Re: Rapid change.
Rapid change in phenotype doesn't necessarily imply an increased mutation rate. Rather, new and strong selection pressure can be working on existing variation.
--------------------------------------------------------------------------------
I would tend to to agree with you. But it could also mean that changes originated from neural system may be intervening. (see http://www.sleepgadgedabs.com). Your use of the word "rather" i suppose you imply that you accept the possibility, that other things could be happening as well.If strong selection pressures is the only couse, which might well be true, then it has to clearly beyond any doupt be proved; and particularly it has to be sure that other co-working couses are excluded.

Re: Rapid change.
O.K Percy,
but what if in a thread i read a question or an issue that could IMO give an answer or a new direction to the discussion related to the issue? In that case you may give the impression that you are afraid of discussing the issue from all possible views-sides.

Re: Rapid change.
If you would like to continue working on the topic proposal you began (Did evolution evolve?) then let me know and I will reopen it.
Yes please.

Re: Are there RANDOM MUTATIONS?
What if it didn't?
So regarding the issue of tendency for life preservation we are equally footed. It is a matter of belief.I believe there is, you believe there is not, becouse there isn't any evidence of it.I can understand it.Can we agree as honest men on this?

Re: Are there RANDOM MUTATIONS?
You can not see any tedency in nature. But this again is a belief.
How can you say that after 200+ posts where we discussed a paper that demonstrated those tendencies?
I din't understand it. What do you mean by "those tendencies"?
What is anyway your evidence that information is not guiding evolution?
My evidence that fitness is not guiding mutation is that the increased mutation rate was specific to ssDNA, not the leuB gene.
The question is quite different.

Re: Are there RANDOM MUTATIONS?
The tendency for mutations to be random with respect to fitness.
I think "respect to life preserving" is more appropriate, as wider and more representative term.Also it touches the issue at the core and makes it more difficult to defend.
