Scientists: Virus May Give Link to Life

BILLINGS, Mont. - Scientists at Montana State University in Bozeman say they have discovered a heat-loving, acid-dwelling virus that could help provide a link to ancient life on Earth.

The virus found in Yellowstone National Park could help to understand a common ancestor that scientists believe was present before life split into forms such as bacteria, heat-loving organisms and the building blocks that led to plants and animals, researchers said.

"It's a clue that helps you say, `Yeah, there probably was a common ancestor at some point or sets of ancestors,'" said George Rice, one of the MSU scientists who participated in the study. "It's food for thought."

The scientists' discovery was published in the May 3 issue of the Proceedings of the National Academy of Sciences (news - web sites).

Rice began hunting for heat-loving "thermophilic" viruses in Yellowstone five years ago. In 2001, he and others found several apparently unique viruses associated with an organism living near Midway Geyser Basin where temperatures ranged from 158 to 197 degrees Fahrenheit.

"It was basically something living in boiling acid," Rice said.

Although several new viruses were discovered, one in particular caught their eye.

After characterizing the structure and genome of the virus, they found that its protein shell was similar to a bacterial virus and an animal virus. The similarity suggests to the scientists that the three viruses may share a common ancestor that predates the branching off of life forms more than 3 billion years ago.

"This is something that was predicted but hadn't been shown before," Rice said.

For a long time, scientists classified all life forms as plant or animal. That classification system expanded as more life forms were discovered. Eventually, biologists divided life into five kingdoms — plants, animals, bacteria, fungi and protists.

A more recent approach divides life into three domains: bacteria, eukarya — which includes plants, fungi, animals and others — and archaea, which means ancient.

Archaea, similar to bacteria, is likely the least understood of the domains, according to the paper's authors. Archaea may have been among the first forms of life on Earth. Able to thrive in the hot, gaseous and volcanic terrain of early Earth, they could also survive in the very inhospitable geothermal features of the Yellowstone of today.

Now that scientists know the Yellowstone virus's ancient structure seems to span all three domains of life, scientists plan additional studies on its genes to figure out what they tell the virus to do.

"Anywhere there's life, we expect viruses," Young said. "They are the major source of biological material on this planet."

Researchers said the virus and others found at Yellowstone will give researchers a hand in the search for life on other planets, including Mars.

"These bugs are living and doing business in a harsh environment," Rice said. "This may be clues about what to look for."

I would have asked the researchers how the virii got there in the first place; this writer didn't think of that.

It seems logical that the virus would have got there along with the organism it is associated with that lives there. However that organism got there is how the virus got there. Without that living organism the virus can't replicate and go on for long. The only think interesting about this virus is that it appears to be heat resistant and most viruses are quite heat sensitive.

Predictions aren't proof. Evolutionists have been predicting things for 150 years -- unfortunately most of it is pure speculation and untestable.

Did evolutionists predict uses for "junk" DNA, or DNA proof-reading?

Indeed some did. You don't think it was creationists that did the research to determine this stuff, do you?

I'd have to know what happened to "the soup", and the other problem is that viruses are usually very specific to their host --- no matter how much your dog sneezes on you, you cannot catch the same cold they have in most cases.

"RNA-world" says that cellular life formed as parasites in the soup and ate it. Before then, the whole pond (or whatever) was something like one big organism.

The viruses today have survived by specializing, even as have the cellulars. Everything today is thoroughly modern.

No idea, but if we didn't predict something (this morning's DOW or whatever), what does that prove?

Yes, but their careers are in ruins and they are out begging on the streets.

We ought to be up to our reading glasses in scientific articles. But we're not.

One of the joys of dealing with academics in general is that they've become so narrowly specialized that they have precious little idea of what's happening outside their own particular sub-sub-field. Not that this is anyone's fault in particular, that there are no more Renaissance Men these days - it's a hell of a lot of work keeping up with one's own field, let alone all the rest.

There are not thousands of scientific articles published each year - there are hundreds of thousands. Agricola indexes more than 800 journals dealing with agriculture and plant sciences alone. Ovid indexes more than a thousand journals in medicine and biomedical sciences. Ingenta - I've lost track, but they index 28,000 academic journals, so you can browse through and figure out how many of those are scientific journals. The IEEE INSPEC database indexes more than 3400 scientific and technical journals - to quote them, their database consists of "over 7 million bibliographic records and is growing at the rate of 350,000 records each year."

Most of it's flying under your radar, so you don't notice it - the vast majority of that stuff is not of interest to the vast majority of the human race, because it's not their particular specialty. But that doesn't mean it doesn't exist. Believe me, if you knew where to look, you would be up to your reading glasses - and way beyond - in scientific articles.

It proves that evolutionists and researchers have severely underestimated the complexity and incredible design of humans and animals for a long time now. If they would have approached their research with a different perspective, who knows what they may have discovered by now. Cures for diseases, etc.

Recently, a discovery was made where the scientists had originally dismissed a gene as an antifreeze-protein pseudogene (5a), but in reality it was crucial to the animal's survival.

Protein is not "junk"

I see in your story where a previously overlooked protein was discovered. What are you saying about pseudogenes and where is your source? Pseudogenes do not code proteins.

“The two proteins differ slightly in their amino-terminal sequence and amino-acid composition. At the time of its discovery, the 5a gene was dismissed as an antifreeze-protein pseudogene, largely because the protein it encodes would have been grossly different from type I AFP and had never been detected in the flounder”

So that is proof that scientists have been doing science wrong:

Acceptance of literal Genesis by Marshall and Fletcher would have led them straight to this elusive protein? How?

The "perspective" doesn't necessarily have to be "literal Genesis" - but it should be something other than "the body is full of useless relics of the past" (i.e., "junk"). If their going-in position(s) had been "this must have an obscure, or yet to be discovered function" - then perhaps science would have progressed further, faster.

And yet it progressed, despite their dismissal of design.

When billions of taxpayer dollars are being funneled into research programs, and thousands of scientists are out there utilizing the latest and greatest equipment available - of course they are going to *stumble* across things like this.

However, since most scientists accept billions of years and thousands of beneficial 'accidents' as being responsible for themselves - what's a few more years in waiting to discover another use of a perceived piece of "junk?", eh?

"Stumble"? Do you have anything to support that characterization, other than your own fevered imagination? Because it sure looks like the result of a deliberate investigation to me. And when exactly was the 5a gene in the winter flounder first described, anyway? Do you even know what the rationale was in calling them pseudogenes in the first place, or are you comfortable - as apparently you are - in inventing your contention that it was simply assumed to be a pseudogene by the original investigators? Did you even bother looking up the work of the people who first described 5a, or does that crystal ball of yours obviate such mundane gruntwork?

How can you be so blind to the flood of new pharmaceuticals, medical techniques, cures, and agricultural enhancements flowing from the productive minds of creation scientists?

Must you always attack "Creation Scientists?" I don't even know one. I don't even know if there is such a thing. There are a number of scientists who believe in God - many have patents. Are you suggesting that only Atheists make discoveries?
