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.

That's like saying something smells like mothballs, then having to explain how you know what moth balls smell like.....
Do you talk to red or brown bricks?

This is beginning to feel like the ALS/Dataman self congratulatory comedy thread or something.
Hey, ALS, look at this stupid picture I found, Yo Dataman, check out this moronic picture that I found.
Evolution is crap, and check out this picture man, oh yeah ALS that is funny, but check this out.
In the meantime, as they congratulate each other on their stupidity and general pigheadedness, they say nothing about WHY they think Evolution is crap.
IT JUST IS, so there....

Because it just is that's why Aric, you moron...
LOL, that 167 IQ is really amusing.
And I still see you using that tagline, telling me that you still don't understand it.
I am laughing at your socalled intelligence.
I don't normally laugh at the mentally deficient, but in your case ALS, I will make an exception.
