How DNA Repairs Can Reshape Genome, Spawn New Species
Science Daily ^ | Aug. 14, 2008

Posted on 08/14/2008 1:45:15 PM PDT by Soliton

Researchers at Duke University Medical Center and at the National Institute of Environmental Health Sciences (NIEHS) have shown how broken sections of chromosomes can recombine to change genomes and spawn new species.

Isn’t this what used to be known as “mutation”?

Read the article not sure exactly what it is trying to say.
But whatever it is it is just a scientific theory. If they actually ever have it to happen let me know. Just like “our ancestors were monkeys” Darwin did not even believe that as he wrote it.

Does DNA need to be broken before you repair it?

This is very nice.

Now if it would just happen at the same time, and the same place, in the same manner, to two members of the same species, but opposite in sex, then maybe they could produce offspring. But it doesn't seem very likely, does it?

Now I can understand the evolution of the typical liberal moron, it isn’t their fault. They just had some DNA damage.

Just a scientific theory?

Tell me, then, since you are so erudite in matters of science, what is better, or at a higher level of verification, than a "theory?"

A theory is not a proven fact.

In common usage, the word theory is often used to signify a conjecture, an opinion, a speculation, or a hypothesis. In this usage, a theory is not necessarily based on facts; in other words, it is not required to be consistent with true descriptions of reality.(like global warming).............. An opinion, a speculation not a fact. For example I could have a theory that all conservatives believe in the bible. But with out proof from point a to point b, I am just speculating. Just as the libs try to say alternative cars can be reality in 10 years is a theory not a fact.They have no proof. If you have no proof that you evolved from a monkey then it is just theory.

You would be correct if laymen were doing science and writing the textbooks. They are not.

Science defines the terms it uses very carefully, and the imprecise usage of laymen is of no consequence to scientists.

In science, a theory is as high a level of documentation as you can get. It is not a guess, or an opinion, or a speculation, or an hypothesis. Those terms are all defined differently (see my FR home page for definitions of all of these terms).

From my home page:

Theory: a well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena; "theories can incorporate facts and laws and tested hypotheses." Addendum: "Theories do not grow up to be laws. Theories explain laws."

Theory: A scientifically testable general principle or body of principles offered to explain observed phenomena. In scientific usage, a theory is distinct from a hypothesis (or conjecture) that is proposed to explain previously observed phenomena. For a hypothesis to rise to the level of theory, it must predict the existence of new phenomena that are subsequently observed. A theory can be overturned if new phenomena are observed that directly contradict the theory.

When a scientific theory has a long history of being supported by verifiable evidence, it is appropriate to speak about "acceptance" of (not "belief" in) the theory; or we can say that we have "confidence" (not "faith") in the theory. It is the dependence on verifiable data and the capability of testing that distinguish scientific theories from matters of faith.

In brief, a theory is the current best explanation for a set of facts. It has been tested and passed those tests, and it has successfully made predictions. It is far from a layman's guess.

That the layman's definition of theory might include guesses and opinions has no bearing on how scientists define the term, and how scientists construct theories.

Oh, and its proof you want? Here's what my home page has to say about that:

Proof: Except for math and geometry, there is little that is actually proved. Even well-established scientific theories can't be conclusively proved, because--at least in principle--a counter-example might be discovered. Scientific theories are always accepted provisionally, and are regarded as reliable only because they are supported (not proved) by the verifiable facts they purport to explain and by the predictions which they successfully make. All scientific theories are subject to revision (or even rejection) if new data are discovered which necessitates this.

Proof: A term from logic and mathematics describing an argument from premise to conclusion using strictly logical principles. In mathematics, theorems or propositions are established by logical arguments from a set of axioms, the process of establishing a theorem being called a proof.

The colloquial meaning of "proof" causes lots of problems in physics discussion and is best avoided. Since mathematics is such an important part of physics, the mathematician's meaning of proof should be the only one we use. Also, we often ask students in upper level courses to do proofs of certain theorems of mathematical physics, and we are not asking for experimental demonstration!

So, in a laboratory report, we should not say "We proved Newton's law" Rather say, "Today we demonstrated (or verified) the validity of Newton's law in the particular case of..." Source.

Note that that last definition is not something I just made up. Its from a CalTech website.

Your words………
A theory can be overturned if new phenomena are observed that directly contradict the theory.

· When a scientific theory has a long history of being supported by verifiable evidence, it is appropriate to speak about “acceptance” of (not “belief” in) the theory; or we can say that we have “confidence” (not “faith”) in the theory. It is the dependence on verifiable data and the capability of testing that distinguish scientific theories from matters of faith.
My thoughts……..
I guess we are still sharing thoughts about The Theory of Human Evolution. If not please let me know. Where is the “verifiable evidence”. Using your own words from above a theory is not a fact. Since you have your on homepage you must be involved in science, I am not.
Just because a group of scientist get together and accept a theory that all species came from one organism, that does not make it fact. There are also a group of scientist that do not believe the theory is correct. Which theory is fact?
Just as one group of scientist believe in global warming and another does not. As I said in my early post Darwin in his writings wrote of his disbelief in his own theory. Believe what you will but I do not believe in the theory of human evolution. When you get the proof let me know.

My thoughts…….
Human Evolution can not be proven or demonstrated!

You seem to be arguing from religious belief rather than a knowledge of evolution, and your post has quite a few scientific errors.

I don't have time to point them all out to you. I have done this over and over with new posters. Most simply ignore the evidence.

And you are right, I am familiar with science. I studied evolution, fossil man and a lot of related subjects in graduate school for six years. That was a while ago, but the evidence has only grown stronger since then.

The fossil record made an almost airtight case for human evolution, but genetics sealed the deal. You should check out some of the evidence; you might be surprised by what you find.

Ok so you have all those years of study and you immediately begin to guess that I am not agreeing with you because of religious beliefs. I have yet to say anything about my religious beliefs or ask about yours. I simply bring to thought that you have scientist that do not believe in the theory (I choose to side with these) and you have some that do (you choose to side with them). I will not attempt to discuss small details of the theory with such a scholar as you. But I am allowed to read and make my own choices just as you were allowed to attend class for all those years and agree with your professors on the matter. So I guess we will have to agree that we disagree.

You have mirrored some of the same arguments I have seen used here for several years by religious believers, so I assumed you were coming from the same general orientation as they were.

I suppose you mean your tagline.
(Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.)

So you are assuming that the only reason someone such as myself could disagree with someone with such education as you and others like you is because of religious beliefs.

To this I reply, not all scientific evidence/theory produces proven/demonstrated fact. They are only theories that may or may not be proven one day.

Again we will have to agree to disagree.

Please go back and read the post I made to you discussing the role of theory in science. I took some time and effort to explain how theories work, and in spite of that you are still making the same low-level mistake of expecting a theory to be proved.

Unless you have some familiarity with how science works, you have no business imposing your expectations on it, particularly when they are incorrect.

____________________________________________________

Read it again, it is still just a theory.

And by the way I am not imposing my expectations on anything or anyone. It sounds as if you wish to impose your expectations/beliefs on everyone that does not agree with you. So do not waste anymore of your time on me because I do not/will not agree with you on human evolution.

Have a great day!
