DNA could modify itself with no outside help, say biologists

LOLOL!

>DNA could modify itself ...

Maybe DNA
has a sense of humor and
is effing with us . . .

>Maybe it is Xenu attacking your thetans

"Hey. Is that a joke?
Do I look like I'm laughing?
Life is serious.

Can we talk a bit?
Hey, don't push. Can I leave you
some literature . . ."

Very curious. Thanks for the ping.

I just can't resist another juicy evolution story. Apparently not all the scientists at Princeton are drinking the "everything there is to know about evolution is already known" Kool-Aid.

What an irresponsible thing to say. Your B.S. theory on how science works and how scientists work is just plain wrong. Science is properly set up so that no scientific theory is absolute unlike your absolute belief that Genesis is absolutely correct no matter what.

There are NO good mutations.

Incidentally, there is no law that says the entropy of DNA can't decrease through time.

Can I leave you
some literature . . .

ROTFLMAO.

no scientist has ever claimed such a thing period

True, of course. But perhaps it would be better if you paid no attention to the flaming troll...

“This fascinating and unanticipated new property of DNA has the potential to cause substantial damage to our cells...."

Sounds like a pessimistic democrat..The glass is half empty.

I prefer to be optimistic that this may be the key to the evolution of species whether under the direction and control of a higher being, or not....as you prefer to believe.

Apparently not all the scientists at Princeton are drinking the "everything there is to know about evolution is already known" Kool-Aid.

I was unaware that any leading scientists have made such a claim. Do you have a reference?

Looks like the Law of Entropy strikes again, and the biggest objection (apart from irrationality of matter being eternal) to genetic evolution stays.

What, exactly, does the "Law of Entropy" state?

There are NO good mutations

I am afraid that your claim is demonstratably false.

not all the scientists at Princeton are drinking the "everything there is to know about evolution is already known" Kool-Aid.

Could you point us to a list of those who claim we know everything? Thanks

Great post. Thank you. Let the debate begin again.

Why did you double-post the nylon bug?

Let me guess, "Nothing beats a great pair...of L'Eggs!"

Cheers!

But the team found that if a stem-loop forms from a particular sequence of DNA, one of the genetic “teeth” will fall spontaneously from that side of the zipper, and the weakened strand will eventually break apart in that spot unless it is repaired by enzymes in the cell. Fresco said this sort of activity seems akin to self-mutilation at first glance.

Reminds me of how often the crevo threads themselves "unwind" over time ;-)

(Heads for exit, running for cover...)

Cheers!

There's a list? Its worse than I thought.

Must be a "bug" in my coding. : )

I can point you to a leading Korean scientist that's good at cloning, or perhaps you're interested in claims of cold fusion?

Gosh, you got me. I don't have a quote of a "leading scientist" saying, "I declare that there is nothing more to learn about evolution." However, finding a lot of quotes that say the equivilent of, "What total nonsense, shut up" isn't that difficult. I believe that's pretty much been the line on contrary scientific thought since about 50 A.D.

" I can point you to a leading Korean scientist that's good at cloning, or perhaps you're interested in claims of cold fusion?"

You mean those people said that,

"everything there is to know about evolution is already known"?

That's odd. Evolution had nothing to do with their fields. I am sure you can provide documentation though, you wouldn't just make things up...

" However, finding a lot of quotes that say the equivilent(sic) of, "What total nonsense, shut up" isn't that difficult."

Then produce them.

So you just made it up, the part about science claiming to know everything.
