Newly found species fills evolutionary gap between fish and land animals
EurekAlert (AAAS) ^ | 05 April 2006 | Staff

Paleontologists have discovered fossils of a species that provides the missing evolutionary link between fish and the first animals that walked out of water onto land about 375 million years ago. The newly found species, Tiktaalik roseae, has a skull, a neck, ribs and parts of the limbs that are similar to four-legged animals known as tetrapods, as well as fish-like features such as a primitive jaw, fins and scales.

These fossils, found on Ellesmere Island in Arctic Canada, are the most compelling examples yet of an animal that was at the cusp of the fish-tetrapod transition. The new find is described in two related research articles highlighted on the cover of the April 6, 2006, issue of Nature.

"Tiktaalik blurs the boundary between fish and land-living animal both in terms of its anatomy and its way of life," said Neil Shubin, professor and chairman of organismal biology at the University of Chicago and co-leader of the project.

Tiktaalik was a predator with sharp teeth, a crocodile-like head and a flattened body. The well-preserved skeletal material from several specimens, ranging from 4 to 9 feet long, enabled the researchers to study the mosaic pattern of evolutionary change in different parts of the skeleton as fish evolved into land animals.

The high quality of the fossils also allowed the team to examine the joint surfaces on many of the fin bones, concluding that the shoulder, elbow and wrist joints were capable of supporting the body-like limbed animals.

"Human comprehension of the history of life on Earth is taking a major leap forward," said H. Richard Lane, director of sedimentary geology and paleobiology at the National Science Foundation. "These exciting discoveries are providing fossil 'Rosetta Stones' for a deeper understanding of this evolutionary milestone--fish to land-roaming tetrapods."

One of the most important aspects of this discovery is the illumination of the fin-to-limb transition. In a second paper in the journal, the scientists describe in depth how the pectoral fin of the fish serves as the origin of the tetrapod limb.

Embedded in the fin of Tiktaalik are bones that compare to the upper arm, forearm and primitive parts of the hand of land-living animals.

"Most of the major joints of the fin are functional in this fish," Shubin said. "The shoulder, elbow and even parts of the wrist are already there and working in ways similar to the earliest land-living animals."

At the time that Tiktaalik lived, what is now the Canadian Arctic region was part of a landmass that straddled the equator. It had a subtropical climate, much like the Amazon basin today. The species lived in the small streams of this delta system. According to Shubin, the ecological setting in which these animals evolved provided an environment conducive to the transition to life on land.

"We knew that the rocks on Ellesmere Island offered a glimpse into the right time period and the right ancient environments to provide the potential for finding fossils documenting this important evolutionary transition," said Ted Daeschler of the Academy of Natural Sciences in Philadelphia, a co-leader of the project. "Finding the fossils within this remote, rugged terrain, however, required a lot of time and effort."

The nature of the deposits where the fossils were found and the skeletal structure of Tiktaalik suggests the animal lived in shallow water and perhaps even out of the water for short periods.

"The skeleton of Tiktaalik indicates that it could support its body under the force of gravity whether in very shallow water or on land," said Farish Jenkins, professor of organismic and evolutionary biology at Harvard University and co-author of the papers. "This represents a critical early phase in the evolution of all limbed animals, including humans--albeit a very ancient step."

The new fossils were collected during four summers of exploration in Canada's Nunavut Territory, 600 miles from the North Pole, by paleontologists from the Academy of Natural Sciences in Philadelphia, the University of Chicago and Harvard University. Although the team has amassed a diverse assemblage of fossil fish, Shubin said, the discovery of these transitional fossils in 2004 was a vindication of their persistence.

The scientists asked the Nunavut people to propose a formal scientific name for the new species. The Elders Council of Nunavut, the Inuit Qaujimajatuqangit, suggested "Tiktaalik" (tic-TAH-lick)--the word in the Inuktikuk language for "a large, shallow water fish."

The scientists worked through the Department of Culture, Language, Elders and Youth in Nunavut to collaborate with the local Inuit communities. All fossils are the property of the people of Nunavut and will be returned to Canada after they are studied.

The team depended on the maps of the Geological Survey of Canada. The researchers received permits from the Department of Culture, Language, Elders and Youth of the Government of Nunavut, and logistical support in the form of helicopters and bush planes from Polar Continental Shelf Project of Natural Resources Canada. The National Science Foundation and the National Geographic Society, along with an anonymous donor, also helped fund the project.

All thes scientists, natuarlists, and ministers had a opinion of origin of the species before Darwin and he gave credit for their work. He was not he first. Your opinion Sun, is void of knowledge.

Preface Origin of the Species: Charles Darwin

FIRST EDITION OF THIS WORK AN HISTORICAL SKETCH OF THE PROGRESS OF OPINION ON THE ORIGIN OF SPECIES PREVIOUSLY TO THE PUBLICATION OF THE FIRST EDITION OF THIS WORK
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. Passing over allusions to the subject in the classical writers,* the first author who in modern times has treated it in a scientific spirit was Buffon. But as his opinions fluctuated greatly at different periods, and as he does not enter on the causes * Aristotle, in his 'Physicae Auscultationes' (lib. 2, cap. 8, s. 2), after remarking that rain does not fall in order to make the corn grow, any more than it falls to spoil the farmer's corn when threshed out of doors, applies the same argument to organization: and adds (as translated by Mr Clair Grece, who first pointed out the passage to me), 'So what hinders the different parts [of the body] from having this merely accidental relation in nature? as the teeth, for example, grow by necessity, the front ones sharp, adapted for dividing, and the grinders flat, and serviceable for masticating the food; since they were not made for the sake of this, but it was the result of accident. And in like manner as to the other parts in which there appears to exist an adaptation to an end. Wheresoever, therefore, all things together (that is all the parts of one whole) happened like as if they were made for the sake of something, these were preserved, having been appropriately constituted by an internal spontaneity, and whatsoever things were not thus constituted, perished, and still perish. or means of the transformation of species, I need not here enter on details.

Lamarck was the first man whose conclusions on the subject excited much attention. This justly-celebrated naturalist first published his views in 1801; he much enlarged them in 1809 in his "Philosophie Zoologique,' and subsequently, in 1815, in the Introduction to his "Hist. Nat. des Animaux sans Vertébres.' In these works he upholds the doctrine that species, including man, are descended from other species. He first did the eminent service of arousing attention to the probability of all change in the organic, as well as in the inorganic world, being the result of law, and not of miraculous interposition. Lamarck seems to have been chiefly led to his conclusion on the gradual change of species, by the difficulty of distinguishing species and varieties, by the almost perfect gradation of forms in certain groups, and by the analogy of domestic productions. With respect to the means of modification, he attributed something to the direct action of the physical conditions of life, something to the crossing of already existing forms, and much to use and disuse, that is, to the effects of habit. To this latter agency he seemed to attribute all the beautiful adaptations in nature; — such as the long neck of the giraffe for browsing on the branches of trees. But he likewise believed in a law of progressive development; and as all the forms of life thus tend to progress, in order to account for the existence at the present day of simple productions, he maintains that such forms are now spontaneously generated.*

We here see the principle of natural selection shadowed forth, but how little Aristotle fully comprehended the principle, is shown by his remarks on the formation of the teeth. *I have taken the date of the first publication of Lamarck from Isid. Geoffroy Saint-Hilaire's ('Hist. Nat. Générale,' tom. ii. p. 405, 1859) excellent history of opinion on this subject. In this work a full account is given of Buffon's conclusions on the same subject. It is curious how largely my grandfather, Dr Erasmus Darwin, anticipated the views and erroneous grounds of opinion of Lamarck in his 'Zoonomia' (vol. i. pp. 500-510), published in 1794. According to Isid. Geoffroy there is no doubt that Goethe was an extreme partisan of similar views, as shown in the Introduction to a work written in 1794 and 1795, but not published till long afterwards: he has pointedly remarked ('Goethe als Naturforscher,' von Dr Karl Medinge s. 34) that the future question for naturalists will be how, for instance, cattle got their horns, and not for what they are used. It is rather a singular instance of the manner in which similar views arise at about the same time, that Goethe in Germany, Dr Darwin in England, and Geoffroy Saint-Hilaire (as we shall immediately see) in France; came to the same conclusion on the origin of species, in the years 1794-5.

Geoffroy Saint-Hilaire, as is stated in his 'Life,' written by his son, suspected, as early as 1795, that what we call species are various degenerations of the same type. It was not until 1828 that he published his conviction that the same forms have not been perpetuated since the origin of all things. Geoffroy seems to have relied chiefly on the conditions of life, or the 'monde ambiant' as the cause of change. He was cautious in drawing conclusions, and did not believe that existing species are now undergoing modification; and, as his son adds, "C'est donc un problème à réserver entièrement à l'avenir, supposé meme que l'avenir doive avoir prise sur lui.'

In 1813, Dr W. C. Wells read before the Royal Society 'An Account of a White female, part of whose skin resembled that of a Negro'; but his paper was not published until his famous 'Two Essays upon Dew and Single Vision' appeared in 1818. In this paper he distinctly recognises the principle of natural selection, and this is the first recognition which has been indicated; but he applies it only to the races of man, and to certain characters alone. After remarking that negroes and mulattoes enjoy an immunity from certain tropical diseases, he observes, firstly, that all animals tend to vary in some degree, and, secondly, that agriculturists improve their domesticated animals by selection; and then, he adds, but what is done in this latter case 'by art, seems to be done with equal efficacy, though more slowly, by nature, in the formation of varieties of mankind, fitted for the country which they inhabit. Of the accidental varieties of man, which would occur among the first few and scattered inhabitants of the middle regions of Africa, some one would be better fitted than the others to bear the diseases of the country. This race would consequently multiply, while the others would decrease; not only from their inability to sustain the attacks of disease, but from their incapacity of contending with their more vigorous neighbours. The colour of this vigorous race I take for granted, from what has been already said, would be dark. But the same disposition to form varieties still existing, a darker and a darker race would in the course of time occur: and as the darkest would be the best fitted for the climate, this would at length become the most prevalent; if not the only race, in the particular country in which it had originated.' He then extends these same views to the white inhabitants of colder climates. I am indebted to Mr Rowley, of the United States, for having called my attention, through Mr Brace, to the above passage in Dr Wells' work.

The Hon. and Rev. W. Herbert, afterwards Dean of Manchester, in the fourth volume of the 'Horticultural Transactions,' 1822, and in his work on the 'Amaryllidaceae' (1837, pp. 19, 339), declares that 'horticultural experiments have established, beyond the possibility of refutation, that botanical species are only a higher and more permanent class of varieties.' He extends the same view to animals. The Dean believes that single species of each genus were created in an originally highly plastic condition, and that these have produced, chiefly by intercrossing, but likewise by variation, all our existing species.

In 1826 Professor Grant, in the concluding paragraph in his well-known paper ('Edinburgh philosophical journal,' vol. xiv. p. 283) on the Spongilla, clearly declares his belief that species are descended from other species, and that they become improved in the course of modification. This same view was given in his 55th Lecture, published in the 'Lancet' in 1834.

In 1831 Mr Patrick Matthew published his work on 'Naval Timber and Arboriculture,' in which he gives precisely the same view on the origin of species as that (presently to be alluded to) propounded by Mr Wallace and myself in the 'Linnean journal,' and as that enlarged in the present volume. Unfortunately the view was given by Mr Matthew very briefly in scattered passages in an Appendix to a work on a different subject, so that it remained unnoticed until Mr Matthew himself drew attention to it in the 'Gardener's Chronicle,' on April 7th, 1860. The differences of Mr Matthew's view from mine are not of much importance; he seems to consider that the world was nearly depopulated at successive periods, and then re-stocked; and he gives as an alternative, that new forms may be generated ' without the presence of any mould or germ of former aggregates.' I am not sure that I understand some passages; but it seems that he attributes much influence to the direct action of the conditions of life. He clearly saw, however, the full force of the principle of natural selection.

The celebrated geologist and naturalist, Von Buch, in his excellent 'Description physique des Isles Canaries' (1836, p. 147), clearly expresses his belief that varieties slowly become changed into permanent species, which are no longer capable of intercrossing.

Rafinesque, in his 'New Flora of North America,' published in 1836, wrote (p. 6) as follows:- 'All species might have been varieties once, and many varieties are gradually becoming species by assuming constant and peculiar characters'; but farther on (p. 18) he adds, 'except the original types or ancestors of the genus.'

In 1843-44 Professor Haldeman ('Boston journal of Nat. Hist. U. States, vol. iv. p. 468) has ably given the arguments for and against the hypothesis of the development and modification of species: he seems to lean towards the side of change.

The 'Vestiges of Creation' appeared in 1844. In the tenth and much improved edition (1853) the anonymous author says (p. 155):- 'The proposition determined on after much consideration is, that the several series of animated beings, from the simplest and oldest up to the highest and most recent, are, under the providence of God, the results, first, of an impulse which has been imparted to the forms of life, advancing them, in definite times, by generation, through grades of organisation terminating in the highest dicotyledons- and vertebrata, these grades being few in number, and generally marked by intervals of organic character, which we find to be a practical difficulty in ascertaining affinities; second, of another impulse connected with the vital forces, tending, in the course of generations, to modify organic structures in accordance with external circumstances, as food, the nature of the habitat, and the meteoric agencies, these being the ''adaptations'' of the natural theologian.' The author apparently believes that organisation progresses by sudden leaps, but that the effects produced by the conditions of life are gradual. He argues with much force on general grounds that species are not immutable productions. But I cannot see how the two supposed 'impulses' account in a scientific sense for the numerous and beautiful co-adaptations which we see throughout nature; I cannot see that we thus gain any insight how, for instance, a woodpecker has become adapted to its peculiar habits of Life. The work, from its powerful and brilliant style, though displaying in the earlier editions little accurate knowledge and a great want of scientific caution, immediately had a very wide circulation. In my opinion it has done excellent service in this country in calling attention to the subject, in removing prejudice, and in thus preparing the ground for the reception of analogous views.

In 1846 the veteran geologist N. J. d'Omalius d'Halloy published in an excellent though short paper ("Bulletins de l'Acad. Roy Bruxelles,' tom. xiii. p. 581) his opinion that it is more probable that new species have been produced by descent with modification than that they have been separately created: the author first promulgated this opinion in 1831.

Professor Owen, in 1849 ('Nature of Limbs,' p. 86), wrote as follows:- "The archetypal idea was manifested in the flesh under diverse such modifications, upon this planet, long prior to the existence of those animal species that actually exemplify it. To what natural laws or secondary causes the orderly succession and progression of such organic phenomena may have been committed, we, as yet, are ignorant.' In his Address to the British Association, in 1858, he speaks (p. li.) of "the axiom of the continuous operation of creative power, or of the ordained becoming of living things.' Farther on (p. xc.), after referring to geographical distribution, he adds, 'These phenomena shake our confidence in the conclusion that the Apteryx of New Zealand and the Red Grouse of England were distinct creations in and for those islands respectively. Always, also, it may be well to bear in mind that by the word ''creation'' the zoologist means '"a process he knows not what.'' He amplifies this idea by adding that when such cases as that of the Red Grouse are enumerated by the zoologists as evidence of distinct creation of the bird in and for such islands, he chiefly expresses that he knows not how the Red Grouse came to be there, and there exclusively; signifying also, by this mode of expressing such ignorance, his belief that both the bird and the islands owed their origin to a great first Creative Cause.' If we interpret these sentences given in the same Address, one by the other, it appears that this eminent philosopher felt in 1858 his confidence shaken that the Apteryx and the Red Grouse first appeared in their respective homes, 'he knew not how,' or by some process 'he knew not what.'

This Address was delivered after the papers by Mr Wallace and myself on the Origin of Species, presently to be referred to, had been read before the Linnean Society. When the first edition of this work was published, I was so completely deceived, as were many others, by such expressions as 'the continuous operation of creative power,' that I included Professor Owen with other palaeontologists as being firmly convinced of the immutability of species; but it appears ('Anat. of Vertebrates,' vol. iii. p. 796) that this was on my part a preposterous error. In the last edition of this work I inferred, and the inference still seems to me perfectly just, from a passage beginning with the words 'no doubt the type-form,' &c. (Ibid. vol. i. p. xxxv.), that Professor Owen admitted that natural selection may have done something in the formation of a new species; but this it appears (Ibid. vol. nl. p. 798) is inaccurate and without evidence. I also gave some extracts from a correspondence between Professor Owen and the Editor of the 'London Review,' from which it appeared manifest to the Editor as well as to myself, that Professor Owen claimed to have promulgated the theory of natural selection before I had done so; and I expressed my surprise and satisfaction at this announcement; but as far as it is possible to understand certain recently published passages (Ibid. vol. iii. p. 798) I have either partially or wholly again fallen into error. It is consolatory to me that others find Professor Owen's controversial writings as difficult to understand and to reconcile with each other, as I do. As far as the mere enunciation of the principle of natural selection is concerned, it is quite immaterial whether or not Professor Owen preceded me, for both of us, as shown in this historical sketch, were long ago preceded by Dr Wells and Mr Matthews.

M. Isidore Geoffroy Saint-Hilaire, in his lectures delivered in 1850 (of which a Résumé appeared in the 'Revue et Nag. de Zoolog.,' Jan. 1851), briefly gives his reason for believing that specific characters "sont fixés, pour chaque espèce, tant qu'elle se perpétue au milieu des mèmes circonstances: ils se modifient, si les circonstances ambiantes viennent à changer.' 'En résumé, l'observation des animaux sauvages démontre déjà la variabilité limité des espèces. Les expériences sur les animaux sauvages devenus domestiques, et sur les animaux domestiques redevenus sauvages, la démontrent plus clairement encore. Ces memes expériences prouvent, de plus, que les différences produites peuvent etre de valeur générique.' In his 'Hist. Nat. Généralé (tom. ii. p. 430, 1859) he amplifies analogous conclusions.

From a circular lately issued it appears that Dr Freke, in 1851 ("Dublin Medical Press,' p. 322), propounded the doctrine that all organic beings have descended from one primordial form. His grounds of belief and treatment of the subject are wholly different from mine; but as Dr Freke has now (1861) published his Essay on the 'Origin of Species by means of Organic Affinity,' the difficult attempt to give any idea of his views would be superfluous on my part.

Mr Herbert Spencer, in an Essay (originally published in the 'Leader,' March, 1852, and republished in his 'Essays,' in 1858), has contrasted the theories of the Creation and the Development of organic beings with remarkable skill and force. He argues from the analogy of domestic productions, from the changes which the embryos of many species undergo, from the difficulty of distinguishing species and varieties, and from the principle of general gradation, that species have been modified; and he attributes the modification to the change of circumstances. The author (1855) has also treated psychology on the principle of the necessary acquirement of each mental power and capacity by gradation.

In 1852 M. Naudin, a distinguished botanist, expressly stated, in an admirable paper on the Origin of Species ('Revue Horticole, p. 102; since partly republished in the 'Nouvelles Archives du Muséum,' tom. i. p. 171), his belief that species are formed in an analogous manner as varieties are under cultivation; and the latter process he attributes to man's power of selection. But he does not show how selection acts under nature. He believes, like Dean Herbert, that species, when nascent, were more plastic than at present. He lays weight on what he calls the principle of finality, 'puissance mystérieuse, indéterminée; fatalité pour les uns; pour les autres volonté providentielle, dont l'action incessante sur les ètres vivants détermine, à toutes les époques de l'existence du monde, la forme, le volume, et la durée de chacun d'eux, en raison de sa destinée dans l'ordre de choses dont il fait partie. C'est cette puissance qui harmonise chaque membre à l'ensemble, en l'appropriant à la fonction qu'il doit remplir dans l'organisme général de la nature, fonction qui est pour lui sa raison d'ètre.'*

* From references in Bronn's 'Untersuchungen über die Entwickenlungs-Gesetze,' it appears that the celebrated botanist and palaeontologist Unger published, in 1852, his belief that species undergo development and modification. Dalton, likewise, in Pander and Dalton's work on Fossil Sloths, expressed, in 1821 a similar belief. Similar views have, as is well known, been maintained by Oken in his mystical 'Natur-philosophie.' From other references in Godron's work 'Sur l'Espéce,' it seems that Bory St Vincent, Burdach, Poiret, and Fries, have all admitted that new species are continually being produced.

In 1853 a celebrated geologist, Count Keyserling ("Bulletin de la Soc. Gèolog.,' 2nd Ser., tom. x. p. 357), suggested that as new diseases, supposed to have been caused by some miasma, have arisen and spread over the world, so at certain periods the germs of existing species may have been chemically affected by circumambient molecules of a particular nature, and thus have given rise to new forms.

In this same year, 1853, Dr Schaaffhausen published an excellent pamphlet ('Verhand. des Naturhist. Vereins der preuss. Rheinlands,' &c.), in which he maintains the development of organic forms on the earth. He infers that many species have kept true for long periods, whereas a few have become modified. The distinction of species he explains by the destruction of intermediate graduated forms. 'Thus living plants and animals are not separated from the extinct by new creations, but are to be regarded as their descendants through continued reproduction.'

I may add, that of the thirty-four authors named in this Historical Sketch, who believe in the modification of species, or at least disbelieve in separate acts of creation, twenty-seven have written on special branches of natural history or geology.

A well-known French botanist, M. Lecoq, writes in 1854 ('Etudes sur Géograph. Bot.,' tom. i. p. 250), 'On voit que nos recherches sur la fixité ou la variation de l'espèce, nous conduisent directement aux idées émises, par deux hommes justement célèbres, Geoffroy Saint-Hilaire et Goethe.' Some other passages scattered through M. Lecoq's large work, make it a little doubtful how far he extends his views on the modification of species.

The 'Philosophy of Creation' has been treated in a masterly manner by the Rev. Baden Powell, in his "Essays on the Unity of Worlds,' 1855. Nothing can be more striking than the manner in which he shows that the introduction of new species is "a regular, not a casual phenomenon,' or, as Sir John Herschel expresses it, 'a natural in contradistinction to a miraculous, process.'

The third volume of the "Journal of the Linnean Society' contains papers, read July 1st, 1858, by Mr Wallace and myself, in which, as stated in the introductory remarks to this volume, the theory of Natural Selection is promulgated by Mr Wallace with admirable force and clearness.

Von Baer, towards whom all zoologists feel so profound a respect, expressed about the year 1859 (see Prof. Rudolph Wagner, a "Zoologisch-Anthropologische Untersuchungen,' 1861, s. 51) his conviction, chiefly grounded on the laws of geographical distribution, that forms now perfectly distinct have descended from a single parent-form.

In June, 1859, Professor Huxley gave a lecture before the Royal Institution on the 'Persistent Types of Animal Life.' Referring to such cases, he remarks, "It is difficult to comprehend the meaning of such facts as these, if we suppose that each species of animal and plant, or each great type of organisation, was formed and placed upon the surface of the globe at long intervals by a distinct act of creative power; and it is well to recollect that such an assumption is as unsupported by tradition or revelation as it is opposed to the general analogy of nature. If, on the other hand, we view 'Persistent Types' in relation to that hypothesis which supposes the species living at any time to be the result of the gradual modification of pre-existing species a hypothesis which, though unproven, and sadly damaged by some of its supporters, is yet the only one to which physiology lends any countenance; their existence would seem to show that the amount of modification which living beings have undergone during geological time is but very small in relation to the whole series of changes which they have suffered.'

In December, 1859, Dr Hooker published his 'Introduction to the Australian Flora.' In the first part of this great work he admits the truth of the descent and modification of species, and supports this doctrine by many original observations.

The first edition of this work was published on November 24th, 1859, and the second edition on January 7th, 1860.

ID IS a scientific theory, and many scientists have said so (even IF it's true that Behe did not).

ID is not a scientific theory. A court of law has ruled it it is not. 99+% of scientists say it is not. Some of it's leading proponents admit it is not unless the definition of science is changed, which means they admit it is not a scientific theory. To date it meets none of the criteria a scientific theory must meet - ID is not testable, it is not falsifiable, and it has no predictive value.

You repeating it is a scientific theory over and over again doesn't make it true. And what a handful of disingenuous religiously motivated scientists say won't make it true either. Until ID meets the criteria that a scientific theory must meet it is useless other than as a philosophical/theological idea.

Wishful thinking that at some time in the future ID will become an accepted scientific theory is based on nothing but fantasy. If ID still cannot be tested, cannot be falsified, and cannot predict anything 10, 20, or 50 years from now, it will remain what it is, useless.

>>>Archeopteryx IS a transitional.<<<

No, there is more and more scientists who disagree that it is.

More are just saying it is a funky part of nature, like the Platypus.

>>>Wrong on all accounts.<<<

Yea, I know Behe is wrong. :rolleyes:

>>>>Historical sciences are as valid as any other branch of science.<<<<

No, Origin Sciences is based upon your Philosophical Presuppositions, because it can not be observed. You can not breed a fruit fly today and tomorrow get a cricket. Rather you have to infer one can evolve into the other based upon....here it comes....your presuppositions that Evolution and Naturalism are true.

Even worse is that Material Monism is irrational in the most basic, and scientists don't even bother to try to address it, because they know that Kalam Cosmological theory and basic rationalism on Matter and the universe not being eternal, Material Monism falls apart. It is why Hawkings tried to get a TV>FV Eternality in order to get around the boulder in the road.

Even most Evolutionary Scientists will reject Creationism, not on facts, but on the presupposition, they say, "Science can only be concerned with what is observable and testable, and can not have beliefs based upon 'faith'".

Ironically, they have blind faith in Material Monism with out justifying the rationality. Rather they try to "shift the burden of proof" and tell the Creationists they need to "Prove God First", but this is a rejection of rationalism. Rationalism requires both to prove their position.

Because the most basic of the Material Monist worldview is irrational, Atheists have:

1) Rejected Rationalism (Modernism and Post-Modernism) in order to justify their beliefs in Materialism, yet hold to rationalism in Science, which is contadictory
2) Keep to Rationalism without proving any basic priori, but maintain the priori of empiricism.

The fact is that Science has no right to talk about anything Philosophical, they claim this philosophical position, but are unable to rationally justify it and have repeated it enough that most non-philosophers buy it hook line and sinker.

Well, do you really want to appeal to something irrational?

You are appealling ad populum, which is a logical fallacy.

Ironic that Science is rejecting reason, when they claim Theism can't be rational. (Theism is Rational, it is Material Monism that is irrational in the most basic). Science appeals to empiricism, which isn't reason.

Just because most scientists reject something, doesn't mean that they are right. A great example is that for most of recorded history it was accepted by scientists that the atom was unsplitable. Guess what? 99%+ were wrong.

>>>You repeating it is a scientific theory over and over again doesn't make it true. And what a handful of disingenuous religiously motivated scientists say won't make it true either. Until ID meets the criteria that a scientific theory must meet it is useless other than as a philosophical/theological idea.<<<

The problem is that science refuses to justify it's priori of Naturalism in the most basic. Science assumes it. First anything from Theism to Biology must have it's worldview rational otherwise it is basing it's conclusions on faulty foundation.

>>>Wishful thinking that at some time in the future ID will become an accepted scientific theory is based on nothing but fantasy. If ID still cannot be tested, cannot be falsified, and cannot predict anything 10, 20, or 50 years from now, it will remain what it is, useless.<<<

I doubt that. The tide has turned. If there was no threat Material Monist Scientists wouldn't be fighting so hard against allowing it into the peer journals. Rather, they would just allow it and then next month ridicule it. Scientists can't afford that, because ID would put more holes into Evolution than rationalism does Material Monism.

"No, there is more and more scientists who disagree that it is."

Feducia is in a very small minority. The vast majority consider it transitional.

"More are just saying it is a funky part of nature, like the Platypus."

Nonsense.

"Yea, I know Behe is wrong."

Behe IS wrong, though that isn't what I was talking about when I said *Wrong on all accounts*. I was talking about your statement:

"They want to claim missing links such as in a "Punctured Equilibrium" fashion, but admit that "Punctured Equilibrium" can't occur without:

A)Intelligent Design
B)Discounting everything we know about Micro-Biology "

Unless these are Behe's words and not yours and you just forgot to attribute it to him. The above is, as I said, wrong on all accounts. PE doesn't need ID, and it doesn't go against anything known about microbiology.

"No, Origin Sciences is based upon your Philosophical Presuppositions, because it can not be observed."

No, it's based on the same type of evidence gathering as other sciences. A great many events in science are not directly observed. Nobody has ever seen an atom directly. Historical sciences, like geology, use the same methods of finding physical evidence and testing that evidence as other sciences. If historical sciences were just a fairy tale, then there would be no way to do forensic studies of a murder. In fact, forensic evidence is considered much more reliable than eyewitness accounts.

"You can not breed a fruit fly today and tomorrow get a cricket."

If we did it would falsify the theory of evolution. You obviously are arguing against a theory you don't even understand.

"Rather you have to infer one can evolve into the other based upon....here it comes....your presuppositions that Evolution and Naturalism are true."

Actually, nobody thinks you can evolve a fly into a cricket. That being said, scientists conclude that populations of organisms evolve based on multiple lines of evidence (including direct observation of speciation)in many different fields that are cross checked and verified by continued observations and experimentation.

"Even most Evolutionary Scientists will reject Creationism, not on facts, but on the presupposition, they say, "Science can only be concerned with what is observable and testable, and can not have beliefs based upon 'faith'"."

And the scientists are correct. God isn't testable or observable. Faith is for theology.

"Ironically, they have blind faith in Material Monism with out justifying the rationality. Rather they try to "shift the burden of proof" and tell the Creationists they need to "Prove God First", but this is a rejection of rationalism."

Scientists don't ask for *proof*, at all. They ask for evidence. There is a difference. It is not possible to prove God using science. It is not possible to prove ANYTHING using science. It is however possible to test certain things using science, and to come to a reasonable degree of confidence in our conclusions. It is simply not possible to test for God.

BTW, scientists are not *Material Monists*; they do not say that the physical is all there is. They say that the physical and testable are all that science is capable of examining. If there are other states of existence, they are outside the ability of science to make a claim one way or the other. This is called methodological naturalism, not material monism.

"Because the most basic of the Material Monist worldview is irrational, Atheists have:"

Atheism has nothing to do with evolution. Evolution, like every theory in science, is incapable of saying anything pro or con about the existence of a God.

"The fact is that Science has no right to talk about anything Philosophical, they claim this philosophical position, but are unable to rationally justify it and have repeated it enough that most non-philosophers buy it hook line and sinker."

That's why science is agnostic about God, not atheistic.

And this has nothing to do with evolution.

You are appealling ad populum, which is a logical fallacy. ... Just because most scientists reject something, doesn't mean that they are right.

One of the things a scientific theory must do is convince most other scientists it is valid, so the views of 99+% of scientists are valid. This is not a logical fallacy.

A great example is that for most of recorded history it was accepted by scientists that the atom was unsplitable. Guess what? 99%+ were wrong.

Modern science is only few hundred years old. So your 'recorded history' comment is irrelevant. Modern atomic theory, the only truly scientific theory about the atom is only a bit over 100 years old. If it's what you claim, I'd like to see a citation for you're statement that 99+% of scientists claimed that the atom could not be split since the introduction of modern atomic theory.

The problem is that science refuses to justify it's priori of Naturalism in the most basic. Science assumes it. First anything from Theism to Biology must have it's worldview rational otherwise it is basing it's conclusions on faulty foundation.

The justification for, and validation of, modern science is the modern world you live in. The marvels of our modern world are the products of science. Your statements are just meaningless philosophical musings that have no bearing on the reality produced through the application of scientific theories. What future marvels might we expect from ID? Let your imagination roam free and just give me one example.

The 'Philosophy of Creation' has been treated in a masterly manner by the Rev. Baden Powell, in his "Essays on the Unity of Worlds,' 1855. Nothing can be more striking than the manner in which he shows that the introduction of new species is "a regular, not a casual phenomenon,' or, as Sir John Herschel expresses it, 'a natural in contradistinction to a miraculous, process.'

This is the father of the founder of the Boy Scouts. A reverend and a Darwinist.

The fact is that Science has no right to talk about anything Philosophical...

Is the converse true? Does religious belief give one the right to address scientific matters?

The Baden-Powell who founded the scouts (and was a Boer War hero of the Siege of Mafeking) is the son of the creationist author.

Baden-Powell, Chief Scout of the World.

Pinetree is a very confusing website. I had to struggle a bit before posting, because it seems there are about 200 Baden-Powells.

Could you please provide a list of rejected articles, along with the peer-reviewed reasons for the rejection?

I wouldn't worry about it. But having found this nugget, I'm going to ask the next evolutionisthefatherofnazism creationist to explain the fact that a Darwinist produced the founder of the Boy Scouts.

I have been rather busy with a mom and dad in the hospital... car accident...

So, where were we...

I accepted Evolution when I accepted change? NO, I did not. Change is not evolution.
