Creationists: What is "genetic information"?
I may not have a degree in genetics but I find it telling that the only ones who ever use the term "genetic information" in anything but an extremely loose manner are Creationists.
Thus I would like to give those on this forum a chance to explain precisely what they mean by "genetic information" and how you tell how much "information" an organism has.
Given that I've seen so many claim that evolution must be false because it provides "no new information", I'm curious how you quantify this. Feel free to cite any peer reviewed papers on the subject, I'm sure it will be most entertaining.
So genes then? I suppose that means you all also ignore all cases where gene insertion happens then, because they do get added to. But I'm sure that Creationists already know that, right?

The Genome is the total genetic information of an individual member of a species. The Gene-pool is the total genetic information of a species or sub-species. So to understand genetic information we have to understand how the Genome and the Gene-pool work. Here is an illustration.
In a supermarket you see thousands of different products but you do not want them all. So you make a selection. At the checkout you see that people in front of you have different selections, though perhaps with some overlap. One person may be subject to the selective pressure of a low bank balance so has chosen cheap goods. Another person s basket is filled with foods loved by children, due to the selective pressure of a large family. Now, this all has to do with the idea that natural selection increases the genetic information available in the Gene pool of life.
The total range of in-store products remains the same from week to week, with huge variety available to the baskets that pass through. Thus the inheritance of different genes and gene combinations as one generation follows another can give rise to many different genomes - variations within a species that all derive from the same gene pool. But even within a racial group of humans, no two or us are identical, unless we are identical twins.
Second, nobody carries from the store more than a fraction of the goods available. The shopper has left all the remaining products behind. Likewise, selective pressures in nature can only produce diversification by the LOSS of genetic information. If natural selection causes a species to evolve into two separate species, each of the new species must lack some of the genetic content of the parent genome. Otherwise nothing new has been produced. Natural selection, even when guided by geographical isolation, can never create new genetic information. All it can do is select different genetic baskets from the gene-pool supermarket, leaving the rest behind. Well might Richard Dawkins admit that [quote] contrary to earlier prejudices, there is nothing inherently progressive about evolution. [quote ends, from his book The Blind Watchmaker, p 178]
Mutations are the only factor in evolution theory that might conceivably introduce new genetic information into the biosphere, but there is no scientific evidence that they actually do so. There is evidence of beneficial mutation (as well as neutral mutation, that accomplishes nothing beneficial). But beneficial mutation always involves a loss of genetic information that protects the organism from specific threats, yet they are not beneficial in the constructive sense needed by evolution - of giving rise to increased biological complexity or sophistication. Quite the reverse. Genome degradation occurs.
The wonder of DNA is that it deals with organized information. Randomly formed information DNA molecules would have no information stored within them. They would be blank media. They could contribute nothing towards life-processes. It is not the chemistry of DNA that underwrites life but the information stored in the DNA - information encoded by the meaningful sequence of base pairs and which spells out instructions that the living cell can read, translate and use. Life, therefore, consists not in molecular chemistry but in the information stored by the molecular chemistry. Life is special because it resides not in the chemical media but in the information stored on the chemical media.
Where did this information come from? And why is this information consistently spread throughout all of Earth's living creatures in a way that enables them to replicate reliably? It is due to ingredients that are organized by intelligence, not random chance. DNA is proof of this. But no DNA can work under random conditions. It must be organized, and it takes intelligence to organize information that works consistently through the centuries. That is the 'signature' of the Creator. AiH

"DNA carries the genetic information of a cell and consists of thousands of genes. Each gene serves as a recipe on how to build a protein molecule. Proteins perform important tasks for the cell functions or serve as building blocks. The flow of information from the genes determines the protein composition and thereby the functions of the cell." - Source: http://www.nobelprize.org/educational/medicine/dna...
Edit: You clearly don't get it even though I have provided a clear explanation. DNA is the CARRIER of genetic information. Cheers.

DNA Is Blueprint, Contractor And Construction Worker For New Structures
DNA is the blueprint of all life, giving instruction and function to organisms ranging from simple one-celled bacteria to complex human beings. Now researchers have used DNA as the blueprint, contractor and construction worker to build a 3-D structure out of gold, a lifeless material. Using just one kind of nanoparticle the researchers built two very different crystalline structures by changing one thing -- the strands of synthesized DNA attached to the tiny gold spheres
"It took scientists decades of work to learn how to synthesize DNA," said Mirkin. "Now we've learned how to use the synthesized form outside the body to arrange lifeless matter into things that are useful, which is really quite spectacular."

Scientists dumbstruck: signs of intelligent design in DNA code
Bio-scientists are reeling at the implications of new research published in the prestigious planetary science journal Icarus, which indicates the DNA code of all life on earth contains a pattern that indicates deliberate design.

Genetic information is love provided by our Creator, in the form of a scale: a scale to heaven. That is inside us. We only need to find it, and climb it. Hope this helps. For more information, visit: www.stupidatheistquestions.org.jerk

Creationists accept micro evolution but they believe there is a barrier that stops it becoming something new.

Is it DNA?

Or is it a MESSAGE FROM GOD?!!!
