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.

are you now telling us that Darwin only wrote one letter PH has posted a hyperlink to a letter from Darwin to Asa Gray which says 100% the opposite of what you claim Darwin wrote to Asa Gray. So if your letter is real, and not a lie, why don't you post a hyperlink to it?

says it all...
I thought it was a candid admission myself.
I just read the last 200 posts and am watching the implosion. I don't know whether to laugh or shake my head. It's funny and sad at the same time. Lots of short fuses on the side that claims to have cool objectivity.

So if your letter is real, and not a lie, why don't you post a hyperlink to it? What I tried to find was a letter with the creationoid quote in it, in the expectation of discovering that it was out of context. I couldn't find that letter. Instead, I find a letter in which Darwin vigorously defends his theory. Hard to believe he also wrote the other one.

I hope you are a christian, because if you are, then you know that you will be judged for every lie that you tell, for every arrogance that slips through your mouth.
For everything that you do, there will be a price that you will pay.
Oh, that's right, you are a christian, so you can do whatever the hell you want, because god will forgive you right?
That explains the arrogance then.

I must admit it is quite delicious to watch entropy do its doity deed on the eloonies at large.

Hard to believe he also wrote the other one. Exactly. But it wouldn't be the first time the anti-evolutionists have posted fraudulent quotes.

I posted a hyperlink too Which doesn't contain your fraudulent quote.

You've been trying to call me one for 900 posts so you could bash me with it, now you wished I would so I could inject a morality you've denied?

To: Lurking Libertarian
This is interesting. We have a link to a letter online, from Darwin to Gray, in which Darwin is very supportive of his own theory. As expected, since he's never been known to have rejected it.
On the other hand, we have an unverified claim from a fervent creationoid in which -- contrary to everything ever recorded -- Darwin somehow denounces his own work. No supporting evidence, just the claim of the creationoid.
Whom to believe, whom to believe ....
