Genetic Changes In Mice 'Question Evolution Speed'

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.

Here's something to chew on. I know an IDer on the faculty here at UNL. He's very good at what he does. I won't say too much more about him, because I don't want to identify him, but I did hook him up with a student ID interest group as faculty advisor. (They initially asked me, because they thought, because I'm a conspicuous campus conservative, I must be an IDer. That's how serious the problem of creationism is in modern conseratism, boys and girls) He's violently deluded about evolution, of course, but he's a good scientist. I think most of his colleagues are aware of his views, and because it doesn't impact his immediate field, they leave him alone. Scientists are really pretty tolerant, in the good sense, even about stuff they personally believe is fringe nonsense. None of us are so 100% certain we're right we'll destroy someone's career over it.
Of course, I tell him it's fringe nonsense. He deserves to know the truth. :-)

and all this time I thought you were arguing in favor of evolution. how embarassing to all those that have been blindly supporting your every word. If you don't know that I am a theistic evolutionist, you haven't been reading my posts. And why would you think that theistic evolution is "embarassing" to other evolutionists?
To: Right Wing Professor
Are there any scientists that refute evolunacy that you don't label as "violently deluded"?

ALS is an ALL American Conservative MAN. Oh yeah. Guy who starts calling his adversaries 'gals' and 'cows' as soon as he's tripped up. Yeah, that's one numero uno pure blooded XY male. No insecurities there.
Y'know, as the wife keeps telling me, it is worrying when someone regards the feminine as an insult, don't ya think, conservababejen?

[Me:] "Every one of ALS's quotes
that I have been able to check has either been bogus or taken out of context."
[You:] extreme statement placemarker (note the disclaimer in italics)
You have not provided links for your quotes, so it is difficult to find them (if they're real at all). The ones I have found have either been misleadingly taken out of context, or edited to mean the opposite of what the author intended.

now go focus on the ones you side stepped

'Refute' doesn't mean what you probably think it does. But in any case, no, the scientific evidence for evolution is so overwhemlming I regard rejection of it as deluded to the point of irrationality (or inexcusable ignorance)

However, Turkey Lurkey Libertarian was on this debunking kick and I was just feeding him more straw. he couldn't debunk it either(a)Why the name-calling? ("Turkey Lurkey"? That's an argument?)
(b)Why would I want to debunk a fellow theistic evolutionist?
To: Right Wing Professor
"'Refute' doesn't mean what you probably think it does. But in any case, no, the scientific evidence for evolution is so overwhemlming I regard rejection of it as deluded to the point of irrationality (or inexcusable ignorance)"
that's very open minded of you professor.
did i leave out "scientific"?
So let me get this straight. Anyone who refutes evolution is deluded and irrational, correct?

sorry son, but you are way past all the punchlines
and worse, you've failed to put everything in.... "CONTEXT"!

Everything I post is the truth. Of course, on the internet, no one's a dog. But she, like me, is a non-notorious person, with a different surname (otherwise I wouldn't be mentioning her) who happens to know said washed up celeb. as a family friend. Just one of those 6 degress of separation thangs. So now you're three degrees of separation from your hero/ine.
(And the abuse I get for bringing people closer)
To: ALS
No, 'refute' doesn't mean what you probably think it does. Goddamn it man, you've been speaking it your whole life, try to get literate in it, OK?
To: Right Wing Professor
"Everything I post is the truth."
famous last words
and totally lacking piety
NOT
btw prof. - do you know the difference between truth and fact?

'Refute' doesn't mean what you probably think it does. "Deny" is probably a better word in this context. Some (foolish and bigoted) people deny the reality of the Holocaust - no one has yet managed to "refute" it.

so you equate the holocaust with the death of evolution?
