Author | Topic: TOE and the Reasons for Doubt | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Peg Member (Idle past 4952 days) Posts: 2703 From: melbourne, australia Joined: |
We hear all the reasons why evolution is a 'fact' and all the 'evidence' which is supposed to make us feel compelled to believe it. Well this topic is not about reasons TO BELIEVE, but rather the DOUBTS THAT EXIST among those who study ToE.
I dedicate this to Melindoor to whom I made the suggestion to seriously consider some of these doubts. No.1 Doubt the fossil record. Darwin’s theory has always been closely linked to evidence from fossils yet do they show the gradual changes that he predicted ? quote: Doubt No.2 Evolution by Mutation Many scientists have noted that over time, the descendants of living things may change slightly. Charles Darwin called this process descent with subsequent modification. Such changes have been observed directly, recorded in experiments, and used ingeniously by plant and animal breeders. Seems plausible on the surface. what is the evidence for mutations in evolution?
quote: Doubt No.3 Evolution by Naturual selection Darwin believed that natural selection would favor those life-forms best suited to the environment, while less suitable life-forms would eventually die off. Modern evolutionists teach that isolated groups eventually developed into totally new species. The finch's on the golapogolas islands was given as evidence of this. The finch's with smaller beaks died out and those with larger beaks survived during a drought. Seems plausible doesnt it. did the finch's on the golapogolas islands prove that natural selection drives evolution? No they didnt. In the years following the drought, finches with smaller beaks again dominated the population. Thus, Peter Grant and graduate student Lisle Gibbs wrote in the science journal Nature in 1987 that they had seen a reversal in the direction of selection. In 1991, Grant wrote that the population, subjected to natural selection, is oscillating back and forth each time the climate changes. The researchers also noticed that some of the different species of finches were interbreeding and producing offspring that survived better than the parents. So even after all the small beaked finchs had died out, years later, they were back again...what does this show? Evolutionary theorist Jeffrey Schwartz wrote in 1999 that "natural selection may be helping species to adapt to the changing demands of existence, but it is not creating anything new. _____________________________________________________________ Now i havnt even gone into the 'origin' of life debate which, according to science, is highly unlikely. I'll be happy to add this later...the chance of life spontaneously generating is unbelievably improbably...so much so we could say it is impossible. I hope this is good for a start and hopefully will get you thinking that there is enough doubt in the ToE, to not completly write off the idea of a creator. (im not sure which thread, i'll let the mods decide) Edited by Peg, : No reason given. Edited by Adminnemooseus, : Fix a bit of coding.

Hi Melindoor
Melindoor writes: Of course animals and plants reproduce according to their species!! Otherwise they wouldn't be species! Evolution doesn't say that a dog will give birth to a cat, or any other creature but a dog. im aware of that, but the point is that evolution is said to explain how the great variety of species developed, albeit slowly, and yet the fossil record does not show the supposed changes taking place. It shows fully formed and functioning creatures as opposed to anything in its development stage.
quote: Melindoor writes: I'm also confused about this alleged lack of transitional fossils. Why don't the following qualify as transitional?Archaeopteryx Eohippus regarding the Archaeopteryx, the fossil has perfectly formed feathers and wings that are capable of flight. Also the wing and leg bones are thin and hollow which is what is found in birds today. It does not predate birds, because fossils of other birds have been found in rocks of the same period as Archaeopteryx. The New Evolutionary Timetable says that the fossils show very little evidence for evolutionary modification so obviously not all are in agreement that the fossil document the full history of the horse family. Some even think that the animal is still alive today...the fossil is apparently very similar to a fox like animal called a Hyrax in Africa. and i dont know about your 3rd example.
Meldinoor writes: Darwin wrote those words over a century ago. It is a fact that many new "transitional" fossils have been uncovered since then, and our knowledge of the fossil record has been greatly expanded. they claim to have found transitional fossils, true. In Darwins day he wrote in Ori/Spec There is another and allied difficulty, which is much more serious. I allude to the manner in which species belonging to several of the main divisions of the animal kingdom suddenly appear in the lowest known fossiliferous rocks. ... The case at present must remain inexplicable; and may be truly urged as a valid argument against the [evolutionary] views here entertained" And after a century of digging and millions of catelogued fossils, what have they got? the Swedish botanist Heribert Nilsson has spent over 40 years in the research field and he wrote in his book 'The Synthetic Origin of the Species' 1953 p.1212"It is not even possible to make a caricature of an evolution out of palaeobiological facts. The fossil material is now so complete that the lack of transitional series cannot be explained as due to the scarcity of material. The deficiencies are real, they will never be filled." Granted that this was written in the 50's, but surely with thousands of scientists collecting fossils from all around the globe, they would have found many transitional fossils. Meldinoor writes: I know my description may have been a bit tricky to follow, and I haven't figured out how to include pictures in my posts, but I'll direct you to the wikipedia article on ring species to find out more. i dont have a problem with this example, its not in contention. The salamanders are still salamanders, perhaps a different type of salamander, but a salamander nonetheless. I dont doubt that Genetics play a part in the diversity of species. That wiki article doesnt say anything about mutation. Mutations supposedly involved in evolution are small accidental changes that accumulate over a long period of time...im not sure these fish qualify, if they do, i dont see how.
Meldinoor writes: How does this disprove evolution?! All it is is an example of an occassion where no new traits have arisen. What are we supposed to be expecting? Finches with antlers? Finches who evolve electro-sensitivity? I don't follow the argument unless it shows how evolution would predict something that we are not seeing in the finch population. I used 'Darwins finch's' as an example because they were said to be a compelling example of speciation [the evolution of new species] but the fact that the population, subjected to natural selection, is oscillating back and forth each time the climate changes seem to be more better explained as the maintenance of adaptation. Whole populations of small beaked finshes died out, yet they came back again decades later! Think about it, the finches didnt go thru an evolutionary change. It wasnt speciation...it was adaption and because the small beaked finches began to be born again, it must have been the genes that was controlling the change, not natural selection or speciation or evolution. The finches did not change to a new species of finch.
Meldinoor writes: I never wrote off the idea of a creator. Nor does evolution necessitate the absence of one. thats not entirely true We could not have been created if we evolved. Its one or the other.

Huntard writes: So, you accept evolution? You're confusing me. the salamanders interbred to much that the genes become narrowed down so much that these ones could no longer breed with the other ones i believe this is more about genetics then evolution, but if you want to call it evolution then go ahead. The salamanders are still salamanders. donkeys horses and mules are another example of how two of the species can breed to a point but no further. They are all still equine though.
Huntard writes: Really? God could not have guided evolution? So, he's not omnipotent? no, because he's a God of Order, not of disorder. If he wasnt involved the creation of the great variety of species on earth, then he cant lay claim to being the creator of them. Yet he does lay claim to being the creator of them. So either he did create them, or he didnt. its one or the other.

greyseal writes: What it IS is a slow progression from one form to another, via what you would happily call "microevolution" until what we call "speciation" occurs (and yes, people with greater knowledge than me may well disagree on some points and the definition, but I think for this level, it's broadly true) the teaching of macroevolution is built upon the claim that mutations can produce not only new species but also entirely new families of plants and animals. But what has more then 50 years of research and experimentation with mutatins produced? Are you aware that since the 30's biologists in general and geneticists and breeders in particular, tried inducing and selecting favorable mutations to attempt to produce new and better plants and animals? Around the world they have put millions into research programs, using methods that promised to speed up evolution. after more than 40 years of intensive research, Peter von Sengbusch, one researcher said that the attempt to cultivate increasingly productive varieties by irradiation, widely proved to be a failure. By the 1980’s, most scientists had abandoned mutation breeding in Western countries because it simply failed. Almost all the mutants they produced died or were weaker than wild varieties. Wolf-Ekkehard Lnnig, a german scientist from the Max Planck Institute said
quote: Think about that for moment. If even highly trained scientists cannot produce new species by artificially inducing and selecting favorable mutations, is it likely that an unintelligent process would do a better job?
greyseal writes: darwin's finches "oscillating back and forth" - uh, so? Not a problem, really it isn't. if the finches really did develop into a new species, as the theory suggests, then why should they return to what they were? it means the species never changed...it was the same species only with different traits. therefore it is a problem for evolution by natural selection.
greyseal writes: Of course, it does negate the bible as a literal account, but we all know you don't think it's a literal account either. i certainly do believe it is a literal account. God created each species directly, thats my literal understanding. He didnt leave it all to chance, he didnt start the ball rolling then let it all go its own wild way. No, "According to their Kinds, he created them" Edited by Peg, : No reason given. Edited by Peg, : No reason given.

Percy writes: If you find a quote from an evolutionary scientist who appears to be rejecting evolution in some way, you should assume he was taken out of context until proven otherwise. the point of Sagans quote was to show that he was acknowledging that the fossil record shows great design. The design in living things could not have come about by random mutations...the emphasis is on his description of a 'design' in nature how can we look at the evidence of design, then say its all a result of slow random mutation that makes no sense. Its contrary to the evidence that we see.

DrAdequate writes: Except that he explicitly says that the fossil record is "inconsistent with an efficient designer". To pretend that he was trying to make any other point is dishonest. I wasnt trying to pretend anything. He is clearly saying that he sees 'design' in nature. Isnt that what ID proponents say too? There is design in nature and therefore there must be a designer?? and why does he say that? It is likely because he is biased towards evolution rather then design...even though he acknowleges 'design' in living things. I can see that he is trying to say that the evidence for evolution does not imply a designed species, but thats exactly what the ToE is...its about slow undirected change as opposed to purposful design. He's using evolution to say that life shows something that has come from trial and error because he is interpreting things with evolution as the basis.

Meldinoor writes: Aside from the fact that this doesn't make sense. How do you reconcile an old-earth belief with this belief that animals narrow down their genes? If an animal's DNA degenerated within an observable time period, how come there are still functional animals left today, after millions of years? i think its called genetics distinctive traits are due to isolation of groups for long periods of time...we see it in the human population and we see it in animals. im doing a darwin and giving a theory without evidence here...im sure the salamander population was interbreeding...its genetics.

Percy writes: How can you read this passage and conclude, "The point of Sagan's quote was to show that he was acknowledging that the fossil record shows great design. now your being daft that was my reason for using the quote. it was to highlight that he aknowledged the design in nature even though he said the notion of design was disconcerting.
Percy writes: And if you're sure you have the correct quote, as is the case here with this Sagan quote, and you still think it denies evolution i didnt say he denied evolution, i said he he acknowledged design.

greyseal writes: Your quote-mine of Sagan fails on points a) and b) because it wasn't in context and (being unfairly snipped to change it's meaning) wasn't reliable. if he didnt think there was design in nature, why say "The fossil evidence could be consistent with the idea of a great designer" to me thats an acknowlegement of design even if he does believe in evolution.

DrAdequate writes: It also has gastralia, teeth, independent digits, no synsacrum, a pelvis unfused to its vertebrae, and no pygostyle. Putting it all together together, we find that it is an intermediate between feathered dinosaurs and modern birds. Is it?Reptiles are cold-blooded and heavy/solid, whereas birds are warm-blooded and very light. Flight depends on several factors being present at one time and Archaeopteryx already had fully developed wings with featheres (no scales), and had special feet equipped for perching. Its bone structure has also been seen to be similar to modern birds. So to tag it as a reptile doesnt seem reasonable. DrAdequate writes: That would be why no-one ever claimed that they did. Really? no one ever claimed Darwin's finches as evidence of speciation? except for a brochure published in 1999 by the National Academy of SciencesA particularly compelling example of speciation [the evolution of new species] involves the 13 species of finches studied by Darwin on the Galpagos Islands, now known as Darwin’s finches. the article specifically calls darwins finches an example of speciation.

mikethewiz writes: you're correct because even if you do quote-mine, if someone clearly says something in a quote which is clear, then it's a diversionary tactic, to say, "you quote-mined". good point mike that is probably why many evolutionists will qualify their statements about the 'd' with a confirmation of their firm belief in evolution they might be in fear of falling out with the fraternity...or worse...being branded a creationist! lol David Attenborough likes to talk about how clever evolution is.

Meldinoor writes: No, it's not called Genetics. Genetics is a field. I'm looking for the name of the phenomena you describe where animal DNA degenerates or "narrows" down over time. i said i was 'doing a darwin' you know, providing a theory without evidence lol Tell me this, Can you have children with your any of your close family relations, and not expect defects of one sore or another?

mrjack writes: Australopithecus, the list goes on and on. i wouldnt put australopithecus as a transitional link either. It has a skull that differs from humans with a much smaller brain capacitySome say that its skull is simiannot human. They are more like liviing living monkeys and apes then us. and that goes for Lucy too. Robert Jastrow in the 1981 book The Enchanted Loom: Mind in the Unverse, says: This brain was not large in absolute size; it was a third the size of a human brain. even New Scientist said that Lucys skull was very similar to a chimpanzees.

greyseal writes: Even when it gets pointed out to you that the quote deliberately and incorrectly makes it appear as if (insert name of famous person here) holds a different viewpoint than they do, you cling to that quote like a limpet to rock. i put that initial quote there in my msg 13 the quote of sagan reveals that he sees design even though he doesnt believe in a designer...perhaps i should have made it clear in msg 13 about the intent of using his quote so for that i apologise.
