Startling plant discovery presents problems for evolution

[Startling Plant Discovery Presents Problems for Evolution by David A. DeWitt] "An amazing discovery in genetics has shown that a certain plant (Arabidopsis thaliana) can actually fix a mutation in a recessive allele even when it doesn’t have a copy of the correct sequence in its genome. In a well-designed study, the mutation was shown to be corrected in a “templatedirected process,” not by random mutations. Organisms that have a better DNA correction system would have a survival advantage, but the irreducible complexity of the system makes it highly improbable that it evolved. This correction mechanism has never been seen before and seems to defy evolution by natural selection. How do you select for the ability to fix a mutation that you don’t have? This trait could easily be lost from the population by genetic drift or random mutation in organisms that lack the mutation (assuming it is a DNA-encoded trait). A system that fixes random mutations would stop, or at least slow down, the evolutionary process.

The authors of the study suggest stress induces the repair. Stress has been shown to change mutation rates in certain bacteria, but in the other direction—more mutations are produced to create a variant that can survive the stress. RNA is a candidate for the correction mechanism, but many properties of RNA make it improbable. The RNA may be acting with other proteins, but more research needs to be done. Evolution is such a plastic theory that a “just so” story will probably come about as a result of this correction mechanism. The problem is that it would be just as likely to fix beneficial mutations as it would harmful ones. A creationist can accept this new mechanism as another way of maintaining the created kinds in light of genetic variability."  Evolution Exposed, Second, Ed.  Startling plant discovery presents problems for evolution, DeWitt, Startling plant discovery presents problems for evolution

 

Response to comment [from a "Christian"]:  "Here's a slightly more current discussion of the findings..."

 

Same data, different interpretations.

Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men, according to the basic principles of the world, and not according to Christ (Col 2:8).

Response to comment [from other]:  "Can you post a reply without cutting and pasting the thoughts of others?"

 

You do not enjoy the wisdom found in Christian thinkers? How do you differ with their views?

 

Response to comment [from other]:  "...[Y]et again you show no actual understanding of the science... "

 

I can't understand anything.

Ad hominem.

 

"...[A]re you going to get rid of those lies in your signature?"

 

Alate_One does enough damage in the classroom with a captive audience (Ps 11:3).

You'd prefer anyone passing by TOL be deceived by her, too?
Eph 5:11.

 

"Regardless of which it doesn't excuse your lies..."

 

Proof please.

 

"...in your sig so when are you going to get rid of them?"

 

Why does the signature bother you so? Jn 3:20.

 

"...is vananne your own website?"

 

Yes.

 

I get it. To your mind. I lie. I plagiarize. And I'm only out to promote my own thread. You'll need proof for your accusations. Jn 3:20?

You have zero interest in Arabidopsis thaliana and call me the troll.

 

Response to comment [from a "Christian:]:  "Would you really prefer a raving atheist taught accurate biology to students?"

 

How are you better than a raving atheist? 

 

"Are you ever going to respond to the fact that AiG tells lies and you repeat them?"

 

Poisoning the well.

 

...feather problem.
 

Response to comment [from an atheist]:  "I qualify, can I be your substitute teacher when you are sick?"

 

She is sick and you'd be more honest.


Response to comment [from other]:  "Got that proof for your accusations yet?"

 

Arthur Brain wants answers. :mmph:  We can't make every thread about you. Do you find Arabidopsis thaliana objectionable in any way? :mmph:
