Genetic changes in mice 'question evolution speed'

A species of mouse has evolved dramatically in just 150 years, showing genetic change can occur much faster than was thought possible.

The discovery was made by accident by two American biologists studying the genetic make-up of a common wild mouse in Chicago.

Dr Dennis Nyberg and Dr Oliver Pergams, both from the University of Illinois at Chicago, analysed DNA samples from 56 museum specimens of the white-footed mouse dating back to 1855, and 52 wild mice captured from local forests and parks.

They found startling genetic differences between the 19th century and modern mice.

Only one of the present-day mice had DNA that matched that of mice collected before 1950.

While fast evolutionary change has been seen in fruit flies, such rapid evolution in a mammal has not been reported before.

The scientists, whose findings appear in the journal Nature, believe humans may have been partly responsible for the "new" mice.

"Settlers may have brought in mice with the favourable gene that were able to out-compete mice with the native variant," said Dr Pergams.

sure thing

Of course, on the internet, no one's a dog.

Woof! (posted by LL's dog-- my human is away from the computer)

[Right Wing Professor]

btw prof. - do you know the difference between truth and fact?

Y'know, far better men than I have pondered that for quite a while. Do you know irony if it's not flagged ?

[Right Wing Professor]

so you equate the holocaust with the death of evolution?

And when did you stop beating your wife, Rick Santorum?

[ALS]

anyone that would make the claim that all that proceeds from their aura is TRUTH, needs to know the difference.

[Right Wing Professor]

To refute means to disprove. As general_re suggests, you probably mean to deny or to reject.

[ALS]

hey, if he's gonna make such an absurd connection, I will too.

sometimes that's the only way eloons learn.

[Lurking Libertarian]

sure thing

But you didn't (provide the hyperlinks for your [probably fictitious] quotes).

This is not the first time you've done that. (The first time was when you claimed to be posting a link to the "Nobel Peace Prize in Science." The link wasn't what you said it was, because there is no "Nobel Peace Prize in Science.")

Webster sez:
1 : to prove wrong by argument or evidence : show to be false or erroneous
2 : to deny the truth or accuracy of (refuted the allegations)

i can live with these

how bout u guys?

[Lurking Libertarian]

I (and the dog) are out of here. Good night and God bless, all.

[ALS]

I provided you with the same tools I used.

Anyone, and I mean anyone with a web connection can input a quote and get some hits.

you knew that, right?

[conservababeJen]

And when did you stop beating your wife, Rick Santorum?

Oh this comment was very enlightening

You call yourself "right wing"?
hahahahahahhaha
Right of what?
"Professor"?
Professor of what?

You're a lib in 'pub clothing.

[general_re]

And when did you stop beating your wife, Rick Santorum?

Indeed. Very little point in even bothering to address that sort of thing...

"To determine whether two organisms are of the same species one must see if they are able to mate and produce viable reproducing progeny. Such a test is of course impossible when talking of present species and fossils some 100 million years old."

Creationists love this argument no matter how ridiculous it is on its face.

"Indeed. Very little point in even bothering to address that sort of thing..."

or to bring it up in the first place

you're learning

slooowly

[Right Wing Professor]

sometimes that's the only way eloons learn.

All you've done so far is paste silly insults, one dishonestly edited quote that was (magnficently) exposed in a couple of hours, and a few bizarre jabs at people's sexuality most of us had figured out in high school. I gotta say this for you, you take a licking (No, please don't go there!) and keep on ticking. The question is, why? See guy, we're the guys who write stuff about evolution we didn't have to copy and paste. You can't. Doesn't that worry you?

[general_re]

Then why did you bring it up?

[ALS]

"See guy, we're the guys who write stuff about evolution we didn't have to copy and paste. You can't. Doesn't that worry you?"

hehe

spooky thought

I have to tell ya prof. You don't impress me at all.
You fall easier than most and I can't tell yet if it is just naivete or lack of edumacation.

You do carry one asset that is prevalent in most professors though.
Self-aggrandizing arrogance.

hang in there bub

To determine whether two organisms are of the same species one must see if they are able to mate and produce viable reproducing progeny.

Creationists love this argument no matter how ridiculous it is on its face.

And no matter how often they're told it's false. I've given Gore3000 examples of different species that hybridize to give viable offspring. Since he's little more than a damned liar, he pretends he doesn't know about them.

Are you talking about my reply to your reply?

That would be because you "brought it up" firsty.
