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.

LOL!

I conveniently left out the cream in a can so as not to incite the evo-masses..
however, for entertainment purposes we'll toss in a few bananas

... I have just about decided that ALS is a DU plant, here to troll up some laughs...Or plant some quotes in an attempt to discredit FR and Conservatives in general.
To: Virginia-American
I'm a conservative. Own conservative websites and conservative forums, and love FR.
so your teency twick won't woik.
and best of all, i'm not a hyphenated american!

5{t's an impressive testimony to the capacity of contemporary computer cut-and-paste capacities, but we need a citation. See, we know you looked up a creationist web site, did that ol' mouse drag bit over it, and pasted it onto FR's very nice input box, but some of us are actually going to check out what it says, on the theory that you've only got one strike on you with the Darwin quote, and to be elevated into the Gore3000 pantheon you need at least two more pieces of verifiable creationist lunacy.
So let's have a URL, there, hon?
BTW, my wife says I shouldn't talk to you like this, 'cos I'm just leading you on. BTW, my sister actually knows Boy George. She says he's quite a nice guy, if you overlook the fact he's very gay and very odd.
