Jerry. I am not supporting creation OR evolution. Please get this into your head. UWO does not know the answer, hence he asks. Ok? Cool.
Worthy, I completely understand that you are riding the fence at this point. The reason I said that you had fallen victim to a creationist ploy was that you were sincerely asking one of "their" questions as though it was meaningful - putting a fairly large burden on those who answer the question to also demonstrate why it isn't relevant in the first place. They do have questions that "seem important" that I cannot answer apart from merely pointing out that they are very much beside the point. This isn't one of them, but don't be suprised if one should come up. Going on...
Thanks for your explanation. Now....Why don't you have to show me an example of something that is accepted as necessary to happen for evolution to occur?
The simple answer is that we already know that evolution is occurring, has occurred, and is the (natural) reason for the diversity of life we perceive today. We might be wrong in thinking that mutation is the greatest source of new genetic variety, but we know that the new genetic variety came to exist by some means, and we have good reason to believe that mutations were among the prime culprits, if not the only ones.
That having said, "information"-increasing mutations have been observed, no matter how you define "information", but depending on how you mean "observed." No one had the microscope on the pollinization of a plant as it became polyploid, but by counting chromosomes in the parent species and the species that has been documented to be descended from that parent, when a polyploidy has occurred, we can very much say that the polyploid event was observed.
found here: http://www.talkorigins.org/faqs/faq-speciation.html5.1.1.2 Kew Primrose (Primula kewensis)
Digby (1912) crossed the primrose species Primula verticillata and P. floribunda to produce a sterile hybrid. Polyploidization occurred in a few of these plants to produce fertile offspring. The new species was named P. kewensis. Newton and Pellew (1929) note that spontaneous hybrids of P. verticillata and P. floribunda set tetraploid seed on at least three occasions. These happened in 1905, 1923 and 1926.
Polyploidy doubles the total number of nucleotides in the DNA of an organism, so by your criteria, "All I want is one example that the DNA strand was lengthened and survived the entire process," this example qualifies, though I cannot guarantee you that this example polyploid event is "beneficial". Why need it be? If beneficial mutations can occur in genetic material, and gene duplication (or even genome duplication in this case) can occur, why must they occur at the same time?
It would be necessary that this be able to be passed to another host or being through a natural process.
Obviously, since the allopolyploidy restored fertility to the strain of plants it occurred in, this condition is met.
I hope this helps.
Jerry
