The kinds of questions that appear frequently change over time, and this FAQ is updated from time to time to address new common questions. The question you ask might be well suited for an addition to list. In the meantime, there are answers in several other places in the archive.
In brief, new information arises frequently in the genetic code. For more detail, you can also check out the following files in the archive.
- Apolipoprotein AI Mutations and Information; a straightforward example of new information arising from a mutation.
- A response to creationist claim number CB102: "Mutations do not add information".
There is also an excellent set of articles on information theory in relation to this whole debate that has just been added to the archive.

The Big Bang is not proposing something from nothing. It proposes that the universe has expanded over time from a state of extreme density. It's not an arbitrary idea, but the surprising conclusion of many lines of evidence.
There is no incorporation of a "from nothing" step. There are still many unanswered questions. Existing physics diverges to unbounded density and infinitesimal scale a finite time into the past. This is called a "singularity", which means a condition in which equations are divergent or ill-defined. This is not a condition in which there is "nothing"; it is rather a condition in which time and space are not the concepts we are used to and which we can handle with known physics.
There is no basis for dispute here with mathematicians; the mathematics used is perfectly fine. The trouble is simply that some common intuitions turn out to be a very poor guide to how the universe works. Even in simple experiments in a lab we can explore phenomena right now that conflict violently with intuition. But the phenomena are not in question; it is our intuitions that need to be revised.
For my thoughts are not your thoughts,
neither are your ways my ways, says the Lord.
For as the heavens are higher than the earth,
so are my ways higher than your ways
and my thoughts higher than your thoughts.
Is 55:8-9
We cannot figure out how the world operates by sitting back and thinking about what makes sense for us. We have to look and see, and be willing to be surprised, and willing to learn from what we see shown in the world itself. It is good to bear in mind that although we have learned many things about the universe, there is no assurance that we will ever get it all figured out.

If you want to see how real scientists define evolution then read "What is Evolution?". For a brief summary of the modern Theory of Evolution read "The Modern Synthesis". Once you realize that Kent Hovind has lied to you about the definition of evolution you will begin to appreciate why he doesn't even have much respect among Creationists.

Claims about carbon-14 in dinosaur bones have been made by creationists, but usually without sufficient detail to know what tests were done, how well protected the fossils were against contamination, and so on. You can get contamination in various ways, from ground water, bacteria, rootlets, and so on.
Fossil bone does not generally have carbon present at all, which makes carbon dating problematic. Most of the arguments relating to invalid dates refer to other kinds of material.
Fossils can sometimes have carbon. For dinosaur fossils such preservation is rare, and scientists are unlikely waste such precious material on a radiocarbon test.
This issue is likely to continue to appear. Radiocarbon dating is not perfect; and critics will continue to inflate the degree of imperfection, and focus upon the exceptions. What is lacking, however, is any consistent alternative model able to explain the vast bulk of results that show radiocarbon dating to be a useful and accurate technique.

After reading some utter BULLS*** on this creationist website I found, about dinosaurs and man living together - interspersed with 'believe in god or go to hell' - AND presented as absolute fact, I nearly pulled my hair out. This was from the new 'museum' in whatever state it was. Fortunatly, I found your site shortly afterward and feel much better now. I realize there will probably always be creationists who refuse to see 'the word of god' as anything but totally literal, but I'm hoping your site will inject a little sanity into the world. Thank you.

I was under the impression that Behe (I have not read his book) had proposed a competing theory, with testable hypotheses, to explain certain biochemcial processes. But instead, as a scientist, he simply picked a phenomena that has yet to be fully explained, although still explained much more so by evolutionary theory and experimental biology than I originally thought. Because we haven't fully explained it, everything else that has been explained is now irrelevent. It's even more disingenuous coming from a scientist than a fundementalist.
I do believe there are many "irreducible" complexities awaiting any scientist, but our job is to reduce those as well. To continue explaining that which has yet to be explained, and never to simply brush something off as unsolvable.
Thanks for having a great site, and keep up the excellent work.

Intelligent Design for unintelligent Americans
Far from decrying Intelligent Design, Australians should encourage Americans to adopt the teaching of ID theory instead of the theory of Evolution by Natural Selection.
This will lead to the evolution of a scientifically illiterate American population, meaning a decline in superpower status. This will allow the rest of the world to catch up.

As I read through your FAQ sheets to see what you have to say, I am getting the impression that most evolutionists are pretty impatient towards and scornful of people who believe in creationism in one form or another. That scorn comes across loud and clear in the editoral commentary aaccomanying the FAQ discussions.
This impatience and scorn is all too common coming from evolutionists. Of course, I realize that creationists have their own temper problems. But there are there are many books on Intelligent Design written in a calm, rational tone of voice that manage to get their points across without painting evolutionists as nihilistic pagans.
Here's my point and question. Why the anger? If evolution is self-evident and self-supporting then how is creationism even remotely a threat? A book on creationism should be no more threatening to a young person than a copy of Aesop's Fables. The evolutionist response to creationism is akin to that of a book banning. Wouldn't creationism be deselected from public discourse faster if its flaws were laid open for all to see in a public manner? If not, then maybe a strong case can be made that creationism has strong survival traits from generation to generation? ;)
Anyway, here's what I want to see: an explanation of evolution written in a friendly, non-condescending tone. Not begging questions or avoiding difficult topics. Specifically addressing the religious implications of evolution. Written with the assumption that a religious person is attempting to make an honest inquiry into a difficult subject. Written with a sense of compassion and patience that acknowledges that a sensitive area is being breached and that people should not be brow-beaten into submission. Maybe such a book exists. If so, I would love to know its title.

It really amazes me as to how blind evolutionist can be, you believe in bad science ther is no prooof of evolution it is hog wash pure and simple. I have seen both sides, your side is lacking and it sounds like you people are getting very desperate since you are loosing ground. You believe in evolution just because you want to and you would not dare beleive in God because that would make you face that you are a sinful fallen creature in desparte need of salvation. But hey that is you choice and man I am for choice arent you?

I have a problem that I have been thinking about for at least 3 years, and I still have not figure it out.... so I hope you guys can throw some light to this.
In your FAQ, you have
Q "Don't you have to be an atheist to accept evolution?" A "Many people of Christian and other faiths accept evolution as the scientific explanation for biodiversity, See..."
Just because some people of the faith think it is not a issue does not make it a non-issue. Likewise, it is not reasonable say that "since some Catholic priests are pedophiles and that the church are known to have tolerated their behaviour for a long period of time, the Catholic faith accepts pedophilia." What is the logical difference between this and your Q&A?
This is the exact reason why scientists with faith are routinely dismissed as non-believers by fundamentlists. In my humble opinion, this is a fair accusation. A believe system that revolves around an absolute entity such as christian god cannot be adaptable at the same time. At some point science and religion become plainly incompatible. An attempt to reinterpret religion to fit modern science is no more acceptable than an attempt to twist science to fit a particular religion viewpoint.
Response
Philosophers of science mostly conclude that science is metaphysics neutral, following the Catholic physicist Pierre Duhem [1914]. Science functions the same way for Hindus as for Catholics, for Frenchmen as for Americans, for communists as for democrats, allowing for localised variations that are ironed out after a while. However, science does indeed rule out various religious etiological myths (origin stories), and often forces the revision of historical and medical stories used in the mythology of a religion. And when cosmologies are given in ancient scriptures that involve solid heavens, elephants and scarab beetles, science shows them to be unqualifiedly false as descriptions of the physical world as it is observed.
In short, when religion and science conflict, if you want to retain any sense that science uncovers the world in some way, then so much the worse for religion. But that does not immediately make religion false. No elaborate system of ideas is so rigid that problems in one area immediately force a crisis of confidence. Christianity and other religions have been dealing with the problems caused by the unreasonable success of science for a very long time - evolution is no worse for religious belief than any other scientific success (for example, gravity or atomic theory).
A religious perspective that required its adherents to reject science is in trouble. But no religion has remained constant and frozen, ever. All religions adapt to social change, technlogical change, and of course scientific change. It may or may not be acceptable in your view, but it is inevitable, and it has always happened.

Tolerance is only a virtue in broader society. Science is neither tolerant nor democratic, and that is the way it ought to be.

fast math:
Raining 40 days > cover mountains up to 29 000ft (8 900 meters) above the sea level. 29 000ft(8900 meters)/40 days = 10 500 inches (222.5 meters) /day 10 500 inches (222.5 meters)/24 hours = 440 inches (9.25 meters)/hour 440 inches (9.25 meters)/60 minutes = 7 inches (154 milimeters)/minute 7 inches (154 millimeters)/60 seconds = 0,10 inches (2.57 millimeters)/second.
Aside from this flood story, the heaviest rains ever recorded in one hour were 181 mm. This means that the downpour during the flood were 50 times heavier than the heaviest downpour ever recorded. The heaviest 24 hour downpour in the US, in a 24 hour period was in Houston TX, where 43 inches fell in 24 hours, comparing with the 10 500 inches it fell in a 24 hour period during the flood, that's more than 244 times the rainfall in Texas.

It makes sense if every feature of an organism is the product of its history, but it doesn't make sense if you want to argue independent design with appropriate reuse of common elements. Unless, that is, you're willing to argue that the Designer is wasteful, incompetent, and lazy.

Why do you think this would perturb anyone? Darwin was a very smart man who had some great insights, but he isn't revered as a saint, and evolutionary theory has progressed to an amazing degree since Darwin (you do realize he wrote in the 19th Century, and it is now the 21st, right? Or do all of our far-future modern ideas blur together from your perspective in the 12th?)

why are you not citing the stunning finds resulting from the AVIDA experiment in digital evolution? AVIDA has shown a means by which irreducibly complex structures like the eye can evolve in stepwise fashion. AVIDA has shown this very process occurring in the lab, in a digital environment, with digitial organisms that spontaneously evolve the ability to do an irreducibly complex mathematical operation that's dependent upon prior adaptations that in themselves do not produce the skill. the AVIDA writeup was a discover magazine cover story, i believe back in february 05. full text here:

Clair C. Patterson produces accurate "primeval" lead isotopic measurements from minerals of the Canyon Diablo meteorite which contain very little (less than ten parts per billion) uranium. Meteorites provide the final solution to the puzzle, for they both are "rocks which formed at the same time as the Earth," and provide the important data which allows lead isotope computations to look back to the formation of the Earth.
I would be interested to learn how someone, without having been present at the occurence of the event, can be so absolutely certain that meteorites formed at the same time as the Earth, that they feel confident to use this belief to base their scientific argument on.
I could follow the above argument if it would have said: based on the assumption that meteorites formed at the same time as the earth....
But it doesn't. It states as fact that meteorites and the Earth formed at the same time. I am puzzled.
Response
The reader's question is answered a few paragraphs later, under 1956. Briefly, the whole-Earth isotopic ratios falling on the meteorite isochron indicates a common origin.
For Dr. Patterson's original 1953 calculation, though, he only assumed that meteorites without uranium retained the original Pb isotopic ratios of the solar system. Even at the time, that was known to be a solid assumption, because all iron meteorites had the same Pb isotopic ratios.

We do know the facts, though. We see evolution occurring. We see the results of evolution (in the molecular structure of organisms, for example). So we were there in the relevant way. But it is hard to explain this to those who do not wish to hear it.

Thanks again for a good site and the good thinking, from a creationist friend who, like all of us, doesn't have it all together -"Like iron sharpeneth iron, so does one man sharpeneth another" A good verse that applied to us all as we think, and test ideas, and listen. Mike Chouinard

On the Woodpecker's skull - it is indeed a wondrous structure. Read about it here.
On Wegener, you are right that the land bridges were a desperate attempt to explain biogeography, but they were only posited because the geologists said Wegener was wrong and continents couldn't move. In fact Wegener wasn't the first to propose it either.
On Hawking, if you can comprehend what he says, you are a better man than I. But his ideas are not directly of relevance to evolutionary theory, as evolution occurs some ten billion years after the events he is discussing (apart from black holes, and so far as we know, evolution has nothing to do with them, either).
On males, it is true we love to play in the mud, and watch insects. That is the basis of science. Quite a lot of females do, too. But on all other aspects of female motivations, I am fully in the dark.

It also turned out that the document emanating from Rabbi Schneerson was included in a multi-author book which receives an extremely critical examination and review here: http://www.talkreason.org/articles/challenge.cfm The review's description of the book shows that some other religious Jews take much the same view of evolution as Schneerson does, although the reviewer does say that the other authors' arguments are not quite as bad as Schneerson's.
Randall Wald's comparison of religious Jewish and Christian attitudes was explicitly extended to cover 'even the most extreme religious Jews I've heard of', but I think the evidence shows that, although it may well be generally applicable, it's not universally applicable.

I do have a question though...how did John come to select ND4 and ND5 as the sequences for this test? Was it a random selection or was there some other reason for selecting those sequences.
I read the post twice and did not see the reason mentioned, so I apologize in advance if I missed that detail.

"For what it's worth, I think that sexual reproduction evolved initially as an accident due to the diploid nature of the DNA material, and was conserved in later lineages, but I'm no expert." feedback/feb98.html
"There are advantages that come with sexual reproduction; and life forms have developed which use both sexual and asexual." feedback/sep03.html
"...you ask which came first, the penis or the vagina. The answer, of course, is neither. Most animals that reproduce sexually do not have either of those structures; others have both. Single-celled organisms that reproduce sexually may just have a single gene difference." feedback/may01.html
None of these responses even makes a serious attempt to explain the origin of the sperm and the egg. There are some references to other websites, but after checking these it was found that these websites had no explanation for how sexual reproduction evolved either. So it is correct to conclude that evolutionists have no explanation as to how sexual reproduction evolved, that it is merely a faith belief?
Cheers,

A short summary can be found at Brown University's site.
Nature Genetics has a collection of technical papers available.
Sexual reproduction is a modification of the mechanisms for cell division (mitosis) in which the chromosomes are not duplicated after division (meiosis). The resulting cell forms a gamete which then introduces its genes into another cell, or is the other cell. There are examples of all kinds of intermediate forms of sex from occasional sharing of small bits of the genetic component (plastids) among bacteria, through to complete sharing (conjugation), through to partial crossover of genetic complements, through to the most amazing array of lifecycles.
Margulis and Sagan, in their book What is Life? (pp137-139) say
This is also how cells acquired and domesticated our cellular organelles, such as mitochondria.Meiotic sex evolved in mitotic protocists [single celled organisms] long before any animal appeared in the record of life. ...
Meiosis is a variation on the theme of mitosis. Meiosis likely evolved in doubled cells that had already divided by mitosis. The first fertilization event probably satisfied an urge not to merge but to eat. This could have happened if the protist cannibals ate one another. Microscopists sometimes witness microbial wranglings in which a hungry cell engulfs a neighbor .... But the cells do not always digest what they engulf. ...
Once upon a time, we think, eating and mating were the same.
This is widely known. It is disingenuous in the extreme for creationists to say evolutionary theory cannot explain sex.
