    I guess the cost is that they would be forced through a genetic bottleneck were a sample group of them ever transplanted to an environment that pushed for lighter skin. With all the genetic code for both light skin and dark skin it would be simple to adapt to one extreme by dropping off the information for the other. But a return to the original environment could never see them regain all that lost genetic code.

    Not sure if my biological terminology is correct and I'm sure it's a bit more complex than that, but the simple point is that entropy ensures that there will be a cost. I can be certain it exists whether or not I have an idea of what it might be.

    I can also be certain that if we are talking about genetics then the cost exists in a genetic medium rather than in sunlight.

    Make it support evolution and your nobel is guaranteed.

    I don’t know what “this observed trait is”. If you are speaking of entropy, then it is not an observed trait common to both fields, anymore than showing fear (to quail) is the same as eating a type of bird called quail.
    Do you think he would be interested in addressing the challenge as it now stands?
    I have no idea where Styer’s future interests lie. E-mail him and ask.
    I do tend to lump you guys together a bit, don't I. Apologies.
    Apology accepted. Johnny reminds me of some of my colleagues, great guys who honor their faith yet are not afraid of doing honest science.

    Bob was KO’d - but is asking for a tie

    Win or lose in this One-on-One debate should be on the debate subject. The problem is, the specific question to be decided is not declared external to the debate, but has to be inferred from the opening post.

    After presenting some preliminaries, in referring to Styer’s paper Enyart asserts:
    But the paper repeats an error that Henry Morris made fifty years ago,
    which error Enyart goes on to say is that of conflating the two definitions of entropy. In his OP Enyart relies on claims by Timothy Stout, and then talks a bit more about entropy confusion. But nowhere in his OP, other than by saying it is so, did Enyart show that Styer mixed up the disparate definitions of entropy. That is the challenge of this debate – did Styer cheat by relying on two different concepts of entropy?.

    Enyart has shown that the confusion over entropy exists in both the evolutionist community and the Creationist community. The thing that he has not done is to show that Styer was confused, or that Styer relied on that confusion in the larger community to establish his point.

    Enyart has faulted Styer for not being hyper-explicit about saying that his use of the word “entropy” referred to thermodynamics. Yet, as Johnny showed, both in Styer’s opening sentence and continuing throughout the paper, he is speaking of Thermodynamics.

    Styer’s analysis discrediting thermodynamic entropy as a barrier to evolution is untouched by Enyart’s repeated efforts to show that Stryer relied on a confused definition of entropy.

    And note that in his One-on-One post of Dec 14 Enyart includes an offer for Johnny to concede in the title of his post, but in the body of his Dec 16 post he has lowered his sights and is now asking for a tie. Wonder why?

    Notes on Entropy and Evolution

    On 5 December 2008 Bob Enyart said that my paper on "Entropy and Evolution" claims that


    evolution on earth can appear to violate the 2nd Law locally because a decrease in entropy as a squid evolves in the sea is offset by a fluctuation of entropy in a galaxy far, far away.


    In fact, I never said this, nor anything like it.

    1. The phrase "to violate the 2nd Law [of thermodynamics] locally" has no meaning. The second law says that "heat flow is from high temperature to low temperature" -- the notion of "local" doesn't appear in the second law.

    2. I have never in my life used the term "fluctuation of entropy" because I've never understood what it meant.

    3. My paper shows that the decrease in entropy as a squid evolves in the sea can be offset by an increase in the entropy of the microwave background. The microwave background is not "far, far away" ... it's right here. We're immersed in it.

    ====================================

    Bob Enyart goes on to say


    Entropy is NOT a manifestation of the 2nd law of thermodynamics.

    It is not.

    The reverse is true.

    The 2nd law is a manifestation of entropy.


    Notice that Bob just states this claim with no supporting evidence.

    There are a number of different approaches to entropy, but the historical one is to begin with the second law -- "heat flow is from high temperature to low temperature" -- and from it derive the existence of entropy. (This derivation is long and subtle, and is perhaps the most beautiful piece of logic I've ever encountered. If you haven't seen it, I recommend Fermi's old and very clear book Thermodyamics.) As such, entropy is not a "manifestation" of the second law of thermodynamics but a consequence of it. However, the word "manifestation" is unclear here, so I'm not entirely sure what Bob means.

    ================================

    Bob Enyart speaks long and hard about the difference between "heat entropy" and "information entropy". It is quite clear from context that by entropy I mean "thermodynamic/statistical mechanical entropy". A simple glance at the equations in my paper would have made that abundantly clear.

    ================================

    Bob Enyart goes on to say


    Entropy has to do with the move from order to disorder in any organized system, whether it is organized by energy states, ergonomics (arrangement of utensils in your kitchen, etc), aesthetic values, information content, etc.


    This is very false. My paper "Insight into Entropy" (also in American Journal of Physics) is devoted to overturning this misconception. Frank Lambert has also devoted considerable energy (in the non-physics sense of the word!) to the same end. See

    http://www.entropysite.com/

    (By the way, Bob criticizes me severely for not distinguishing between "heat entropy" and "information entropy", but in the passage quoted above he does exactly the same thing!)

    What does entropy mean?

    Radio announcer Bob Enyart takes me to task for not distinguishing between "heat entropy" and "information entropy" in my American Journal of Physics article "Entropy and Evolution". Any knowledgeable person could just look at the equations in my paper and see that I mean "thermodynamic/statistical mechanical entropy".

    The word "entropy", like most words, has many meanings, and the meaning in use is determined from context. If I say "Run away from danger", you don't think "A run is a small stream, so I must follow a small stream away from danger".

    Here I want to present some of the other meanings of the word "entropy", to emphasize that it would have been silly to say that I'm not talking about each of them:

    information entropy

    topological entropy

    Kolmogorov entropy

    Kolmogorov-Sinai entropy

    metric entropy

    Gibbs entropy

    Boltzmann entropy

    Tsallis entropy

    von Neumann entropy

    Shannon entropy

    Rényi entropy

    volume entropy

    If I spend so much time talking about what I'm not going to be talking about, the paper would have been quite long indeed!

    Dan - fair warning. I think you have stepped in it now.

    One thing Reverend Enyart delights in is getting scientists with name recognition to respond to him. Long after you have left these forums, he will construe what you said the way he wants, with little regard for how truthful his portrayal is. Currently Enyart sells videotapes of where he goaded Michael Shermer (founder of Skeptics Society and frequent Scientific America writer) into a confrontation (over the phone, and during which Shermer finally just hung up in disgust). Similarly, he sells tapes of a telephone discussion with Eugenie Scott (head of National Center for Science education). I will be very surprised if he doesn’t similarly leverage your response to his liking.

    Enyart is the Christian equivalent of Howard Stern, and has cultivated an audience that thrives on his brand of confrontational theology. If you took the time to listen to many of his shows, you would hear him asking his audience to ferret out people who disagree with him, and have them confront him on the air.

    Perhaps before, but not now. Whether you like it or not, in authoring your seminal paper you have joined the ranks of a small cadre of very influential scientists in the Creationism – evolution debate. You paper is generating a lot of attention in many forums like this. It has passed out of your hands now.
