Opethian,
It is hard to understand how anyone could make this claim, since anything mutations can do, mutations can undo. Some mutations add information to a genome; some subtract it. Creationists get by with this claim only by leaving the term "information" undefined, impossibly vague, or constantly shifting. By any reasonable definition, increases in information have been observed to evolve. We have observed the evolution of
Yep, anything mutations can do they can undo if the circumstances allow them. Again, at this point notice that they do not put a precise definition on 'information'. Some mutations add information to a genome - but they don't define what they mean by information. If they mean addition etc of nucleotides - certainly. But then is sections of DNA which have no function classed as information? Personally i would say it doesn't.
Does disrupting a gene count as a mutation which causes information? It's just removed a gene - ie. Just removed a pile of information. But it has now left a different combination of existing information, which some people may class as 'new information' - but all that's happened is information has been removed, not what i would call addition of new information.
What about gene duplication - no creationist would deny that this happens. So is this an example of a mutation causing new information? Well, certainly it's a duplication of existing information - so how can the information be new? To me it's obvious this isn't new information.
So what is new information. If i described a situation where mutations in a duplicated gene built up until the protein had a new function which was different to the original - now that would be new information. Better still, the original still exists, now we've also got a protein that does something different to the original - maybe it's an enzyme which breaks down a new substrate. That is new information.
Then the new information has to be in the right context for natural selection to select it - but that's another part of the story.
Lets have a look at each of those papers mentioned and if any qualify:
1.
increased genetic variety in a population (Lenski 1995; Lenski et al. 1991)
Cannot find these papers in PubMed (have references in original talk article). So cannot comment on this. You able to read them Opethian?
2.
increased genetic material (Alves et al. 2001; Brown et al. 1998; Hughes and Friedman 2003; Lynch and Conery 2000; Ohta 2003)
Don't have to look at this - i am well aware of duplication and accept that it occurs. I also don't think this is new information as i am sure you don't.
3.
novel genetic material (Knox et al. 1996; Park et al. 1996)
I have looked at these papers' abstracts. Knox 1996 looks at two genes he thinks may have evolved an ancestoral protein. Conclusion is that they
may have. This paper is extrapolating backwards what they think may have happened.
Park 1996 - seems more interesting. They've taken two homologues, which they think might have evolved from a common ancestor. They've mutated the active site of one and induced the antibiotic resistance that the other had. I don't have access to the full paper - i'd be very interested in seeing how many mutations occurred in the active site and whether they were able to keep original enzyme activity through each of the stages of mutation. If not then this would not happen in nature as once the mutation knocks out enzyme activity the enzyme the mutation would be removed by natural selection. Maybe you have access to the paper Opethian?
4.
novel genetically-regulated abilities (Prijambada et al. 1995)
This to me is perhaps the most interesting. The ability to metabolise xenobiotic compounds such as a by product of nylon manufacture. There are other papers that i could point you to should you be interested in this, but no doubt you should be able to find them yourself.
This paper shows how quickly the bacteria gains the ability to digest these compounds - we are talking 9 days here. This was not and could not have been caused by mutation. It was caused by some other process acting on the existing genetic variation. Yomo et al has a few papers - statement he made from his research was:
These results imply that there may be some unknown mechanism behind the evolution of these genes for nylon oligomer-degrading enzymes.
It's an interesting read, so there is something else acting that allows this remarkable adaptation of the P.aeruginosa. I've talked to a few evolutionists and they had commented on maybe writing to the talk origins site to get that section removed from it. But as yet, it hasn't been.
So again we have never observed mutation giving rise to this new information...
