No... You purposely deleted my quote about "seeding". You only responded to what you wanted to.

Again... All ID is concerned with is finding design. Design could very well be from the supernatural or "seeding" from other planets or from aliens.
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?"

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?

Evolve in what way? Adapt to it's environment or morph into an entirely new species?
Gerald McGrew wrote:Evolution is a "fact" because we see it happen, right before our eyes.
Then why did you say science does not "totally prove" things? Why are you calling it a fact?

Gerald McGrew wrote:Well, now you're moving the goalposts on me. Earlier, you posted a link that gave the following definition for "macroevolution":
"Macroevolutionary studies focus on change that occurs at or above the level of species"
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."
Why did you do that?
To show you that it doesn't exist... Since you chose again not to address it, let's look at what the link says...
"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.
Refutation of Gradualism
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. Even the most famous example of gradualism (the horse) suffers from a lack of intermediates for most species. 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
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.
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. 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. 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 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. 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). 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. 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.
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. 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). 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. 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. Although it is possible that such unlikely events could occur by chance occasionally, punctuated equilibrium requires that these unlikely events occur all the time, as revealed in the fossil record. Punctuated equilibrium truly is a faith in the miracles of chance.
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. 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).
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.

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:
"Not according to evolutionist Stephen J. Gould."
Now, why would you quote a man who believed that transitional fossils are "abundant" and claim that he believed otherwise?
That question is for you... It seems blatant to me that the left hand doesn't know what the right hand is doing here....
