesis of group selection, and therefore against selectogenesis, is that had there been selectogenesis, no populations with low fertility would have remained, and since group selection eliminates highly fertile populations, everything would have died out and nothing would have remained to conserve.
The Destructiveness of Mutations as a
An extremely important generalization in studies of natural mutagenesis is the idea of its destructiveness. There is always concern about risk of losing the mutant allele due to contamination of the strain by tolerable alleles. The mutation, because of its destructiveness, can never stand competition with the wild type and is usually eliminated. On the other hand, there need be no fear that the mutant allele will be converted to a tolerable one by means of a new muation, i.e. will be improved, and the former muation will be eliminated due to fixation of this new allele in the strain. It is usually assumed that constructive mutations do arise, but in an extremely infrequent fashion, and therefore much more time is required to obtain them than the time during which we usually keep our mutant strains. We are sure to conserve our destructive mutations in the culture thanks to the fact that their conversion to constructive tolerable alleles by means of mutation is, because of the shortage of time, a practically impossible event. The laws of fertility disprove the assumption that eventually a constructive mutation excelling the tolerable allele will be able to arise.
Why is selectogenesis of fertility absent so that a selection-induced shift between any consecutive generations is zero? This is because fertility variations are non-heritable, modification-depentdnet, but are not mutation-induced variations. Much time has passed, however, since the very beginning of any species, enough time for constructive, adaptive mutations to arise. If these had taken place, they would have served, on the strength of their heritability, as material for selectogenesis of fertility. But since this is absent in all species, one has to conclude that all of them, without exception, were destructive, i.e. harmful for survival and therefore they could not serve as material for selectogenesis. Therefore, 1) natural mutagenesis, because of its destructiveness, is not a factor of biogenesis, and 2) all the normal, tolerable alleles of any gene have not arisen by means of mutations, but were the products of creation and were inherent in the species since the moment of its emergence, or more exactly, since the creation of the ecosystem whose part the species is. Any changes in an optimally balanced system can only worsen it, which is the case in the influence of mutation process on tolerable alleles.
Experiments by W. Johannsen (1903) have demonstrated non-heritability of quantitative characters in pure strains. In populations consisting of pure strains that differ in any quantitative character the efficiency of selection is limited by the fact that a pure strain arises with a maximal expression of the character under selection which cannot be further changed by selection. It was supposed that it was possible to promote selection of the character as a result of mutations (Filipchenko, 1923). From the laws of fertility, however, it is quite clear that, because of the absence of constructive mutations, the effect of selection on the character comes across an insurmountable obstacle, from which the absolute impossibility of selectogenesis in general follows.
Cosmogonies and Their Classification
A cosmogony is an idea of origin of the universe (cosmos) and life. Cosmogonies can be divided into two major groups:
For an unequivocal understanding of cosmogonies, it is necessary to explain the terms evolution and evolutionism. Evolution, as Clausius defined it, is any process that goes in accordance with the second principle of thermodynamics, i.e. with an increase in entropy, chaos and dispersion of energy (Berg, 1922). It is in this primary sense that evolution must be understood as nomen preoccupatum whose meaning may not be changed to an opposite one, because this will lead to confusion. Therefore, evolution is always a degradation, decay, and is opposite to progress, i.e. increase of order and complexity of organization. As to evolutionism, or the theory of evolution, it is the erroneous idea that evolution is the source of progress and the cause of the cosmos structurelife and any other systems in the universe. Evolutionism denies the transcendental and the supernatural. It assumes that the universe arose without any interference of the Supreme Will, and that it does not contain any intention or purpose (design) as it is transformed only according to immanent laws. Evolutionism is thereby the opposite of creationismthe theory of a rational creation of the universe by God in a transcendental act or series of acts.
Theistic cosmogonies can be subdivided as follows:
The Creator created the universe once, in a germ containing the potentials of complication, whereupon the universe developed by itself, without any interference of His will, according to immanent laws without any supernatural phenomena. This is a transitive, evolutionistic, hybrid creationism that differs from pure evolutionism by recognition of the primary intention and impulse, after which the Creator desisted and did not interfere with universal processes. Subdivisions of transitive creationism are based on the diversity of evolution theories.
Atheistic cosmogonies are all simply different forms of evolutionism in which God is denied as the Creator at all; matter and the universe are eternal and have neither origin nor end. In them the world develops from the primary chaos into cosmos without participation of the Supreme Will and Design. It happens by immanent laws, but it runs contrary to the second principle of thermodynamics, which is believed not to hinder the worlds progress. Denying supernatural acts of creation, evolutionism is forced to admit a miracle of the second principle of thermodynamics being invalid despite its universal character.
Despite the facts that disprove it, evolutionism is being imposed on science because of its atheism and moral degradationnot for scientific but for ideological and political reasons. A product of atheism, evolutionism claims that mankind is the only intelligence in the universe, thereby justifying the re-making of nature and society in accordance with the false ideals of scientific and technological progress. Wealth is considered to be the main criterion of progress, about which Christ says: You cannot serve both God and Money... What is highly valued among men is detestable in Gods sight (Luke 16:1315). However, atheistic science embodied in evolutionism has conquered the mind.
