The Main Core: I will here give a brief sketch of the progress of opinion on the Origin of Species. Until recently the great majority of naturalists believed that species were immutable productions, and had been separately created. This view has been ably maintained by many authors. Some few naturalists, on the other hand, have believed that species undergo modification, and that the existing forms of life are the descendants by true generation of pre-existing forms. ( The Origin of Species, 6th edition, xii.) Darwin's Five Major Theories of Evolution (Mayr, 2002 ) 1. The non constancy of species (the basic theory of evolution) 2. The descent of all organisms from common ancestors 3. The gradualness of evolution (no saltation, no discontinuities) 4. The multiplication of species (the origin of diversity) 5. Natural selection A Two Part Theory (Sober, 2009 ) 1. The Tree of Life (The Theory of Evolution) 2. Natural Selection (The Mechanism) Two Significant Elements: 1. Common Descent (The Theory of Evolution) 2. Natural Selection (The Mechanism) Waters, Evolution: The idea that biological life on Earth developed from simple forms to more complex ones.(tree of life) A major development in evolution, usually one species changing into another species (Transmutation), or evolution of an organism from a common ancestor (macroevolution). and changes or mutations in a species that do not result in transmutation. The result of these changes or adaptations may be the formation of a new variety of the species (microevolution). Evidences: The Fossil Record, Geographic Distribution of Living Things, Homologous Body Structures, Similarities in Early Development The Fossil Record-Layer show change Geographic. Geographic Distribution of Living Things-similar environments have similar types of organisms Homologous Structures-structures that have different mature forms in different organisms, but develop from the same embryonic tissue Similarities in Early Development نمودار منشا انواع داروین fffffeeerrerewwew Gregory, Ryan, 2009 Mayr, Ernest, (1904 – 2005) Evolution is not merely an idea, a theory, or a concept, but is the name of a process in nature, the occurrence of which can be documented by mountains of evidence that nobody has been able to refute. It is now actually misleading to refer to evolution as a theory, considering the massive evidence that has been discovered over the last 140 years documenting its existence. Evolution is no longer a theory, it is simply a fact (Mayr, 2002, 319). Natural Selection I have called this principle, by which each slight variation, if useful, preserved, by the term of Natural Selection, in order to mark its relation to man’s power of selection. (1859, 61) can we doubt (remembering that many more individuals are born than can possibly survive) that individuals having any advantage, however slight, over others, would have the best chance of surviving and of procreating their kind? On the other hand, we may feel sure that any variation in the least degree injurious would be rigidly destroyed. This preservation of favorable variations and the rejection of injurious variations, I call Natural Selection. (1859, .80–81, 83–84) Evidence: Artificial selection and Natural Selection Natural Selection It may be said that natural selection is daily and hourly scrutinizing, throughout the world, every variation, even the slightest; rejecting that which is bad, preserving and adding up all that is good; silently and insensibly working, whenever and wherever opportunity offers, at the improvement of each organic being in relation to its organic and inorganic conditions of life. We see nothing of these slow changes in progress, until the hand of time has marked the long lapse of ages, and then so imperfect is our view into long past geological ages, that we only see that the forms of life are now different from what they formerly were. I am well aware that this doctrine of natural selection, exemplified in the above imaginary instances, is open to the same objections which were at first urged against Sir Charles Lyell’s noble views on ‘the modern changes of the earth, as illustrative of geology.(1859, 108 -109). Unconscious Natural Selection Over all these causes of change, the accumulative action of selection, whether applied methodically and quickly, or unconsciously and slowly, but more efficiently, seems to have been the predominant power.(1859, 31) As man can produce, and certainly has produced, a great result by his methodical and unconscious means of selection, what may not natural selection effect? Man can act only on external and visible characters: Nature, if I may be allowed to personify the natural preservation or survival of the fittest, cares nothing for appearances, except in so far as they are useful to any being. She can act on every internal organ, on every shade of constitutional difference, on the whole machinery of life.(1859, 85) Unconscious Natural Selection By this process long-continued, which exactly corresponds with what I have called unconscious selection by man, combined, no doubt, in a most important manner with the inherited effects of the increased use of parts, it seems to me almost certain that an ordinary hoofed quadruped might be converted into a giraffe.(1859, 209). The comparison would be in every way fairer with the effects which follow from unconscious selection, that is, the preservation of the most useful or beautiful animals, with no intention of modifying the breed; but by this process of unconscious selection, various breeds have been sensibly changed in the course of two or three centuries.(1859, 309) The Power of Natural Selection Let an architect be compelled to build an edifice with uncut stones, fallen from a precipice. The shape of each fragment may be called accidental; yet the shape of each has been determined by the force of gravity, the nature of the rock, and the slope of the precipice, -- events and circumstances all of which depend on natural laws; but there is no relation between these laws and the purpose for which each fragment is used by the builder. In the same manner the variations of each creature are determined by fixed and immutable laws; but these bear no relation to the living structure which is slowly built up through the power of natural selection... The Variation of Animals and Plants Under Domestication, Darwin (1868, p. 236). Natural Selection Although I am fully convinced of the truth of the views given in this volume under the form of an abstract, I by no means expect to convince experienced naturalists whose minds are stocked with a multitude of facts all viewed, during a long course of years, from a point of view directly opposite to mine. It is so easy to hide our ignorance under such expressions as the ‘plan of creation,’’ ‘‘unity of design,’’ (1859, 480–482) Natural Laws It has been said that I speak of natural selection as an active power or Deity; but who objects to an author speaking of the attraction of gravity as ruling the movements of the planets? Every one knows what is meant and is implied by such metaphorical expressions; and they are almost necessary for brevity. So again it is difficult to avoid personifying the word Nature; but I mean by nature, only the aggregate action and product of many natural laws, and by laws the sequence of events as ascertained by us. With a little familiarity such superficial objections will be forgotten. (1859,Chapter 4). These laws, taken in the largest sense, being Growth with reproduction; Inheritance which is almost implied by reproduction; Variability from the indirect and direct action of the conditions of life, and from use and disuse; a Ratio of Increase so high as to lead to a Struggle for Life, and as a consequence to Natural Selection, entailing Divergence of Character and the Extinction of less improved forms. (1859,Chapter 15). Natural Selection, Mayr Evolution is the result of both chance and necessity. There is indeed a great deal of randomness ("chance") in evolution, particularly in the production of genetic variation, but the second step of natural selection, whether selection or elimination, is an anti chance process. The eye, for instance, is not a chance product. (Mayr, 167). Yet the claims of natural theology ran into considerable difficulties…. Consideration of how God could have carried out his task of Creation raised even more serious difficulties. The manifold adaptations of structure, activity, behavior, and life cycle for each of the millions of species of organisms were far too specific to be explained by general laws. On the other hand, it seemed quite unworthy of creator to believe that he personally arranged every detail in the traits and life cycles of every individual down to the lowest organism. (Mayr, 179) The Cause and Effect in Biology, Mayr, Science, 134 N Natural Selection, Blind Watchmaker Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind's eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of watchmaker in nature, it is the blind watchmaker. Decent of Man Man may be excused for feeling some pride at having risen, though not through his own exertions, to the very summit of the organic scale; and the fact of his having thus risen, instead of having been aboriginally placed there, may give him hope for a still higher destiny in the distant future. But we are not here concerned with hopes or fears, only with the truth as far as our reason permits us to discover it; and I have given the evidence to the best of my ability. We must, however, acknowledge, as it seems to me, that man with all his noble qualities, with sympathy which feels for the most debased, with benevolence which extends not only to other men but to the humblest living creature, with his god-like intellect which has penetrated into the movements and constitution of the solar system with all these exalted powers- Man still bears in his bodily frame the indelible stamp of his lowly origin. (Darwin, Decent of Man 459) از سازگارگرایی، و تکامل داروینی، خدا باوری.2 تا ضد سازگارگرایی Theism and Darwinian Evolution Creationism: that life on earth began some 10,000 to 50,000 years ago by God’s separately creating each species (or each “basic kind” of organism). Inconsistent Deism: the view that God created (i) the universe, (ii) the laws of nature, and (iii) the initial conditions of the universe, and then sat back, allowing everything that happens in nature to be a consequence of those three items. Consistent Interventionist Theisms: God not only produced the (i)-(ii)-(iii) (deism) but also intervened in nature after the universe’s beginning.

An intervention, as I‟ll understand the term, is a cause; it can trigger an event or sustain a process. Physicians do both when they intervene in the lives of their patients. Physician intervention does not entail any breakage in the laws of nature; neither does God‟. ( Sober 2011, 5) Sober a probabilistic model of the evolutionary process is consistent with the thesis that the process is deterministic. If determinism is true, there are hidden variables that affect the evolutionary process. Evolutionary theory says nothing about whether such hidden variables exist. It therefore says nothing about whether there are supernatural hidden variables. Ernst Mayr (1961) emphasized the importance of distinguishing proximate from ultimate causation. Mayr's point can be illustrated by considering the question of why sunflowers turn towards the sun. One answer to this question cites the proximate mechanism inside each sunflower that causes it to do so; the other points to the reason the trait evolved, presumably natural selection. There is no conflict between these two "levels" of explanation. The theistic evolutionist should embrace Mayr's pair of concepts and add a third, maintaining that there is, in addition)., a still more distal level of divine causation. God can direct the evolutionary process in an ultimate sense, though mutations are undirected in a proximate sense. Biology says nothing about the former and theism says nothing about the latter. Sober, 2011 Interventionist Theisms: Atheists may want to reach for Ockham‟s razor at this point and argue that these theories are evidence against the existence of God precisely because these theories show that the God hypothesis is not needed in science. But the inference from “science can explain phenomenon X without invoking the existence of God” to “God does not exist” is shaky (Sober 2010). Evolutionary theory, properly understood does not rule out God’s causing some mutations, the theory does rule this out when you add something to it. But the something else is a philosophical thesis, not a scientific theory at all (Sober, 2013). Atheists who think that evolutionary theory provides the beginning of an argument for disbelieving in God should make it clear that their arguments depend on additional premises that are not vouchsafed by scientific theory or data.
