  1. Where did matter come from?


    John Harshman:

    I just believe whatever the cosmologists tell me. Not my department.


    Daniel Harper:

    Is there a cosmologist in the house?

    No seriously, there are several ways philosophers can answer these types of questions; non-Christian theologians were doing it centuries before Christ. Ever read the pre-Socratic philosopher Parmenides? If ancient philosophy about the nature of reality's your thing, it's hard to beat him until you get to Plato. Read him for interesting material on the nature of reality, and its differentiated nature today. It's pretty fascinating stuff.

    Modern philosophers, of course, rely on modern science to tell them about the beginnings of the universe, and basically concur with science when it tells them that the universe had a definite beginning some fifteen billion years ago, for an unknown reason. While many theists take this to affirm the existence of God, it's also not clear what kind of substrate the early universe existed in, i.e. whether what we now know as "the Universe" is only a temporary bubble in an eternal "higher universe".


    Sverker Johansson:

    I'm not a cosmologist, but I play one while teaching.

    Matter "condensed" from the original high-energy primordial radiation soup that filled the early universe. At high energy, there's an equilibrium between creation and destruction of matter -- but as the temperature drops, the energy eventually gets too low and matter drops out of equilibrium, leaving a residue of stable matter.


    TomS:

    Additional points:

    1a. What is the anti-evolution explanation for where matter comes from? (This will be a recurring theme in my additional comments, to point out that it is not merely enough to say that "theory X does not explain observation O" -- "theory Y" should do a better job of explaining O.)

    1b. The question of the origin of matter is not something that evolutionary biology treats. You might as well argue against the periodic table of the elements, or universal gravitation, by asking, "but where did the matter involved come from?" (This will be another repeating theme.)



  2. How did life suddenly appear from nothing?



    John Harshman:

    Who says it did? We know little about the time frame for the origin of life. It's often claimed that it couldn't have arisen earlier than about 4bya, because cosmic bombardment was too intense till then for there to be a solid surface on earth. And the oldest indications that life might have been present (chemical fossils of a sort) are around 3.8bya. Even if we believe those two numbers, that allows 200my for the origin of life. Where did you get the "suddenly" and "from nothing"?


    Daniel Harper:

    Life did not "suddenly" appear; it almost certainly took some time for early chemicals to "evolve" (loose terminology here) until they could self-replicate, and it did not appear "from nothing" in that life seems to have arisen from chemical reactions of some sort or another in existing materials on Earth at that time.

    As a biochemist about the details, but rest assured that science has some pretty solid guesses about the process by which non-living chemicals increased in complexity until they became self-replicating "lifeforms". Of course, the exact point at which "life" is separated from "non-life" is fuzzy; perhaps you could give us a solid definition before we attempt to answer your question further.


    TomS:

    2a. Once again, what does anti-evolution have to say about "how did life suddenly appear from nothing?" Please note that word "how". To say that "God made life" most assuredly does not say "how" this happened. When I say that we don't know how God made life, that does not deny that God made life, it's only pointing out that we don't know how.

    2b. And, once again, evolution does not (at least at the moment) treat the origins of the first life. No more than chemistry treats the origins of the first chemical elements. Evolution is about what happens in the world of life on earth, just as chemistry is about what happens to the world of elements.



  3. How does the evolutionist know that there is no God?



    John Harshman:

    You are confusing evolutionary biology with atheism. Some evolutionary biologists are atheists, some are Christians, and some are all sorts of other things. This question makes no sense.


    Daniel Harper:

    Evolutionary biology neither affirms nor denies God; it attempts to explain physical processes available for study on the Earth. Thus, many (even most) of those who accept evolution as the truest explanation for life's existence on this planet also accept some sort of God. (As I do, personally.)

    Also, and this is just semantics, your question is poorly worded from a logical standpoint; you seem to be denying that God exists, but asking how an "evolutionist" could possibly know it. A better way of phrasing this would be, "Why do evolutionists believe there is no God?" but even then you are committing the fallacy I exposed in the paragraph above. Better to not even ask the question, or else to use the word "atheist" instead of "evolutionist", since evolutionists can, and many do accept evolution.


    TomS:

    Many people of faith in their Creator, Sustainer and Redeemer accept the evidence and reasoning behind evolutionary biology. I can point to a couple of web sites which may be of interest to the person of faith who is concerned about this:

    This is an interview with Bob Bakker, who is a famous dinosaur paleontologist and a pentecostal preacher:

    <http://www.prehistoricplanet.com/features/articles/bakker/index.htm>

    This is from the web site of Christian Schools International:

    <http://community.gospelcom.net/Brix?pageID=2831>

    Finally, the famous evolutionary biologist Theodosius Dobzhansky wrote a number of years ago a famous essay entitled, "Nothing in Biology Makes Sense Except in the Light of Evolution". Dobzhansky was not only a major figure in evolutionary biology, he was also a Russian Orthodox. You may note that in this essay, he says, "I am a creationist and an evolutionist":

  4. What is wrong with a creationist saying, "By faith, I believe that God created the universe" when an evolutionist says "By faith, I believe that the universe created itself"?


    John Harshman:

    I doubt the opportunity would ever arise, because I've never heard an evolutionist say that. However, there's nothing wrong with a creationist saying anything he wants, or believing anything he wants by faith. The problem arises when a creationist wants to push his ideas as if they were science, or have them taught as science in public schools.


    Daniel Harper:

    I used to be an atheist, and would never have phrased the question in that way. First of all, the same argument about "evolutionists" cited above would help clarify matters here; many of those who accept current scientific theories about the origin on the universe are also theists and Christians. Secondly, it is illogical to argue that something can create itself, whether it is the universe, God, or a chocolate cake. Thirdly, atheists do not believe the universe lies uncreated by faith, but because there is no direct evidence of a creator who has done the creating. I know many atheists; if confronted with hard evidence of God's existence, I have little doubt that most of them would accept that evidence willingly and gratefully.


    TomS:

    See [my] preceeding points.


    Jon Fleming:

    This looks like an attempt to cast science as religion.

    It's worth noting that the 'evolutionist' does not say "By faith, I believe that the universe created itself'; the 'evolutionist' says something like "The best and simplest explanation of the known evidence is that the Universe was created <insert appropriate explanation here>".

    Of course there's nothing wrong with a creationist saying "By faith, I believe that God created the universe". However, there's a lot wrong with saying "My belief that God created the universe is scientific, and I want it taught as science in U.S. public schools" without providing appropriate evidence. The latter is encountered far, more often than the former.



  5. Wouldn't creatures produced from chance have random thoughts?


    John Harshman:

    Would this question be a case in point? Given this list of random thoughts, I find the inclusion of that question pretty funny. But nobody says we resulted from chance. Natural selection is not random.


    Daniel Harper:

    "Chance" is only half the equation of evolution. "Natural selection" is the other half. Natural selection "selects" for those variants that have the highest survival value; those organisms whose thoughts most closely match reality likely have a significant survival value over those whose thoughts do not.

    This question leads me to believe that you have little understanding of evolutionary biology. Perhaps a textbook would help?


    TomS:

    5a. "Wouldn't designed creatures have designed thoughts?"

    5b. This is properly a question about genetics and developmental biology, not evolution. Our genes are a chance mixture of the genes from our parents, with some additional random mutations. If you are concerned about the consequences of chance, you should be addressing your concerns to these sciences.

    [I won't respond to] the rest because I think that you should understand the general drift of what I am getting at. These questions have two general problems: (a) they don't present an alternative which has any better answers than generally accepted science; and (b) they are arguing, not with evolutionary biology, but with some other science.

    I will leave the scientific responses to the scientists.


    John Wilkins:

    [...] Anything that results from chance is as law-bound as anything else (especially since "chance" is subject to the laws of variation and error anyway, and what these folk call "chance" is really physically deterministic processes anyway, such as mutation).


    TomS:

    And the standard example of a very determined result from very chance events is that a casino will make money. They will try their best to make sure that the events are (from the point of view of the gamblers, at least) chance events. If they are not chance events (such as when someone gets a system for beating the house), then the house can have troubles.



  6. How can 'chance' create anything anyway?

    Chance is only a term we use to simplify complex mathematics.



    John Harshman:

    Chance doesn't create anything. Natural selection is not chance. And there are various other order-creating natural processes too, none of which can be called "chance".


    Daniel Harper:

    Your second sentence is a bald assertion that needs to be supported to be accepted. Quantum mechanics, for instance, seems to show us a world that is "random" at its very core; does it make sense to argue that we simply have no devoloped mathematics complex enough to deal with it?

    Your first sentence suffers from the same problems I mentioned above; you seem to have no understanding of evolutionary biology. Evolution procedes by two basic steps: mutation adding to the gene pool, and natural selection weeding out those organisms who are less fit than those around them. Chance, as you are using it. only applies to the first half of the equation. (Unless, of course, you'd like to argue that the laws of nature are themselves random, in which case you're farther gone than I believe you are.)


    John Wilkins:

    "Chance" used to mean, before QM, that we simply didn't have enough information to make a prediction - this is the Laplacean sense of chance. This is the only relevant sense it applies in evolution, apart from the fact that a mutaiton of genetic combination is "random" in the sense that it did not arise in order to serve some purpose - that is, mutations, etc., are random with respect to the functional needs of organisms.


    TomS:

    I thought that your final sense of "chance" was the traditional phiosophical usage of the word. Perhaps going back to the time of Aristotle? The standard example that I recall is of someone going to the market, and meeting someone by chance. We might be able to determine the reasons that I and the other person went to the market, but those reasons did not include "so that we can meet".

    And I thought that that was the important sense of chance in evolution. Even if we could determine precisely what genetic mutations and combinations will take place, what determines those changes is not the evolutionary outcome. (That is, I am carping about your saying "This is the only relevant sense .. apart from ..."I would reverse that, to say, "The only relevant sense is that the changes do not serve some purpose, apart from the other sense, that we cannot determine what changes will occur.")



  7. Why does man seem to have a need for religion?


    John Harshman:

    A good question. I think the answer you are looking for is that this somehow means that god created it. But which god? Krishna? Zeus? Jehovah? Whatever the reason for the need, it seems to be filled in hundreds of mutually contradictory ways, some of which (like some forms of buddhism) don't even incorporate a god at all.


    Sverker Johansson:

    Some do, some don't.


    Daniel Harper:

    Just because man has a need for religion (which many people I know don't seem to have, or at least have in a much lesser degree than many others) does not mean that God exists. If God exists, He would probably instill in his creations a need to express themselves to Him, which would lead to a growth of religion, but you can't argue the other way around.

    If I have a bill for X dollars come in the mail, does that mean that I must have at least X dollars in my checking account? Of, if only that were so....



  8. Why haven't monkeys produced at least some of the paintings that we find from almost every primitive human culture?


    John Harshman:

    It seems to have been a fairly recent development. In fact, painting doesn't seem to have happened until around 40,000 years ago. It's clearly a cultural development. You may as well ask why monkeys don't have bows or cook their food too.


    Sverker Johansson:

    Apes do paint when provided with paint and paper and brushes, in a human-cultural setting.


    Daniel Harper:

    Well, first of all, there are indeed monkeys who can paint better than I can, I'm sure. Monkeys have been trained to express themselves artistically; they do seem to have the ability to learn such talents.

    If you're asking why monkeys are not humans, I'd answer that sea horses aren't humans either; humans also are not sea horses. We can't breathe underwater and swim sideways; does that imply that evolution is not true?

    To get to the nitty-gritty of your question, it's also almost certainly true that monkeys simply don't have the intelligence of humans (not to mention the free time that tool-making provides), which goes a long way towards explaining why monkeys haven't developed cave painting yet. What does any of this have to do with evolutionary biology, anyway?



  9. Why is there order everywhere as opposed to chaos?


    John Harshman:

    I don't know. But why should chaos be the null hypothesis anyway? Order comes about from a wide variety of possible sets of rules. Is chaos more likely than order when a universe comes about? What is the possible parameter space, and how much of it results in order rather than chaos? I don't know, and neither do you.


    Daniel Harper:

    Define "order" and "chaos" and I'll get back to you.

    It should be noted, while I'm here, that Quantum Mechanics holds that at the bottomost level of existence, reality does seem very random and chaotic, and that only statistical averages observed on a day-to-day basis on the macro scale belie any "order" to the universe. Perhaps this is overstating my case, but you really haven't defined your terms very well.
