Mailvox: rhetoric is not science

Michael Z. Williamson takes a page from the true faithful of global warming and Keynesian economics by attempting to defend what is supposed to pass for science with pure rhetoric:

Watching Creationists criticize evolutionary theory is like watching the Brady Bunch criticize the Heller Decision. It would be cute if they didn’t take themselves so seriously, and pose a serious threat to society.

What I find amusing about this is that I was an evolutionary skeptic long before I was a Christian.  And one of the primary reasons I was a skeptic is because as absurd as some of the arguments presented by the creationists struck me, no evolutionist ever demonstrated an ability to address the questions posed to them.  Instead, they always – always – attempted to discuss the Book of Genesis, the age of the Earth, Christianity, the public school system, or some other topic totally unrelated to the one at hand.

That is why I am still a skeptic concerning the secularism’s epic myth, despite having read every book ever published by Richard Dawkins, despite having read Wilson, and Gould, and Shermer, and Hauser, and a number of other well-regarded evolutionary popularizers.  At this point, it might be more accurate to say I am an evolutionary skeptic because I have read those books and been astounded by the obvious logical flaws, evasions, and handwaving that I have encountered in them.

But since Mike is a Standout Author, and therefore capable of exceeding the customary limitations of discussion point-repeating progressives, I assume he is able to rise above the mere rhetoric and actually defend evolutionary theory.  Let’s find out by asking him six simple questions that should be no problem for any man with a solid grasp of the subject.

  1. How do creationists “pose a serious threat to society”?
  2. There are an estimated 1,263,186 animal species and 326,175 plant species in the world.  Assuming the age of the Earth is 4.54 billion years, what is the average rate of speciation?
  3. How many mutations, on average, are required per speciation?
  4. What scientifically significant predictive model relies primarily upon evolution by natural selection?
  5. Which of the various human sub-species is the most evolved; i.e. modified by mutation and natural selection from the most recent common human ancestor? Which is the least evolved?
  6. Is the theory of evolution by natural selection strengthened or weakened by the claim that most DNA is devoid of purpose?

And Stickwick, who happens to be both a Christian and a physicist, beat me to showing how Mike’s attempt to tar all religious people as simplistic binary thinkers was not only demonstrably false, but amusingly inept:

One of the (many) major problems with religion is that its followers insist there has to be a right and wrong answer, and only one of each.

2 + X = (more than 5). Solve for X. One answer only, please.

“There is only one answer: X > 3. Every other possible answer is wrong: it’s not X = 3 and it’s not X < 3.

It’s
absurd to point to our limited understanding of nature and say that
since one person had it partially right and someone else had it
partially right, therefore there is more than one answer. You don’t know
that. And you’ll be hard pressed to build a convincing case, let alone
prove, that there is ultimately more than one right answer to something.
Science doesn’t proceed that way. Also, since when have religious
people insisted there is only one wrong answer?”

Mr. Williamson, with all due respect, you don’t appear to realize that you are not only dealing with a number of people here who are smarter than you are, but are also better educated in science than you are. It may help to keep in mind that at Vox Popoli, those who live by the rhetoric tend to die quickly and brutally by the dialectic.

Here the rhetoric is only used to dance on the grave afterward.

PZ Myers throws out Darwin

As I have predicted for years that they would, biologists are beginning to turn away from Darwin’s dangerous idea of evolution by natural selection.  Even self-styled champions of evolution such as PZ Myers have reached the point of giving up on their erstwhile secular saint:

We aren’t using Darwin’s model anymore; he had no accurate notion of how inheritance worked, for instance — genes and alleles, the stuff of most modern theory, are not present anywhere in his works. “Darwinian” is also problematic. It does have a specific, technical meaning, but it’s often applied thoughtlessly to every process in evolution.

Today Darwin, tomorrow “natural selection”, and, sooner or later, the entire concept of one species coming into existence from another less evolved species through mutation and environmental pressures will be cast into the incinerator of scientific history.  It is merely a matter of time.

Genotribes and superracism

Steve Sailer not only points to one of the fatal flaws of the evolutionary model but manages to lay the foundation for a new form of scientific super-racism:

Thus, there have been, last I checked, a couple of dozen different definitions of species put forward by biologists. Ernst Mayr proposed the simplest: interfertility defines a species. That’s something you can wrap your head around. But there are problems. What about species that reproduce asexually? Among sexually reproducing species, how can you tell whether or not two of the 400 different types of mussels are interfertile or not? As we know from pandas, captive breeding programs are tricky. And what about types of animals who are interfertile but seem worth differentiating, such as dog, wolves, and coyotes?

Indeed, it was while I was thinking about the Endangered Species Act and
the issues surrounding specieshood during the biodiversity debates of
the 1990s kicked off by Edward O. Wilson’s campaign to save the
rainforests that led me to try to ground the study of human biodiversity
in something less woozy than the notion of race as subspecies. Instead,
I reasoned, something we know exists for every human is a
genetic family tree and a biological extended family. If we go back to
thinking about racial groups as extended families, one given a higher
degree of coherence and endurance by partial inbreeding, then we have a
stronger, broader concept that can be used in vastly more human
situations than in just trying to differentiate continental-scale racial
groups by skin color in the post-1492 world.

If I, as a confirmed scientific sub-speciesist, am considered to be a racist on the basis of my acceptance of the current state of biology, then what words can possibly suffice to properly condemn one who would divide humanity on even more substantive grounds than mere genetic science?

But what could we call these extended families with higher degrees of coherence and endurance by partial inbreeding?  One would be tempted to suggest the term “genotribes” were it not for the fact that we are reliably informed that tribalism is the root of all human evil.

Falsification

A scientific gauntlet is hurled:

It started like any other morning, and then we all learned that we would soon be riding cloned dinosaurs to work. All it took was a single benevolent billionaire to pay for the science stuff to get done, and boom — dinosaurs are no longer extinct. Of course, it was a pipe dream from the beginning, but these stories of cloning prehistoric creatures come up from time to time, and most people (reporters especially) don’t want to tell you how impossible it is.

It’s been years since cloned animals first appeared, so why aren’t we able to reach back to the Cretaceous yet? Well, this isn’t just a question of improving our current cloning methods. We lack the fundamental materials to clone anything from 65 million years ago. Taking into account the influence of Hollywood, you could be forgiven for thinking that dinosaur blood is flowing like rivers in labs all over the world. The fact is, we don’t have dino DNA.

In the late ’80s and early ’90s there were a wave of scientists claiming small samples of ancient DNA could be extracted from fossilized bones, eggs, and insects in amber. You probably remember that from a certain dinosaur movie of the era. In the end, all these claims were debunked. It turns out that DNA does not survive that long. The estimated life of a strand of DNA is no more than 1 million years, and even then only if it is in very cold conditions.

If I ever become the insanely wealthy supervillian nature clearly intended me to be, you can be certain that cloning a dinosaur is going to be on my shortlist of things to do.  If nothing else, only to hear the frantic revisionism and witness the attempts to somehow uphold the status quo scientific consensus.  The question is: would the estimated life of a strand of DNA be revised or would the dating methods themselves be called into doubt?

The Ripped Life

An old friend of mine has launched a new business that should be of some interest to the Paleo advocates out there, particularly Supernaut.  It’s called PaleoLife Foods and he describes it as “an ultra-premium, natural nutritional foods company that
was founded on the core, Paleo/Primal Diet-inspired belief that the
foods we put into our bodies should be nothing but the truly
highest-quality, freshest, REAL whole foods as close to nature as
possible — and made up of ingredients that we, as humans, not only
evolved on for millennia but THRIVED on.”

PaleoLife has a new bar out that is available on Amazon and has gotten very good reviews.  I haven’t tried it myself, since my box hasn’t arrived yet, but as my friend is an aesthete of the highest order, I’d be very surprised if it was unpalatable.  If you’re already eating Paleo or are flirting with the idea, you might want to check out their Primal Cocoanut.

Speaking of the Ripped Life, I’ve finally been able to get back onto my 5x/week routine now that the calcio season and the holidays are over.  I’ve learned to take it a little easier, stop when I feel something, and protect my joints a bit, which appears to have helped in avoiding all the niggling little injuries to which I am prone given my distaste for changing my routine.  A minor bicep issue means I still can’t comfortably do pull-ups behind the head, which is frustrating, but the gym has a nice free-weighted rowing machine that, in combination with chin-ups, serves as an adequate substitute for the time being.

My question for Richard Dawkins

Slashdot is inviting interview questions.  Here is mine:  Given that a) a statistically significant minority of students cannot read or write at their grade levels, b) only a very small number of graduating high school students will ever go on to study science in college, and, c) there are already more science majors graduating than there are science-related jobs to employ them, why do you insist it is so important to teach evolution in schools?

Mailvox: an alternative mechanism

Stephen J. takes a logical approach in arguing for evolution by natural selection:

While this question is going to sound snarky, I can only ask our host to
believe it is meant as a genuine inquiry and hope it is answered.

1) Let us take as evidentially established the fact that species which existed in the past now exist no longer and are extinct.

2)
Let us take as evidentially established the fact that not all species
now extant existed at all times throughout the history of organic life;
if nothing else, we know for a fact Homo sapiens did not.

3)
Therefore, it must be possible for species which did not exist to come
into existence by some mechanism, just as species which do exist can go
extinct by any variety of mechanisms.

4) If it is a fact that
new species can come into existence while others go extinct, by what
mechanism other than evolution through natural selection are these
species proposed to arise, and does that proposed mechanism explain more
of the observed evidence than TeNS?

I don’t think it sounds snarky at all.  In fact, this is one of the first rationally competent attempts to defend evolution that I’ve ever seen presented on this blog.  Let’s look at his postulates and his logic and see where it leads us.

1)  I concur.  We know from historical documentary evidence that there are species that previously existed and are now extinct.  We can also infer from fossil evidence that there were a number of other species that previously existed and went extinct prior to the historical record.

2) I tend to agree and am willing to concur here for the sake of argument and on the basis of Occam’s Razor.  We certainly believe that homo sapiens sapiens did not exist from the beginning of the history of organic life on the basis of our current understanding of the geological and fossil records, but we cannot say that with the same degree of confidence that it is a fact in the sense that we say the Dodo is now extinct.  The problem is that there appear to be an increasing number of indications that the current geological and biological timelines are not going to hold up to future evidence, the claimed 521-year half-life of DNA being one of them.

3)  I concur, assuming (2) holds true.

4) Intelligent Genetic Manipulation is the mechanism that I propose.  And yes, I believe that explains more of the observed evidence than TENS, since IGM is a scientific proposition, a readily observed action, and a successful predictive model, whereas TENS is a philosophical proposition, an unobserved process, and an unsuccessful predictive model.

Now, this does not provide any basis for assuming the existence of a Creator God, or even declaring that TENS did not actually take place.  The logical fact of the matter is that even if TENS can be conclusively demonstrated to have taken place in various species, which has not happened despite more than 150 years of trying, that doesn’t necessarily mean the process was sufficient to produce Man.  If one contemplates the biological differences between ape and man, the vast leap in cognitive capacity taking place in a relatively small sum of generational cycles from the proposed common ancestor in comparison with the timelines supposedly required for other, less complicated evolutionary changes, the logic suggests – though it does not prove – that some degree of purposeful genetic manipulation has likely taken place at various points in the origin of the species and the development of homo sapiens sapiens.

I’m not talking about Intelligent Design, but rather intelligent editing.  And the interesting thing is that IGM should be an increasingly falsifiable concept as genetic science continues to improve.  Only recently have we learned that junk DNA serves a purpose; even though we have sequenced various genomes, we haven’t yet understood how the code works or fully comprehended the various ways it can be manipulated.  As our understanding grows, we should be able to develop an ability to recognize patterns that indicate purposeful alterations in the code have been made.

Now, I realize how crazy this probably sounds, especially in light of my argument that Man cannot easily distinguish between God, god, demon, and alien.  But that is where Stephen’s reasonably sound logic takes us. 

Mailvox: education and the evolutionist

MD regurgitates the common mantra of the evolutionary faithful:

You are an educated man and know as well as me that evolution has been verified in countless experiments.  I agree that the precise details of the mechanism are still open to debate.  Since you are essentially making money out of the poor uneducated civilians of your own deeply divided culture, I expect that this E-mail
may not make it to the multitude.  Until then, any
pretensions you have as a serious philosopher – until you spell out your
objections to the actual EVIDENCE of evolution, must be viewed
suspisciously.  Being an intelligent fellow, I know you know this already; hey ho.
First, I note what appears to be a popular use of the adjective “countless”, which in its most common usage apparently means “zero”.  A few days ago, I noted how spin is the hallmark of the weak argument; when someone uses the word “countless” it is often a flashing sign of where a little research will probably prove fruitful.

Second, it is because I have educated myself on the subject over the years that I am aware that there is not a single experiment or study that verifies evolution by natural selection.  Richard Dawkins very nearly admits as much in his homage to the faux science, The Greatest Show on Earth.  Strictly speaking, evolution by natural selection is not even truly scientific, because it is first and foremost a logical argument, which necessarily renders it philosophy rather than science.  At this point, there is less actual scientific evidence for it than for my hypothesis concerning the neural atypicality of atheists.

This isn’t the first time such a claim has been made. Last time, I even asked for any scientific papers that supposedly contained such evidence; after reading the first ten on the list provided, it was readily apparent that none of them contained any such thing and the individual who provided the list of papers had simply done a search for references to “natural selection”. But, for example, showing that guppies become smaller under certain predatory pressures and that this result is “consistent with evolution by natural selection” is very, very, very far from evidence that the guppies have evolved into something other than a guppy.

As I mentioned over one year ago, “I have read seven of Richard Dawkins’s ten books, two of Stephen
Gould’s, a random assortment of books by other authors including Charles
Darwin, Marc Hauser and Daniel Dennett, around 50 published papers
which relate to natural selection in some way, and more than 20 years
worth of magazines such as Natural History and New Scientist.  This doesn’t make me any sort of expert on the subject. But I should think it tends to indicate that I am not completely
uninformed about it. And it’s certainly ironic to be repeatedly
accused of ignorance when not having read any economists from Turgot to
Tobin or theologians from Tertullian to Craig ever seems to prevent
credentialed Cult of Darwin members from opining authoritatively on
economics or theology.” 

How many of the champions of evolution who claim I don’t know what I’m taking about with regards to evolution can claim to have read as much on the subject?  How many have even read On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life? And how many of the biologists who don’t hesitate to spout off on economic matters can claim to have read even half as deeply in the field of economics?

I have repeatedly spelled out my objections to evolution and the actual evidence for it.  First, the evidence doesn’t exist.  Second, the historical timelines that purportedly support it are dynamic.  Third, evolution is a complete failure as a predictive model.  Fourth, it is scientifically and technologically irrelevant; where is the evolutionary engineering.  Fifth, theoretical epicycles are increasingly appearing.  Sixth, it is a repeated failure as an explanatory model.  Seventh, there is a long track record of scientific fraud attached to it.

I have no pretensions of being a serious philosopher.  Quite the contrary, I am merely an intellectual dilettante who takes even his most cherished beliefs with a grain of salt.  But even if I did have such pretensions, my skepticism concerning the Theorum of Evolution by (probably) Natural Selection, Biased Mutation, Genetic Drift, and Gene Flow would not be a strike against me, it would be a mark in my favor. Regardless, I have no problem with my opinions and assertions being viewed suspiciously. If you can find the flaw in the argument, that’s great. Point it out to me, I won’t hesitate to agree and either revise or recant the argument, so long as the flaw is actually there.

That being said, if there is a book on the subject of evolution that an evolutionist feels is missing from my education on the subject, then by all means, I encourage them to send me an epub.  I will read it.  I may even review it.  Of course, there is always the possibility that in doing so, I will point out the obvious errors it contains.

Evolution and a potential rabbit

About five years ago, I publicly predicted that genetic science will eventually rule out the Neo-Darwinian Synthesis and the Theorum of Evolution by Natural Selection.  Now, it would appear that we have a potential mechanism for doing precisely that without needing to discover J.S. Haldane’s hypothetical rabbits in the Precambrian:

Few researchers have given credence to claims that samples of
dinosaur DNA have survived to the present day, but no one knew just how
long it would take for genetic material to fall apart. Now, a study of
fossils found in New Zealand is laying the matter to rest — and putting
paid to hopes of cloning a Tyrannosaurus rex.

After cell death, enzymes start to break down the bonds
between the nucleotides that form the backbone of DNA, and
micro-organisms speed the decay. In the long run, however, reactions
with water are thought to be responsible for most bond degradation.
Groundwater is almost ubiquitous, so DNA in buried bone samples should,
in theory, degrade at a set rate.

By comparing the specimens’ ages and degrees of DNA degradation, the
researchers calculated that DNA has a half-life of 521 years. That means
that after 521 years, half of the bonds between nucleotides in the
backbone of a sample would have broken; after another 521 years half of
the remaining bonds would have gone; and so on.

The team predicts that even in a bone at an ideal
preservation temperature of −5 ºC, effectively every bond would be
destroyed after a maximum of 6.8 million years. The DNA would cease to
be readable much earlier — perhaps after roughly 1.5 million years, when
the remaining strands would be too short to give meaningful
information.

Now, cloning a dinosaur or other ancient species from theoretically nonexistent DNA would not be a directly conclusive debunking of evolution, but would be a sufficiently devastating blow to the evolutionary timelines as to render it every bit as temporally dubious as it appeared when its earliest advocates were worrying about how the time-consuming process could have taken place in only 6,000 years.

I would be interested to hear from those who seriously subscribe to the theory of evolution and learn if, given this announcement of a 521-year DNA half-life, the successful cloning of a dinosaur known to be from a historical epoch well before the 2-million year readability limit would be enough to cause them to abandon their belief in the theory.  And if not, would the discovery of rabbit fossils in the Precambrian be enough to do it?

Mailvox: certainly self-comlimentary

BB affects to be surprised:

I found this site by accident. This discussion of evolution is certainly on a low level for a site that is so deeply self-comlimentary. I am always surprised that people refuse to accept biological evolution because of its supposed implausibility, yet easily accept the idea of spontaneous human appearance. God, in this view, did not need to develop, but just “is.” The plausibility of God goes unquestioned. Said another way, the argument is that man evolved is unsupportable, but the idea that God is and was forever, self-conceiving, is logical.

By the way, I believe in God.

I suggest you apply the same argument to God and man. But I readily admit that doing so will not answer the Question that you and I both have. The old question of something out of nothing.

Color me dubious.  An affectation of disinterest, followed by a nonsensical naked assertion, followed by a complete strawman.  And notice how quickly the “defense” of evolution rapidly transitions to its scientific plausibility to a philosophical attack on God.  What I find amusing is how the Neo-Darwinian faithful continue to insist that evolution is every bit as probable no matter how much the necessary complexity is observed to have increased. 

The recent recognition – long expected by me and others – that genetics are much more complex than previously understood and that junk DNA is somehow involved in the process, to say nothing of the toppling of the “tree of life”, all significantly increase the improbability and necessary time scales of evolution by natural selection.  And yet, there hasn’t even been any attempt to account for these additional complexities, partly because evolutionary biologists are both relatively innumerate and logically challenged, but mostly because the so-called science is little more than an article of willfully blind faith.
