With due respect, Roland I think I have made myself clear enough concerning my OP. I bet I have rephrased it 4 or 5 times.
No
I think so.
Explain theistic evolution for me. I don't get it.
2 important questions you did not respond to:
1. Don't you suspect AAAS was trying to influence public opinion in favor of no-ID in their awards selections?
2. What are the laws governing mutations that result in speciation?
Gidday SamCJ,

You may even have rephrased your OP 20 times. And in those OPs you write:-
(1) AAAS says that these biologists ideas sprang from a belief that mutations are an accident of nature that happen randomly. I simply want a detailed explanation of why AAAS attributes the biologists' ideas to "evolution."
(2) I suspect AAAS gave these awards primarily to influence public opinion in favor of evolution theory. IMO evolution theory to the extent it advocates randomness and denies the possibilty of intelligent design does not deserve any credit for the biologists' findings, particularly the promising findings about the chimps' genome.
(3) I think the answer is the randomness was absolutely irrelevant to the biologists analysis, but that is contrary to the AAAS presentation.
(4) My OP is designed to show the misleading nature of the AAAS awards.
That is you argue that the AAAS either explicitly or implicitly makes the claim. I am asking you to show me where in that article this claim is explicitly or implicitly made by the AAAS!
So far you have not.
I am not being picky here SamCJ, but this does appear to be a central claim of yours, so I am asking you to justify it.
If you rephrase your OP 5 times and in 4 of those you repeat the same argument but with different words, then I am quite entitled to ask you to back yourself up. Dont you think so?
Roland said:
When you write Evolution is presently all about randomness what do you mean? Do you mean Evolution is only about randomness?
SamCJ said:
Well evolution is not all about randomness. Evolution is about many things and random processes are just one part of all this. Sources of variation are not necessarily entirely random as I have explained in an earlier post and I shall deal with this near the end. Evolution is also about selection, isolation, speciation, reproductive success etc.
Roland said:
Atheistic scientists exclude the possibility of intelligence in everything. Does this mean therefore that everything is about randomness according to the atheist?
SamCJ said:
I do appreciate your honesty.
Scientists (theistic and atheistic) have been studying both random and non-random processes in nature for centuries. Atheistic scientists fully understand that many processes in nature are non-random. Therefore an atheist cannot study nature and argue because I am an atheist all things must be random that is impossible.
SamCJ said:

I thought I saw you use the term several times in earlier posts of yours. Because I am not a theistic evolutionist, hopefully my explanation will be reasonable. A theistic evolutionist is someone who accepts, more or less, the mainstream ToE but nevertheless argues that God is behind that evolution in some intimate way. They are, if you like, theistic naturalists. That is, they accept mainstream scientific theories but argue that God is intimately connected with nature such that he his the ultimate author and/or sustainer of things in nature.

1. No I dont. That is why I asked you for evidence. I am not saying that it is not possible. However, I do not think they were trying to influence public opinion. The chimp genome, for example, was high on the list of priorities.
One reason for this was the notion that chimps and humans are closely related. However, the analysis of the chimp genome did not require any evolutionary theory to be successful and no one is making that claim. What is being claimed is that the analysis builds onto Darwins theory.
2. I am not a scientists let alone a biologist and so am not necessarily aware of any laws governing mutation. Because you associate laws governing mutation with speciation, I presume you are asking me for sources of variation within the genome since the theory is that selection acts on these variations to produce novelties, thereby leading to new species of animal.
The sources of variation or types of variation are* (and I do not know if this list is exhaustive):-
1) Spontaneous mutations these occur during DNA replication and repair. For example, things do not replicate correctly and subsequent repair fails.
2) Induced mutations these mutations can be deliberate or environmental. The associated mutation rate is generally above the background level. They are:-
a. Ionizing radiation alpha, beta, gamma and X rays, usually resulting in deletions or insertions of DNA.
b. Non ionizing radiation UV light. Causes adjacent thymines on DNA strands to stick together. These have to be repaired and repair failure leads to a point mutation.
c. Chemicals. These interact with DNA and create base changes. The classes are base analog chemicals, base modifiers, and intercalating agents. Base analogs are chemicals that are similar to bases but have different base pairing properties and can cause transitions from GC to AT, for example. Base modifiers are chemicals which cause improper base pairing. Intercalating agents are chemicals which insert themselves into DNA, leading to replication and transcription problems, resulting in deletions or insertions of bases.
3) Mutator mutations. These are mutations which interfere with the ability of other genes to mutate.
Other sources of variation are:-
1) Gene duplication where genes duplicate within the genome allowing one gene to presumably function normally while the other gene goes on to acquire new functions. Gene duplication is very important in the evolution of plants. It is beginning to be seen as important in the evolution of animals.
2) Chromosome duplication. Here a part of, or the total chromosome set of a plant or animal duplicates. As with gene duplication, this is seen as very important in the evolution of plants, and evidence for it in animals is beginning to be discovered now.
3) Chromosomal rearrangements. These are changes in location of parts of DNA within the genome, resulting in large structural changes. There are two types translocations and inversions. Translocations are movement of DNA to other chromosomes. Inversions are 180 degree flips of DNA within a chromosome.
Some of these variations occur in a non-random manner in that some parts of a DNA molecule will be more prone to mutation than other parts, or some portions will be more prone to rearrangement than other parts. This arises, I believe, due to the differing strength of bonds between and within the different bases of a genome. Also genes within a chromosome are generally linked. That is, if one gene translocates, then the genes closest to it are
more likely to translocate too.
This has been a quick, and I do not know how complete, summary. I hope it helps.
