Sorry 'bout that. Post it again and I'll be more than happy to discuss it.Gman wrote:No... You purposely deleted my quote about "seeding". You only responded to what you wanted to.
Sure I've heard of this. But your assertion was that the "majority of scientists" accept panspermia. "Majority of scientists" is a quantitative assertion. Can you back up this assertion?Gman wrote:Ever heard of these scientists? Though it is hypothetical and currently unproven...

Ok, what specifically have they determined is "designed"?Gman wrote:Again... All ID is concerned with is finding design.
If it invokes the supernatural, it is untestable and thus, unscientific. If you disagree, please explain how you propose we test the supernatural.Gman wrote:Design could very well be from the supernatural or "seeding" from other planets or from aliens.
Can you give a specific example of any of these fields using the same "principles" that ID creationists have proposed?Gman wrote:Also a quote from our website...
"The claim has been made that ID has no place in science and is never used in the study of science. This is not true. In fact, all of the following areas of science use evidence of ID as the major or sole means of study. Even though the designer is not a supernatural agent, but intelligent humans, the principles involved in studying these areas of science can be applied to the study of supernatural ID."
1. Archeology: Is that rock formation natural or due to intelligent design?
2. Anthropology: Do sharp, pointed rocks occur naturally or are they designed by intelligent beings?
3. Forensics: Intelligent cause of death or natural circumstances?
4. SETI: Are those radio signals natural or caused by intelligent beings?"

Facts are observations. We observe populations evolving every single day, thus evolution is a "fact". "Proof" is for axiomatic systems like math, or for law. Science is about providing evidence.Gman wrote:Then why do you propose calling Darwinian evolution a fact?? If you call it a fact, then it's already been proven.... How do you re-prove a fact?Gerald McGrew wrote:Science does not "totally prove" things.
Both.Gman wrote:Evolve in what way? Adapt to it's environment or morph into an entirely new species?Gerald McGrew wrote:Since every population we've ever studied evolves (we've never seen a population not evolve), why should we conclude that populations in the past didn't evolve?
But that's not what you stated earlier. I explained that the earth and life sciences community have held the exact opposite of your opinion for over a century, and you responded: "Overwhelming opinion? Legally it's the ONLY opinion... ". I didn't say anything about public school curricula.Gman wrote:Ever heard of the separation between church and state? It is currently illegal to teach anything except naturalism in the public schools..Gerald McGrew wrote:I'm not sure what you're talking about here.
That doesn't make any sense. Again, why did you shift definitions in the middle of the discussion after I demonstrated it to be an observed fact?Gman wrote:To show you that it doesn't exist...Gerald McGrew wrote:Well, now you're moving the goalposts on me. Earlier, you posted a link that gave the following definition for "macroevolution":I operated in good faith from that definition (and even stated, "If you define macroevolution that way....."). You did not immediately point out that you defined "macroevolution" differently. But now that I've given an example that fully satisfies the above definition of "macroevolution" (that you provided), you suddenly present a new link that offers a completely different definition: "Extrapolation of microevolution to account for all changes in body designs, speciation, appearance of new phyla, etc.""Macroevolutionary studies focus on change that occurs at or above the level of species"
Why did you do that?
Those definitions seem a little odd.Gman wrote:"There are two major models of macroevolution (In the remainder of this article, I will refer to macroevolution simply as evolution, since this is the common usage). They are:
* Gradualism - Changes in the morphology of species are the result of gradual changes in the genomes of species. The apparent lack of gradualism in the fossil record is due to an incompleteness of the fossil record.
* Punctuated Equilibrium - Changes in morphology are due to species sorting following geographic isolation and major reductions in population numbers. The punctuated appearance of the fossil record is real.
First, if "gradualism" is "gradual changes in the genomes of species", what is PE in terms of pace of genetic changes? If you're going to contrast the two, you should contrast them on the same terms.
Of course. Why would we expect the preservation and discovery of every species that's ever existed?Gman wrote:The major problems with gradualism is that it is not reflected in the fossil record. By far, the fossil record is extremely discontinuous. There are a few examples of gradualism, but they are the exception.
But what about the examples of gradualism that are in the fossil record? Do we just wave them away?
What exactly does that mean ("a lack of intermediates for most species")? Do you mean intermediates between species?Gman wrote:Even the most famous example of gradualism (the horse) suffers from a lack of intermediates for most species.
What exactly do you think he's "admitting"?Gman wrote:Here is an admission by an evolutionist:
"Eldredge and Gould not only showed that paleontologists had been out-of-step with biologists for decades, but also that they had unconsciously trying to force the fossil record into the gradualistic mode. The few supposed examples of gradual evolution were featured in the journals and textbooks, but paleontologists had long been mum about their 'dirty little trade secret:' most species appear suddenly in the fossil record and show no appreciable change for millions of years until their extinction." Dr. Donald Prothero
Ok...the fossil record shows examples of both gradual evolution and PE. And....?Gman wrote:The evidence against gradualism is extensive, but not readily admitted to in the popular press or textbooks. Although the fossil record for a given location on land may be discontinuous, the fossil record for organisms deposited in the ocean or large bodies of water is continuous. Studies by Stanley (3), Cheetham (4) and Stanley and Yang (5) examined all the available lineages of their respective groups (bryozoans and bivalves) through long intervals of time, using multivariate analysis of multiple character states. Both concluded that most of their species were static through millions of years, followed by the sudden appearance of new species. Williamson (6) examined the fossil record of mollusks in Lake Turkana, Kenya, and showed that there were multiple examples of rapid speciation and prolonged stasis, but no gradualism. Barnosky (7) examined a large number of different lineages of mammals, from mammoths to shrews and rodents that lived during the last two million years of the Ice Ages and found a few examples of gradualism, but many more which showed stasis and punctuation. Prothero examined all the mammals with a reasonably complete record from the Eocene-Oligocene (about 30-35 million years ago) beds of the Big Badlands of South Dakota and related areas in Wyoming and Nebraska (8). This study not only sampled every available lineage without bias, but also had much better time control from magnetic stratigraphy and wider geographic coverage than previous studies. With only one exception all of the Badlands mammals were static through millions of years, or speciated abruptly (if they changed at all). Stasis and sudden appearance of new species is the norm rather than the exception, as evidenced by the fossil record.
I would agree that the fossil record will never give a complete picture of the past, but that does not mean it cannot tell us anything at all. Again, in the fossil record we see both gradual evolution and PE.Gman wrote:Evolutionists have used the excuse that the fossil record is not complete enough to be an accurate representation of the history of life on the Earth.
90% missing is "surprisingly complete"?Gman wrote:A recent book, The Adequacy of the Fossil Record (9), examined the fossil record in terms of its completeness, bias (over and under representation of certain species and groups of organisms), and stratigraphic range (its completeness for a species over the entire history of its existence). Their conclusions were that the fossil record is surprisingly complete, with about 10% of all species that have ever lived being represented.
Ah, so if someone were to say....statistically analyze the relationship between stratigraphy and phylogenetics, would you agree that would be a valuable exercise?Gman wrote:There are some biases and stratigraphic incompleteness in the fossil record, but these problems can be estimated mathematically from the available data. There are many examples of stratigraphic gaps in the fossil record, with these gaps being the rule rather than the exception. In the past, it has been assumed that the gaps represent incompleteness of the fossil record. The authors suggest the "heretical" view that stratigraphic data should be used to test the phylogenetic relationships between species rather than assume that the relationships exist and that the fossil record is incomplete.
????? The evolution of mammals is one of the best represented events in the fossil record. It's often used to calibrate molecular clocks. The assertion, "Many scientists had claimed that gaps in the fossil record could account for the apparent sudden appearance of mammals" is an uncited, unreferenced bald assertion.Gman wrote:The punctuated fossil record applies not only to individual species, but to entire periods of time, where entire communities of species remain unchanged for millions of years. These periods of "coordinated stasis" can be followed by periods when "upwards of 60% of species seem to be replaced over a period of a few hundred thousand years"(10). During the first 16 million years of the Tertiary period, 18 orders of mammals appeared. Many scientist had claimed that gaps in the fossil record could account for the apparent sudden appearance of mammals.
I wanted to look at the citation for this, and I was surprised to find that the cite isn't actually to Dr. Archibald's work! And when I clicked the link next to the cite, it didn't work ("Page not found"). All that seems rather odd.Gman wrote:However, Dr. David Archibald (San Diego State University), looked at the numbers of fossil site spanning the period of 5 million years before and after the Cretaceous-Tertiary boundary. Dr. Archibald found that sampling was equal for periods before and after the boundary, although only 11 genera were found in the 5 million years before the beginning of the Tertiary compared to 139 genera in the 5 million years following (11).
???? But this copy-n-paste was just attempting to address PE, which posits that the gaps are due to modes of speciation. So this assertion/conclusion does not follow from what came before.Gman wrote:The idea that the lack of transitional forms is due to gaps in the fossil record is not reasonable given the tremendous number of fossils that have been discovered in recent studies.
But this copy-n-paste stated earlier that there are examples of gradual evolution evidenced in the fossil record. So how is something that is seen in the fossil record "not supported by the fossil record"?Gman wrote:Therefore, the old "evolution of the gaps" theory is not supported by the extensive fossil record that now exists. Gradualism, although it seems a more logical mode of evolution, is not supported by the fossil record.
Where does this assertion come from? No cite, no reference?Gman wrote:Refutation of Punctuated Equilibrium
Punctuated equilibrium requires the occurrence of two unlikely events. First, a number of beneficial mutations must accumulate in a small number of individuals.
How is "low" defined above? What is a "low mutation rate"?Gman wrote:Since the mutation rate is low, the species' population must be large in order to accumulate any beneficial mutations (most mutations are neutral and the remainder are mostly detrimental).
Why is that unlikely? We see it happen.Gman wrote:Next, these few individuals must become genetically isolated from the larger population (species sorting). Without genetic isolation (usually involving geographic isolation) the multiple mutations, needed to produce the punctuated appearance of a new species, would never get co-expressed.
This seems to be a straw man argument. The total lack of citations or references in this section speaks volumes.Gman wrote:Therefore, punctuated equilibrium requires the unlikely events of multiple mutations in presence of a few individuals of large population, and the unlikely genetic isolation of these specific individuals from the vast majority of the main population.
Sure, when you have "drastic reductions in numbers". PE does not require such dramatic reductions. Again, this is a straw man.Gman wrote:A recent study destroys the idea of species sorting (20, 21). Instead of becoming a new species, populations that suffer drastic reductions in numbers are characterized by decreased genetic variability and an expression of detrimental genes.
That would be true if PE revolved around such dramatic population reductions. Since it doesn't, the author is guilty of argumentation via straw man.Gman wrote:This happens because normally heterozygous (containing 2 different alleles of each gene) individuals become homozygous, due to inbreeding. As a result, detrimental, non-expressed, recessive genes become homozygous and, therefore, are expressed, resulting in a less fit population. The study examined the effect of a 35-year population decline of greater prairie chickens on their fitness and fertility. The results showed that population decline and isolation of the prairie chicken led to decreased genetic variability, reduced egg viability (from near 100% to less than 80%), and a decline of fertility rates (from 93% to 74%). Only after human intervention (which brought in genetically diverse individuals from other areas) did the population begin to recover. This study calls into serious question species sorting as the underlying mechanism of punctuated equilibrium. More recent studies have confirmed these results (22, 23).
The paper does not say "prevents the kind of species sorting expected in punctuated equilibrium" at all.Gman wrote:Another study showed that low relatedness (high genetic diversity) is favored in social insects (24). This low relatedness improves the fitness of the colony, but prevents the kind of species sorting expected in punctuated equilibrium.
I provided an example of observed speciation HERE. The new species is physiologically unable to breed with its parent species, but fully capable of breeding on its own.Gman wrote:Not that I'm aware of. By the way, please explain in detail how evolution accounted of a new species. Just don't point to a link...Gerald McGrew wrote:I provided an example of the evolution of a new species, which is "macrovevolution" as defined by the link you provided.
Ok.Gman wrote:Please do... And I want you to be very specific in great detail.Gerald McGrew wrote:As I said, I would be happy to discuss the Cambrian with you, but I would prefer to cover the topics we are discussing now first. Would you like to start another thread on the Cambrian?
You didn't answer the question. Who taught you that evolution is "a fish morphing into a human"? Also, "Youtube" is not a scientific source. So once again, can you provide a scientific source claiming that evolution is "a fish morphing into a human"?Gman wrote:Are you serious? Can I ask how long you've been studying evolution? Please view this you tube link that explains the evolution of man from the "very" beginning... The link doesn't specifically address macro but it is implied...Gerald McGrew wrote:By whom? Please be specific. And can I take it then that you are unable to provide a citation to a scientific source that claims "macroevolution is a fish morphing into a human"?

Because it doesn't invoke the supernatural.Gman wrote:Our topic is "ID...why isn't it religion?" You say that ID is a religion but why isn't your belief a religion??
So in your mind, things are either absolutely proven or they are "faith" and "religion"?Gman wrote:Again.... Where is your proof? If you don't have any proof then you have to accept it on faith. A religion. Your religion...
????? Why would the question be for me? You tried to quote Gould to support your assertion about the absence of transitional fossils. I showed where Gould very clearly stated that transitionals are "abundant" and expressed his frustration at creationists misquoting him as saying otherwise. And that's my issue? LOL!Gman wrote:That question is for you... It seems blatant to me that the left hand doesn't know what the right hand is doing here....Gerald McGrew wrote:Of course not. But it's obvious S.J. Gould held the opinion that transitional fossils are "abundant" and that he was very annoyed when creationists took his quotes out of context to make it seem as if he held the opposite view. Earlier, David stated that "transitional fossils" were evidence for macroevolution. You responded:Now, why would you quote a man who believed that transitional fossils are "abundant" and claim that he believed otherwise?"Not according to evolutionist Stephen J. Gould."
???? What does the origins of life have to do with "Darwinian evolution"? Further, are you operating from the position that "faith", "belief", and "religion" are insults?Gman wrote:Then your Darwinian evolution is faith based... A hypothesis... Your belief...Gerald McGrew wrote:I agree with Dawkins' statement. But it has nothing to do with the subject Gould was talking about.
