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.

I question the sincerity of nominal Christians when they quote words to imply the opposite of what the original speaker intended. It's a simple matter of personal honesty.

Are you suggesting that ALS is a Christian?

YOU have chosen to assert religion on US, but have utterly failed to assert religion on THEM. Denial is pointless, so just answer the simple question as to WHY.

I hold you to the commandments of your religion because I believe they are important to you. The quote that started this discussion was dishonestly presented. I assume you copied the quote in the innocent belief that it accurately reflected the thoughts of the author, but you were mistaken. I hope you will come to understand that falsely presenting peoples' words as testimony against them is a form of dissembling.

Think of me as the pied piper of posting and all you my little rats...

I assume you are referring to the children's poem. The actual, historical pied piper was a pedophile who lured children away for his own purposes.

ALS doesn't fit your stereotype, does he? He's been having fun with you guys...

Is that the True Christian's idea of fun -- lying?

At least effdot quoted the whole statement, indicating that Darwin believed in his hypothesis. Unlike some "Christian" websites.

I mean no blasphemy here.

Your stomach is being grilled in Hell. Baghdad Bob tells me so.

One could put together much worse "blasphemies" following the ground rules in the ALS quote.

The serious question here is not the "you're a liar" name calling we all love to engage in, but whether anything at all is gained tby playing the game of gotcha.

Good question. Perhaps I made a hasty assumption.

I didn't consider the possiblity that ALS is a good Muslim. I suppose I'll be sent back to PC school for this, and it'll go on my permanent record.

False assumptions and jumping to conclusions. That's what evolution is all about.

Actually, I'm asking more specifically about where in the fossil record we might find the examples of those early multi-celled creatures which were just beginning to develop complex skeletal, neurological, respiratory, circulatory, and gastrointestinal systems.

For the Theory of Evolution to be credible, life had to have evolved from single celled organisms with very simple systems, to multi celled organisms with very complex, interdependent systems (i.e., the cells in the lung need the red blood cells from the circulatory system to do their work, the muscles which power respiratory and peristalsic intestinal action require both the circulature and a nervous system to guide their work, etc.,... as in "interdependent").

In as much as these complex systems are inescapably dependent upon one another, they must all have developed at rougly the same time to have survived the "survival of the fittest" cut. When was that? Where is the fossil record of that?

The fossil record, however, contains only the former (simple, single celled) and the latter (complex, multi system) with no fossil evidence of the billions of missing "developmental" stages.

If they existed, there would have had to have been billions of them, and we would surely have found some by now.

On the other hand, the existing fossil record does comport with the Biblical History of Creation. Oceans first, then creatures, with no "evolutionary" link between the two.

That you are trapped into depending on man's (and your own) intellect for explanations about such things makes it easier to understand why you are blind to the Truth. But your blindness does not make Truth a lie, nor will it ever make a lie the Truth.

I send my sincere condolences about all those "peer reviewed" papers you've wasted so much valuable time on. There nontheless remains hope for you for so long as you draw the Breath which God Breathed into you.

Changing the subject again? let's return to it:

Is lying acceptable to Christians? Is it fun?

When the gene pool of a set of organisms becomes quite small, its dissappearance is quite likely.

Oh, and by the way, Mr. Science, the detailed reason scientists have this concern is because an insufficient population in bisexuals means the loss of all the possible instantaneous variations in genetic composition that recessives and other exchange permutations with similar effect to the recessive mechanism make possible. In other words, too much the capacity of a species to cope with it's environmental changes by altering it's physical capacities through genetic reformation is lost.

In effect, a bisexual species is really, in comparison to unisexuals, a vast conglomeration of species always ready to zip out from the drawing board in response to the environment. Externally caused mutation isn't really the biggest player in the DNA story, if it ever was.

Tentative assumptions and agonizingly dragging to provisional conclusions--that's what science is all about.

You are correct. I jumped to conclusions. I went back and read all the ALS posts in the first 600 or so post in this thread. I found these, where he appears to disparage athiests:

To: Dimensio

Using your logic:
So you're an atheist, which means you can't possibly understand creationism.

But I see no evidence whatsoever in any of his posts that he is a Christian. Either in his words or in his demeanor.

I apologise.

"We have information that will blow evolution out of the water, but it never comes to light?"

For those who are blind because they insist on living in darkness, who rebel with every fiber of their being against the Light of the World, there will never be enough lumens to help them to see, for theirs is not a physical malaise but rather a disease of the soul, of the spirit.

The Light shines now just as brightly as ever on the Truth, and you need only have the scales removed from your eyes to see it. That, however, is your choice, and yours alone.

If I could do it for you, I would. But only Jesus Christ can perform that miracle. Take heart in the fact that He performs it every day, and has for over 2,000 years.

That invisible Truth surrounds you like an omnipresent glove, and you pay homage to it as does the rest of the world... that is, without even knowing it.

What year is this? 2003? Answer me this;

2003 years since... what?

You mean the post where he compared himself to the woman beater that women always go back to? Or do you mean the posts where he implied that anyone who would converse with Alamo-girl is a sissy?

The fossil record, however, contains only the former (simple, single celled) and the latter (complex, multi system) with no fossil evidence of the billions of missing "developmental" stages.

The best modern take on this development is that multi-cellulars came about as a conglomeration of co-operative multi-cellulars. And, in fact, "fossils" of this circumstance are abundant in, for example, the similarities between the DNA's of certain still-freedwelling prokariotes and their productive counterparts in multi-cellular creatures, such as our mitocondria and plant cell's chlorophyl.

Amongst the reasons you can't find much mineral imprint fossil evidence before multi-cellulars is that there were no mountains rising above the ocean floor, and hence no significant leaching of calcium into the ocean. No calcium, no bones, Sherlock.
