Uncommon Descent Serving The Intelligent Design Community

Evolution is a Fact, Just Like Gravity is a Fact! UhOh!

In this week’s New Scientist, there is an article about gravity that deals with a string theorist’s reformulation of gravity as an entropic force. This reformulation describes gravity as an emergent property of space, time and matter, and NOT as a physical force itself.

Here’s a quote from the actual article:

Of course, Einstein’s geometric description of gravity is beatiful, and in a certain way compelling. Geometry appeals to the visual part of our minds, and is amazingly powerful in summarizing many aspects of a physical problem. Presumably this explains why we, as a community, have been so reluctant to give up the geometric formulation of gravity as being fundamental. But it is inevitable we do so. If gravity is emergent, so is space time geometry. Einstein tied these two concepts together, and both have to be given up if we want to understand one or the other at a more fundamental level.

The results of this paper suggest gravity arises as an entropic force, once space and time themselves have emerged.

I will simply add that my own musings on space-time, and on Einsteinian relativistic presuppositions, tells me that Verlinde is correct, and that he is only one step away (it is a rather giant step, however) from a great leap forward in our understanding of space, time and matter.

I don’t need to bring out all the implications of this for the Darwinian-ID debate. This theoretical finding throws gravity, as a fundamental force of nature, into question. So, if gravity is now to be understood as a phenomena, and not a “fact”, then what about Darwinian extravagence?

Comments
Jerry, “I was referring to the micro to macro evolution comment” Ok, fair enough. However, it’s important to point out that camanintx made the comparisons based on just genomic differences asking why one couldn’t have descended from the other. As in, are there that many morphological & other differences that known evolutionary processes couldn’t reasonably account for between what we find in the fossil record? Quoting you directly : “The incremental and somehow advantageous change from rodent to bat or lizard to bird should be in the fossil record” In this context regarding humans you’re clearly asking for evidence of fossils which are representative of being intermediary between certain apes and now H. Sapiens. This you admit exists, so question is then are these evidence of descent w/ modification at the macro level a clearly those exhibited aren't all the same species, so clearly some major changes were going on. “we use a definition of complex novel capabilities for macro evolution or something similar” Jerry, how would the progression of apes becoming more & more like modern humans over time be for this comparison? Surely, these changes are novel as they represent the increase in cranium & brain size, changes in morphology which becomes more & more evidently ‘human like’ & less ‘ape like’ would this suffice? If not why not? In terms of novelty, such increases in the size of a cranium wouldn’t be much different then asking for a group of theropods which had feathers to be related to those which later became the first primitive birds. I think to some extend the fossil evidence is indicative of what macro evolution aught to entail, never mind such DNA evidence like Human Chromosome 2 fusion.agentorange

"no evidence it ever happened" I was referring to the micro to macro evolution comment. I just read Dawkins who covers human evolution in fair detail. And lists all the fossils etc. That is not what I was talking about. I can see where it would be unclear. Just no macro evolution from micro evolution. And if you want to quibble, we use a definition of complex novel capabilities for macro evolution or something similar. Think eyes, flight, brains etc.jerry

"The difference between humans and chimps is only about 180 million base pairs. Since these examples illustrate that can and do change over time, maybe you can direct me to a mechanism that prevents the micro-evolutionary changes illustrated from becoming macro-evolutionary changes over thousands and millions of years." Just that there is no evidence it ever happened. Read Behe's The Edge of Evolution. Small changes do happen and things can change over a long period of time but so many new capabilities require more than just small changes that getting the new information for them seems out of range for natural processes. Also gene flow prevents major changes from happening and even with a widely dispersed species such as humans nothing has changed so why when they were confined to Africa and close to the Chimps were there no gene flow to keep them homogeneous. I can imagine some reasons but to just quote deep time is meaningless. It is more of an appeal to magic then ID is to an intelligence.jerry

Davem, #32 “successive incremental changes in groups of organisms from a common ancestor can lead to distinctly separate species.” The incremental and somehow advantageous change from rodent to bat or lizard to bird should be in the fossil record, but it is lacking. Nor is there the transformation from short to long necked giraffe. Out of all the animals in the world there isn’t a single example of incremental change in the fossil record. ------------------------------------- I suppose you have never heard of archaeopteryx, the bird that is more like a dinosaur, or Bohlinia, the giraffe with an intermediate neck length? And maybe you could explain exactly what incremental changes between rodent and bat you think should be present in the fossil record?camanintx

jerry, #29 Your examples are micro evolution and don’t make the cut. ------------------------------------- Out of the 3 billion base pairs in our DNA, two human individuals can differ by as much as a million base pairs. A single individual alone has about 170 mutations in their DNA. With over 6 billion individuals currently living, that is a lot of random mutation for natural selection to work from. The difference between humans and chimps is only about 180 million base pairs. Since these examples illustrate that can and do change over time, maybe you can direct me to a mechanism that prevents the micro-evolutionary changes illustrated from becoming macro-evolutionary changes over thousands and millions of years.camanintx

I presume you are referring to loss of information, or minimal incremental change, both already well covered by Behe. In any event, you are definitely talking about microevolution, which is my point precisely -- we have no basis to extrapolate grand Evolution from the trivial and obvious changes seen in microevolution.
They have observed how successive incremental changes in groups of organisms from a common ancestor can lead to distinctly separate species.
Really? You are again talking about microevolutionary changes and using a very minimal "species" definition. I would be very interested in any examples of "successive incremental changes" that produced any macroevolutionary change. Fact: there aren't any you can point to.
Extrapolating a theory of common descent from these observed facts is no harder than deriving Galileo’s heliocentric theory from Newton’s laws of gravity.
You seem confused about the analogy. How does gravity extrapolate to heliocentrism? In any event, back to the topic, the question is precisely whether the extrapolation of a grand evolutionary narrative from the paucity of observed facts is warranted. Simply stating that one can extrapolate isn't helpful -- that is precisely the point at issue. We can just as easily assert, as I will, that there is no good reason to think that we can extrapolate broader macroevolutionary changes from the observed microevolutionary changes. So far, it appears there is no evidence to support such an extrapolation, only that the theory needs it.Eric Anderson

It seems all their data for complexity arising is in computer programs and not actual genomes. You would think that genomes is where the action should be.
You may tell this the sciensists at the Biologic Institute and the Evolutionary Informatics Lab who are focussing on algorithms too.osteonectin

jerry:
I think several thousand have been sequenced. I believe there is a site someplace on the internet that keeps track of them. My guess is the software to analyze them and to compare them is what is at issue. Also I am sure there are many more partial genomes that have been sequenced. Nobody has reported anything earth shattering yet for all these sequenced genomes both whole and partial.
It surprises me that you "believe there is a site someplace on the internet that keeps track of them". Actually, these sequenced genomes should be at the heart of ID research and should be used as the main resource for anybody really wanting to do ID research. Unfortunately, neither the Biologic Institute nor the Evolutionary Informatics Lab went in this direction (to my best knowledge they didn't publish anything in this field). Currently, all sequencing data are assembled by programs that presume evolution as the source of biological information. And these programs run reliably as has been proven by molecular biological techniques e.g. FISH staining of chromosomes [not to be mistaken as your inner fish ;)], genomic southerns, radiation hybrid clones etc. again and again. It would be interesting to see what design theory could contribute to this field because there are some fields where better algorithms would be helpful. If ID would produce anything that could be proven in the wet lab reality the community would quickly adopt such techniques. Until then you may be more reluctant to convict 21st century biology.osteonectin

camanintx[21]: You're indulging in the very kind of rationalization I decry. You're giving a "know-it-all" answer. You think you know something and you know nothing. Read Verlinde's article and try to understand it. Here's what he says in the "Conclusion and Discussion" section: (This is the very first paragraph.)
Gravity has given many hints of being an emergent phenomenon, yet up to this day it i still seen as a fundamental force. The similarities with other known emergent phenomena, such as thermodynamics and hydrodynamics, have been mostly regarded as just suggestive analogies. It is time we not only notice the analogy, and talk about the similarity, but finally do away with gravity as a fundamental force."
Do you get it now? Gravity is, as I've stated above, an "epiphenomenon", not a real, fundamental force. Rather, it is a byproduct of a different kind of physical architecture; that is, the net result of "entropic forces" (which are microscopic and involve "degress of freedom", none of which involves "mass", except for its effect on these degrees of freedom). This means that the whole way of thinking about gravity must change. Yes, apples still fall in "perpendicular lines" to the earth, as Newton noticed, but the "force" he associated with those "perpendicular lines" really doesn't exist---just as Darwinian evolution doesn't exist, although the fossil record shows a progressives "evolution" of forms. But happy rationalizing! I'm sure you're not going to want to change the way you think about gravity or Darwin. And, in this, truth suffers.PaV

"I’m sure they can find these themselves." Your examples are micro evolution and don't make the cut. I do not know how many times the nylon example has been brought up but it is irrelevant. ID doesn't question changes like these. That you brought them up here, means you don't have anything. So I take back my suggestion and that you should not contact Dawkins or Coyne. You are no better off than they are.jerry

Eric Anderson, 22 Sorry, but you must be *way* more specific than that. I am aware of many different ways the word “evolution” is used in the literature, ranging from the obvious and well-observed to the outrageous and wildly-speculative. For example, if all you mean is that nature isn’t forever static, then big deal — and we don’t need Charles’ theory to help us there. If, on the other hand, you mean something much more grand (and controversial), such as abiotic origins, descent of man, universal common descent, etc., then you have no “fact” to point to — it is still theory. ----------------------------------- It's really not that complicated. The Theory of Evolution is based upon mechanisms derived directly from observed facts. Researchers have observed organisms gaining new functions through random mutation and natural selection. They have observed how successive incremental changes in groups of organisms from a common ancestor can lead to distinctly separate species. Extrapolating a theory of common descent from these observed facts is no harder than deriving Galileo's heliocentric theory from Newton's laws of gravity.camanintx

There is simply no comparison between evolution and gravity in terms of their factual content, specificity, or predictive capabilities. Gravity is observed literally every moment of every day; we can measure very precisely how planes and rockets will react at any given distance from the earth; we can send men to the moon and ships to the outer planets. Sure, there are some very interesting nuances about exactly how gravity works, and we probably have much to learn there. But for someone to suggest that evolution (whatever that slippery term means) is as well an established fact as gravity is more than ludicrous, it is laughable.Eric Anderson

PaV, #20 When an argument is presented as being the strongest of arguments, and then this argument is shown to be suspect, to simply go on as if it’s no big deal reeks of rationalization. When that happens, truth suffers. ------------------------------------- Newton's theory of gravity became suspect in 1859 when Mercury's orbital precession was found to differ from what the theory predicted. Despite the advent of Einstein's Theory of Relativity, Newtonian physics is still taught today because it is foundational. Has truth suffered because of this?camanintx

PaV, Of interest,,, The Physics of the Small and Large: What is the Bridge Between Them? Roger Penrose Excerpt: "The time-asymmetry is fundamentally connected to with the Second Law of Thermodynamics: indeed, the extraordinarily special nature (to a greater precision than about 1 in 10^10^123, in terms of phase-space volume) can be identified as the "source" of the Second Law (Entropy)." http://www.pul.it/irafs/CD%20IRAFS%2702/texts/Penrose.pdf That statement was from a paper in which Penrose was trying to find a bridge between quantum mechanics and gravity,,,,and tends to agree with Verlinde's statement:
The results of this paper suggest gravity arises as an entropic force, once space and time themselves have emerged.
,,, After a bit of reflection,, I think there is much promise in his "holographic" model for more precisely elucidating the required "non-material" explanation for gravity, or at least for elucidating how space-time curvature precedes as well as is primary and dominant of "material" gravity. i.e. His model seems to be "primed" to account for "dark matter",,, and indeed his model may also be found to explain dark energy as well if he can find a congruent entropic measurement for Dark Energy, which at first glance should be so since Dark Energy is "expanding" space-time itself.bornagain77

It will be titled, Evolution: The Extended Synthesis. “The word ‘extended’ is important because it implies quite clearly that there is no rejection of the previous synthesis,” Pigliucci says. “There is no rejection of the Modern Synthesis. There is no rejection of Darwinism. It’s an extension of it—we think a significant extension in a lot of different directions which neither Darwin nor the Modern Synthesis could have possibly thought of.”
This doesn’t exactly support your belief that that population genetics (= to Modern Synthesis, more or less) is “a complete waste of time”.
Of course it does not reject Darwinism because variation and selection do happen. See malaria resistance, for example. So Darwinism is part of the extended synthesis because it does do things. They just need to conjure up a natural way to produce complex, specified information. So Darwinism and the Modern Synthesis should make up around 0.001% of the Extended Synthesis - at least as far as the production of new information is concerned (it does a great job preserving what is already there). Hence the phrase "significant extension" - if Darwinism were the main driving force behind biological novelty, an extension wouldn't need to be labeled "significant". So as for the origin of life and species, yes I would comfortably say that population genetics is a waste of time.uoflcard

Eric Anderson: I share your same concerns. REC: bornagain is not a troll. And his posts don't usually have this same kind of content. He's a valuable contributor here. bornagain: The ideas you're expressing are similar to mine. I have a definite notion of how some of physics can be reinterpreted and have started to pursue it a bit. It could prove to be very interesting. And....it would have theological implications, though that is not the starting point of my reflections. Retroman: Two points: (1) The argument is routinely made that evolution is a "fact" just like gravity is a "fact". This argument is meant to say that evolution is, in fact, unassailable. (2) The counterargument has always been that there are several ways to consider evolution. For example, there is the fossil record. There are "breeds" that can be formed, thus indicating plasticity of phenotype. And then there is the explanation given for all these phenomena, which is itself called "evolution". And, so, while obviously observing the phenomena, we can still reject the explanatory cause given. Our critics arrogantly reject this counterargument. Verlinde's treatment of gravity shows just how arrogant---and unscientific---our critics have been. AND, further, they have sought refuge on this island of surety, and that island is being shaken to its roots. Verlinde's interpretation of gravity is not a force at a distance like Newton, nor is it, exactly, a curvature of space like Einstein, but rather has to do with the characteristics of space itself, and, specifically, its many degrees of freedom coupled to its ultimate discreetness. So, the explanatory core of gravity has changed---radically; something our critics would have laughed at us about should we have proposed it. It's now our turn to laugh at their arrogance. ALL theories are ultimately hypotheses that have, at the moment, grounds for acceptance. But that can always change. And science has a history of theories coming and going. But NOT Darwinism. So what if his theories are 160 years old. So what if the "co-founder" of natural selection ended up in disagreement with Darwin. So what if the Modern Synthesis is completely incapable of explaining what we find in nature. No matter---the theory lives on. A little humility, I think, is now in order.PaV

PaV, #6 And, please, tell me how you feel about the argument that has been made by so many for so long; namely, evolution, like gravity, is a fact. Well, the chair has been pulled out of that one. It really is quite an embarassment for the Darwinist side–or, at least, it should be. --------------------------------------- There is the fact of gravity, that things fall when I drop them, and the Theory of Gravity, that things fall because masses attract each other. There is the fact of evolution, that populations of organisms change over time, and the Theory of Evolution, that these changes are explained by random mutations and natural selection. Darwin's Theory of Evolution was certainly not the be-all and end-all of evolutionary theory just as Newton's Theory of Gravity was not the last word in physics. Modern Synthesis and Extended Synthesis no more discard RM & NS as a process of biological evolution than Relativity discarded Newton's Laws of motion, they merely complete them.camanintx
