Author | Topic: Empirical Evidence for Evolution | |||||||||||||||||||||||||||
John Paul Inactive Member |
Yes joz, limits as we observe in nature. Those would be the limits of a body builder; the limits of a runner; the limits of birds in flight; the limits of man above sea level by 26,000 ft.
Also as Fred has pointed out- the cost that mutations bring with them. Then we have the 3D protein structure. How many different shapes can one protein take before it no longer binds to other proteins? joz:what are the limits on NS and RM? John Paul:OK joz- Please, name a single, unambiguous example of the formation of a new species by the accumulation of mutations. I know Larry is unimpressed with the fact that after millions (if not billions) of generations of bacteria not even one 'evolved' into something other than bacteria. The same for a virus. Yet we are supposed to believe (according to the ToE) that great transformations (whale evolution for example) can occur in less than 1 million generations. -------------------------------------------------------------------------------- ------------------John Paul

The limits you state are not relevant so if you are aware of any that are please state them, I suspect you dont because you cant....
If you cant show there are limits why insist they exist? I have a feeling that maybe it is because if you once conceded that if there is no evidence for something it is pointless to stipulate its existence you would have to reassess your position on the existence of God (moving to a "God is possible but with no evidence it cannot be claimed he definitely does exist" position presumably)... So do you have any relevant examples or is it another case of "I think this so it is necessarily true"?

joz:
The limits you state are not relevant John Paul:Just saying so doesn't count. Each example was of a living organism. Also please explain why the cost argument and protein structure argument are not relevant. joz:so if you are aware of any that are please state them, I suspect you dont because you cant.... John Paul:I stated them and you only response was a non-response. joz:If you cant show there are limits why insist they exist? John Paul:Then if there are no limits why do ALL our experiments show differently? joz:So do you have any relevant examples or is it another case of "I think this so it is necessarily true"? John Paul:I gave relevant examples. I am waiting for any evolutionist to provide evidence that random mutations culled by natural selection can lead to the great transformations required if the ToE is indicative of reality. And I see you conveniently avoided this: John Paul:OK joz- Please, name a single, unambiguous example of the formation of a new species by the accumulation of mutations. So far all you have is argument from personal incredulty- not quite science now is it? ------------------John Paul

quote: First how does the fact that most mutations are bad work as an example here? NS solves this by breeding the "bad" mutations out.... Second protein structure we have proteins, bacteria have different proteins, both sorts work, you have not identified any mechanism that prevents "small changes adding up" to change from one to the other.... This example could quite possibly be used to constrain the types of organisms possible but not to refute the concept that types of organisms can evolve into different types.... So that would make all of those examples irrelevant... Back to you... [This message has been edited by joz, 12-20-2001]

[QUOTE]Originally posted by John Paul:
[B]Larry: The larger problem is you misrepresent the evidence for common descent of chimps and humans from a common ancestor. You simply cite the 99% common genetic code. This isn't really the best evidence of common ancestry. The best evidence is the shared pseudogenes and retroviral insertions. The common nature of such genetic material without any function shared within a nested hierarchy of species is quite compelling. John Paul:Common mechanism can also explain shared retro-viral insetrtions and pseudogenes.[/QUOTE] I already responded to this, but here it is again:
http://www.talkorigins.org/faqs/comdesc/section4.html "Prediction 21: Nonfunctional molecular evidence - Endogenous retroviruses Yet another nonfunctional example is given by endogenous retroviruses. Endogenous retroviruses are molecular remnants of a past parasitic viral infection. Occasionally, copies of a retrovirus genome are found in its host's genome, and these retroviral gene copies are called endogenous retroviralsequences. Retroviruses (like the AIDS virus or HTLV1, which causes a form of leukemia) make a DNA copy of their own viral genome and insert it into their host's genome. If this happens to a germ line cell (i.e. the sperm or egg cells) the retroviral DNA will be inherited by descendants of the host. Again, this process is rare and fairly random, so finding retrogenes in identical chromosomal positions of two different species indicates common ancestry. Confirmation: In humans, endogenous retroviruses occupy about 1% of the genome, in total constituting ~30,000 different retroviruses embedded in each person's genomic DNA (Sverdlov 2000). There are at least five different known instances of common retrogene insertions between chimps and humans, and this number is sure to grow as both these organism's genomes are sequenced (Bonner, O'Connell et al. 1982; Dangel, Baker et al. 1995; Svensson,Setterblad et al. 1995; Kjellman, Sjogren et al. 1999; Sverdlov 2000). The Felidae (i.e. cats) provide another example. The standard phylogenetic tree has small cats diverging later than large cats. The small cats (e.g. the jungle cat, European wildcat, African wildcat, blackfooted cat, and domestic cat) share a specific retroviral gene insertion. In contrast, all othercarnivores which have been tested lack this retrogene (Futuyma 1998, pp. 293-294). Potential Falsification: It would make no sense, macroevolutionarily, if certain other mammals (e.g. dogs, cow, etc.), had this same retrogene in the same location." Now, respond to this. The mechanism of retrovirus gene inserion is well-understood. There is no "magical mystery" mechanism waiting in the wings.
quote: Please explain what you would accept as a transitional fossil?
quote: I've done this already, too, but here it is, again: "Three species of wildflowers called goatsbeards were introduced to the United States from Europe shortly after the turn of the century. Within a few decades their populations expanded and began to encounter one another in the American West. Whenever mixed populations occurred, the specied interbred (hybridizing) producing sterile hybrid offspring. Suddenly, in the late forties two new species of goatsbeard appeared near Pullman, Washington. Although the new species were similar in appearance to the hybrids, they produced fertile offspring. The evolutionary process had created a separate species that could reproduce but not mate with the goatsbeard plants from which it had evolved."
quote: Please define "kind".
quote: Science does not predict that there are no limits to evolution. Evolution is limited by the environment and physical law. Perpetual motion will never evolve, for example, nor will free energy. Creationists, however, claim that there is a limit which somehow prevents speciation, yet they are never specific, as in providing positive evidence, testable predictions, nor potential falsifications, in support of this vague claim. What is your evidence that this is the case?

I make the claim whether as a creationist or a finished study in taught evolution that maintainence of evolution theory by a theory of forces as some philosophy proposes is false and that ecological genetics must get beyond simple criticism of neutral evolution. ToE does not because some of the math in the alternative or rather purely would need be subjectively adhered to which could as an applied mathmetician be taken prima facie against the reinging interpretation of natural selection. Balanced selection need not be refuted howsomeever but examples of programs in nature would need some manifestation (information theory applied to biology) without other changes that may nonetheless be latent.

quote: OK, I am finally going to reply to you and say what I have been wanting to say all along since reading your several posts. I consider myself to have a rather good command of the English language, and to be frank, what you write most of the time strikes me as very similar to post-modern literary criticism, in which the more complicated language one uses in their writing, the more impressed everyone seems to be with the writing. However, I don't understand what you are trying to say most of the time. At all. You will get more replies if you make an effort to explain yourself clearly, without using a lot of jargon.

I suspect Brad McFall has been possessed by the spirit of Dennis Miller. I read his last 4 or 5 posts, and havn't a clue of what he was trying to say.
I must assume it's all a joke.Speaking of which: What do you get when you cross a lawyer with the Godfather? An offer you can't understand. Moose ------------------Old Earth evolution - Yes Godly creation - Maybe [This message has been edited by minnemooseus, 12-27-2001]

Yup, sorry Brad, I must join those who simply don't have a clue what your on about. I'm sure there should be some punctuation going on. That people spell poorly is irrelevant to me, as long as I understand them. But I have to draw the line at the induced asphyxia of a loooooooong sentence, sans commas. It's very hard to read, mate.

quote: Yes, evolution is capable of explaining EVERYTHING, that is one reason why it is a bad theory (in fact it doesn’t even deserve theory status, at best it’s a low-grade hypothesis). Regardless, you continue to evade the point. Percy’s particular analogy did not ALLOW for extinction. It doesn’t matter if evolution can EXPLAIN extinction. Since The fact that Percy’s analogy does not ALLOW for extinction invalidates its application to this debate.
quote: Mutation is NOT new genetic information. If you think this is true, you need to find someone qualified in information science to support you. I assure you you won’t find anyone to come to your aid (if you do, you have done the scientific community a favor by exposing a quack).
quote: You went off the deep end here. How does the environment receive a code? What code does the environment receive? There is no known example in the history of man of a code originating without an intelligent sender. Not one single example. You must have an intelligent sender to create a code. Period. Information science is a dagger in the heart of NeoDarwinism. Fre Hoyle knew it, Francis Crick knows it, but many other evos remain in denial about it because if the implications. It’s 21st century Galileo-ism.

Williams:
Yes, evolution is capable of explaining EVERYTHING, that is one reason why it is a bad theory (in fact it doesn’t even deserve theory status, at best it’s a low-grade hypothesis). This is a prime example of the ignorance of science that runs rampant in creationist circles. Worse, it is a fabricated misrepresentation. That evolution explains things that creationism cannot is a testament to its value as a theory. Creationists often complain that the theory of evolution changes, so it cannot be a good theory. Another example of ignorance. One cannot blame them, I suppose - their preferred 'explanation' will not change in light of new evidence. It will never budge one millimeter. It cannot, lest their Faith be shattered, and that is not allowed. quote:-------------------------------------------------------------------------------- Lbhandli: New genetic information is called a mutation. We observe them all of the time. Perhaps you need to be precise in what you are talking about. -------------------------------------------------------------------------------- Mutation is NOT new genetic information. If you think this is true, you need to find someone qualified in information science to support you. I assure you you won’t find anyone to come to your aid (if you do, you have done the scientific community a favor by exposing a quack). Mutation as such is not information, new or otherwise I suppose. But mutation certainly plays a role in changing and adding information.For some inforamtion from an actual degreed scientific researcher on thsi topic, see, for exmaple: http://www.lecb.ncifcrf.gov/~toms/paper/ev/ As far as the claim that evolution cannot produce 'new information', it appears that creationists are a few decades behind the eight ball. Kimura derived equations in 1961 showing that natsel can in fact produce new information all by itself. There is no known example in the history of man of a code originating without an intelligent sender. Not one single example. You must have an intelligent sender to create a code. Period. I see. Then whom 'sent' the code in DNA? Tree rings? And what is the evidence for this? Information science is a dagger in the heart of NeoDarwinism. Fre Hoyle knew it, Francis Crick knows it, but many other evos remain in denial about it because if the implications. It’s 21st century Galileo-ism. Fred Hoyle also knew that Haldane's dilemma was a sham. In his book "The Mathematics of Evolution", he writes: "Haldane's so-called cost principle is an illusion." (p123) And yet, young earth creationist electrical engineer Walter ReMine uses Haldane as ne of his principle arguments against Neo-Darwinism. Therefore, ReMine's argument is an illusion (ReMine didn't like this fact - in his review of Hoyle's book at Amazon.com, ReMine gushes over Hoyle's amazing math abilities, yet claims he was wrong about the 'dilemma'...)

Is this "new" information then classifiable as modern or post-modern? That is not a silly question for depending on how neutral the position effect (Sturtevant) pans Gould's "gold" out till it is never talked of at all mutation Can give new information. Even assuming we are not discussing differences of mutation that may be percieved in reading Wright's volumnes etc to Sarkar etc. etc. the subcelluar position of mutations along with how it went grammatically for organelles could give new information if macrothermodyamics (author = Gladyshev) recieves this "new" Darwinian narrative. Lane Lester would still be correct however that if ever not how that genetics looks in its eye and this way finds it's enemy. If I am still obscure Mark I did not give up when I was 24 and arrested in New Orleans for talking out loud and about the Pope 1996 saying Darwin and Creation go together. There is an illusion on the yellow brick road to the uncomditioned and the sooner more realize this the less fear of God it will take to turn the point.
