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.

And someone who goes by the moniker of Demensio is to be taken seriously?

I would have been a little more careful in picking a screen name since it is so easily changed with only one letter to Dimentio or Dimensia --not that I would take a cheap shot like that. Just an observation.

[Aric2000]

damn 1301, oh well

[ALS]

kinda sensitive about that moniker ain'tcha
relax bubby it's just words on a screen

[Aric2000]

And you still fail to grasp it, AFTER I have explained it to you twice, damn, you ARE an idiot.

[ALS]

I was gonna mention that but I'm reeeeeeeelly sensitive to his sensitivity n stuff

he could go postal anytime now

[Aric2000]

All doubts in my mind are gone, fully certifiable, too fricking funny!!!

[Dimensio]

How sad that his genetic material has not been weeded out of the general population through natural selection. Ahwell, no more replies to him. I think that I will converse with something a bit smarter than ALS, such as a sack of bricks.

[ALS]

more projectionism


you didn't go see that shrink like I suggested, did you

[Dataman]

That's impressive. It's not only in context, it's left the evos speechless.

[ALS]

"Ahwell, no more replies to him"

I've heard that one before....

[jennyp]

"Does entropy affect threads too?" PLACEMARKER.

[ALS]

these two make quite a lovely pair don't they?

[ALS]

""Does entropy affect threads too?" PLACEMARKER."

depends on who enters one

[Aric2000]

This thread is now officially considered dead, the asylum has taken over, the hopes of thoughtful debate is now lost.

All hands abandon thread, all hands abandon thread.

[donh]

those opposed to evolution can find numerous counterexamples of living things

Ring me up when you can produce an example of a zebra and an octopus breeding a housefly, or a newsphoto of God spontaneously producing a totally new species with a totally new form of DNA encoding. Until then, we'll dismiss your poor attempt at humor with the usual caution: just because you don't know how something was done, doesn't make it automatically a miracle.

[ALS]

Finally realized the utter stipidity of your quote and now you want to wish it all away to the corn field eh...

[Dataman]

Snap!

a complete, utter and total drooling moron

hope that you have never and will never reproduce

a retard like yourself

you're just too stupid

Of course all those quotes were out of context.

[PatrickHenry]

All hands abandon thread, all hands abandon thread.

You are quite late in coming to this conclusion. But I welcome your belated enlightenment. Leave this thread of fools. Do it now.

[donh]

"My attempts to demonstrate evolution by an experiment carried on for more than 40 years have completely failed.

Unlike those of hundreds of other experimenters, including many engaged in industrial micro-biology.
