A Challenge for Anti-evolutionists

[Greg1234]

Mutation by substitution is no longer seen as the sole source of genetic variation on which selection can act or as the sole factor in the rate at which new variation can appear. It may not even be the primary source of new variation

Nobody said it was. I'm talking about random mutation

In general the mechanisms that have been established function randomly,

They're not. They're directed. There are other such response systems such as "fight-or-flight".

descent with
modification from common ancestors.

Then this isn't a challenge for creationism. A sickle celled man descends from an ancestor with modification.

Why? New genetic variants arise routinely.

The article is about how adaptation occurs.

If you are looking for a limiting factor on evolution, wouldn't you lok at the levels at which they appear in phenotypes and populations,

At the molecular level.

Yep, a transposon creates more frequent appearances of variation.

The stress response is governed by cellular systems and acts through transposable elements. For example,

01/07/30 - ICBP 2000

The importance of the organization of the various lac regulatory sites is that they permit the molecular computations that allow E. coli to discriminate glucose from lactose � that is, to control expression of the lactose metabolic proteins so that they are only synthesized once glucose is no longer available. The basic biochemical reactions and molecular interactions involved in this computation can be stated as logical propositions that can then be combined into partial computations (Table III). These partial computations illustrate the molecular logic allowing the cell to execute the following overall computation: "IF lactose present AND glucose not present AND cell can synthesize active LacZ and LacY, THEN transcribe lacZYA from lacP."

Actually, I believe in a modified punctuated equilibrium that you [probably] don't want to know about.

It's avant-garde, but it effectively explains how the earth was repopulated after the Flood.

I hear what you're saying, I just don't read a lot of fiction.... You know, time's short.

No, you haven't.

That's like saying why shouldn't I believe in Star Wars?

As the rolling intro put it:

A long time ago, in a galaxy far, far away...

It's self contained - you HAVE to believe the Bible to believe that, just as you HAVE to believe Star Wars to believe it happened a long time ago in a galaxy far, far away.

Why shouldn't you believe it? For the same reasons that I don't believe it. There's no evidence to back it up.

You can say "Evidence can take a hike.", but the only reason you say that is because you believe the Bible.

What made you believe the Bible in the first place?

It has been done to the death. Your beating a dead horse.

Indeed. While I have just joined I have followed a couple of AV1611VET's threads. You'd have as much luck taking on someone that believes in Last Thursdayism.
