Here are the undisputed facts:

1. Changes in living things occur at the molecular level.

2. Mutations to molecules at almost always disadvantageous to the organism.

3. Quantum changes occur at the molecular level. “More than a century ago, at the dawn of modern quantum mechanics, the Nobel Prize-winning physicist Neils Bohr predicted so-called "quantum jumps." He predicted that these jumps would be due to electrons making transitions between discrete energy levels of individual atoms and molecules. Although controversial in Bohr's time, such quantum jumps were experimentally observed, and his prediction verified, in the 1980s. More recently, with the development of single molecule imaging techniques in the early 1990s, it has been possible to observe similar jumps in individual molecules.” http://www.physorg.com/news134141862.html

4. Quantum mechanics connects the observer in the macro world to the events at the molecular level.

5. Quantum mechanics allows the observer to determine outcomes at the atomic level. (one can choose whether a “thing” is either a wave or an particle.)

It is a matter of how you interpret these facts. I chose to see this quantum connection as a natural “feedback loop” between the macro world and the world of molecules. I believe that this loop allows a species to adapt quickly to environment factors but not to become a “new” species.

1 Molecular level is not the QM level.
2 So what? natural selection provides a ratcheting mechanism
3. Again so what? Electrons have levels and jump from one to another.
4. learn the difference between the molecular level and the subatomic level.
5. It is always a wavicle. The observer merely chooses how to observe it.
Think of a transvestite. Look up top, you see a woman. Look below, you see a man.
With QM you can only see one or the other.


And whiskey tango foxtrot how does choice enter into it?
I sincerely wish someone would explain this concept to me.

Hey I choose to believe that 2+2=5

Agreed buttershug.

What the poster fails to see is that DNA and genetics is on a molecular level.

When he is describing "molecular feedback loops" he is just describing random mutations already described in evolution theory. He is not describing a change in the mechanism, rather he is simply renaming a mechanism already described by evolution.

As a matter of fact, by focusing on the chemical molecular aspect, he is completely removing the "intelligent designer" influence and inferring sheer randomness as causation, so it is counterproductive from an ID or CS standpoint.

I mean I am no geneticist but I think that is right. Anyone with better information want to expand?

The genetic mutations can be caused by transcription errors in replication or damage to the original DNA by outside interference by energy or other external influences. The contibution of "quantum effects" as far as I know has never been observed or noted nor is it appreciable or significant as far as I know.

Wiki says "The effects of quantum mechanics are typically not observable on macroscopic scales, but become evident at the atomic and subatomic level. There are however exceptions to this rule such as superfluidity." so I guess that would be right at atomic or molecular level.

Also "quantum" effects really do not completely overrule classical newtonian and Einsteinian mechanics as far as I thought until you get into the "Planck length" regime I had thought, so Planck is "6.3 × 10−34 inches, or about 10−20 times the diameter of a proton" according to wiki.

It looks to me like he is trying to ignore known mechanisms already observed and well documented and rewrite the science to attribute them to "quantum" sources, which may appeal to him because the answers are less clear and leave more room for an "intelligent designer"?

Seems disingenuous and just plain misleading or ignorant to me.

it's as misguided as conservation of mass ----> afterlife.

2. Mutations to molecules at almost always disadvantageous to the organism.

At the RNA/DNA level there are 4 base pairs used 3 at a time to code for only 20 amino acids which means that changing one letter will more likely do nothing at all.

Except for small active sites and rare bits of code that must code for the right amino acid, proteins are not at all fussy with usually thousands of ways to make a protein that will do the same thing as another. Therefore even if a mutation did change the amino acid, chances are once again that it did no harm at all.

If mutations were as harmful as some have been claiming they are then all life on the planet would have long ago died of cancer or other.


Quantum mechanics explains what atoms are emergent from. Without the QM world there would be no atoms, no cells, us, etc.. It's VERY important to consider but not required to understand basic microbiology.

QM might be useful in discovering the source of consciousness and where matter came from (in more detail than now known) as well as possible QM information processing (intelligence) so yes it is valuable to understanding life, but have to add the disclaimer that it is not needed to explain the basic science that many like to attack for religious reasons.

no1nose, why do you continue to post threads on quantum mechanics when you don't know any? All you do is demonstrate the pathetic desperation seen in the most vocal of creationists, where they try to grab onto anything they can to try to support their claims even when they don't understand it.
