Out of interest have you ever observed the differences between the DNA of the 'ancient' bacteria, and the human genome?
I will be a lot more interested when I've seen someone who has actually studied information theory making the "no new information" argument; for now, I think it's just lack of clear understanding of what "information" is.
Bacteria and even the oldest eukaryotes (protists) have a rather small genome. . . . This raises the question: By what process is a new gene produced? This occurs, most frequently, by the doubling of an existing gene and its insertion in the chromosome in tandem next to the parental gene. In due time the new gene may adopt a new function and the ancestral gene with its traditional function will then be referred to as the orthologous gene. It is through orthologous genes that the phylogeny of genes is traced. The derived gene, coexisting with the ancestral gene, is called paralogous. Evolutionary diversification is, to a large extent, effected by the production of paralogous genes. The doubling sometimes affects not merely a single gene, but a whole chromosome set or even an entire genome. [4]
It is the evolution of one species from another, which is what you were previously say didn¡¦t happen. Now you rely on faulty definitions of microevolution and macroevolution to shift your goal post. You can read my sig for the actual definations used in biology. We are discussing science, so lets make sure we stick with using scientific terminology correctly.
Well if simple adaptation can change a mosquitoes breeding site, host preference, feeding, egg preference, and life cycle, then ape ancestor to man is rather trivial.
Not in this case, the populations are reproductively isolated, they won't successfully interbreed.
So missing links are pathways that do not exist. Therefore, pathways that do exist are not missing links.
And thus does not violate 2Lot.
How is it an assumption?
My vote for irony of the year.
So it is an assumption to say that science does not involve the supernatural. Right. . . . So demon possession is a scientific explanation for disease. Thor is a scientific explanation of lightning. The devil beating his wife is a scientific explanation of why the sun shines when it rains. Santa Claus is a scientific explanation of why there are presents under the tree on Christmas Morning. Methinks, that you need a refresher course on the scientific method.
First propose a scientific theory. Then we can debate on the evidence for it.
Can you find a single university with departments or divisions of "junk science," "lab science," and "origin science"?
Reference please, with specific links to scientific journals that are at the forefront of "Junk Science."
Okay, I challenge you to find a single lab in evolutionary biology that does not practice this.
If evolution was so unscientific, why is it the foundation of modern biology?
Let me rephrase that last sentence to make sure that I got it right. Any given gene has a 1e-5 to 1e-6 chance of experiencing a mutation per generation, right? How long is the generation? What species are we talking about?That is over a million chances each generation for any beneficial mutation to occur. Couple that with thousands of generations during the lifetime of a species and you have billions of chances for beneficial mutations to arise. The typical mutation rate of a gene is on the order of 1e-5 to 1e-6 mutations per gene per generation.
It can happen with one mutation. It can happen with millions.
Just go through the scientific literature on human and ape chromosome banding patterns. If that doesn't work, you can generate you own by taking samples and following the standard guidlines of cytology.

Wait a minute, let's not be too hasty. You need to present empirical evidence that proves that this divergence in the species was caused by mutations (macroevolution) and not fluctuations in the gene pool (microevolution). Natural selection cannot introduce brand new genes; it can only redistribute and eliminate them.
There are COUNTLESS changes that have to occur for a monkey to evolve into a man. Hasn't this been debated here before?
You mean, not YET. It hasn't been proven that the two races will not breed with each other at all. And so what if that state does indeed come about...how does that support macroevolution? No new genes have been created.
I'm interested in hearing what you have to say, not talkorigins.org.
Besides, those "found links" are just jumps between the genuses.
Where are the individual fossils of the indermediary creatures between the species that you need for evidence?
Right, because the life on Earth came from life. Simple Law of Biogenesis.
Any time one uses the line "But it must be true" or "But we know it to be true," it's an assumption. You gotta PROVE IT, not assume it.
Just because some earlier theories on supernaturalism were wrong, in no way refutes the truth of supernaturalism.
Nope, they have the respective names of "environmentalism," "natural science," and "paleontology." BTW this is a discussion topic in and of itself.
This is a philosophical argument.... Evolution is in practice today, IMHO, because people WANT it to be.
Not because it's scientifically valid.
Case in point: Karl Marx, who readily accepted Darwin's theory by faith and explicitly stated that evolution was a fundamental tenet of the communist theory.
Let me rephrase that last sentence to make sure that I got it right. Any given gene has a 1e-5 to 1e-6 chance of experiencing a mutation per generation, right? How long is the generation? What species are we talking about?
The thing is, chief, that that picture just doesn't tell the whole story. First of all, it could just as easily serve as evidence for creation: "Common design, common designer."
Second, it doesn't tell the story about how much work it would take to get those genes to evolve from apes into humans.
See, the evidence for evolution is like somebody with HIV: You know the person is going to die, but sometimes it takes a long time.

What is a "pseudogene?"
One principal of genetics that accounts for some genomic diversity are the creation of gene families by duplication and divergence, which Mayr mentions in that quote I gave you. One great example of that family are the globin genes. One important duplication and divergence that occured in our history was the one that lead to fetal hemoglobin. This is what allows placental mammals to exist.

Hmmm. Interesting. It is fascinating to me the way the DNA changes in the hemoglobin. These changes are evidently not random. 'Mutations' occur to suit the needs of the baby at different stages of development. This confirms my understanding of insertions and deletions as given in the book by Lee Spetner who states such changes to the DNA are not random, and they operate on a segment of the DNA. So bits of the DNA can be cut out and reinserted with incredible precision to form a new sequence that suits a particular set of circumstances.
That type of 'mutation' would be quite different I expect to the single nucleotide substitution required in the Neo Darwinian Theory of evolution. Do you know if insetions and deletions can result in changes to single nucleotides only?
By the way, do you support the punctuated equilibrium or the NDT version of evolution.
I note that the example given on the evolution of the hemoglobin is a possible explanation or theory. I wouldn't call it scientific fact.
