Pseudogenes: how Darwinian mythology negatively impacts the progress of science

The latest discovery that falsifies Darwinian religion wasn’t without cost. Our search for cures for cancer was negatively impacted by more of their prejudices about pseudogenes.

Uncommon Descent explains the new discovery and why Darwinians opposed it. (H/T ECM)

Excerpt:

Because they are generally noncoding and thus considered nonfunctional and unimportant, pseudogenes have long been neglected. Recent advances have established that the DNA of a pseudogene, the RNA transcribed from a pseudogene, or the protein translated from a pseudogene can have multiple, diverse functions and that these functions can affect not only their parental genes but also unrelated genes. Therefore, pseudogenes have emerged as a previously unappreciated class of sophisticated modulators of gene expression, with a multifaceted involvement in the pathogenesis of human cancer.

And the paper concludes:

The function of the great fraction of the human genome (98%) composed of sequences that do not encode proteins remains a mystery. Pseudogenes are technically part of this fraction, and the examples described here clearly demonstrate that they perform a broad and multifaceted spectrum of activities in human cancer. Therefore, the name pseudogenes, which underlies their close sequence similarity with parental counter-parts, should not imply a negative connotation. They might be “pseudo” genes because they do not encode a protein or because they encode a protein that does not function in the same way as that encoded by their cognate genes. Nonetheless, they are functionally disabled but can perform different functions than their parental gene counterparts.

Here are a few of the more recent errors made by religious Darwinians:

Why do these people believe weird things in the absence of evidence, only to have their speculations falsified when the gaps in our knowledge are closed by scientific progress? Well, evidence doesn’t matter to people who are motivated by naturalistic faith. Like belief in a flat-Earth, the delusion of naturalism is not accountable to scientific evidence. They believe what they want to believe. It’s not up for debate. For some people like Richard Dawkins, a prior lifestyle commitment makes theism (and the moral law!) an impossibility a priori. So there is at the root of atheism a fundamentalist close-mindedness that leads to intellectual dishonesty – not just deceiving others but deceiving themselves. They cannot admit to what reason and evidence is telling them. And it really does affect our progress in many areas, such as cancer research.

The war between atheism (anti-rational hedonism) and science is everywhere, across many scientific disciplines. Science makes discoveries about the Big Bang, the fine-tuning, the origin of life, the usefulness of non-coding DNA, pseudogenes, etc. Instead of accepting what science says and living consistently with science, the naturalist turns to speculations about something coming from nothing, multiverses, aliens, “junk” DNA and other irrational nonsense. The truth of the matter is that atheists will literally believe anything no matter how irrational it is.

New peer-reviewed paper in Nature falsifies Darwinian junk DNA prediction

First, let’s see what Darwinian evolutionists say about junk DNA, before we look at what the experiments show.

Here’s biologist John Timmer to explain the orthodox Darwinian view of DNA from 2007:

Personally, I fall into the “it’s all junk” end of the spectrum. If almost all of these sequences are not conserved by evolution, and we haven’t found a function for any of them yet, it’s hard to see how the “none of it’s junk” view can be maintained. There’s also an absence of support for the intervening view, again because of a lack of evidence for actual utility. The genomes of closely related species have revealed very few genes added from non-coding DNA, and all of the structural RNA we’ve found has very specific sequence requirements. The all-junk view, in contrast, is consistent with current data.

Got that? According to Darwinists, DNA is almost entirely junk – this is what is consistent with the view that creatures have evolved through a process of random mutation and selection. The estimates that I’ve seen from evolutionary biologists range from 95% to 99% junk. Now let’s compare the religion with the lab experiments and separate myth from fact.

Now let’s compare that with intelligent design theorist William Dembski’s view of “junk” DNA, from 1998:

Even if we have a reliable criterion for detecting design, and even if that criterion tells us that biological systems are designed, it seems that determining a biological system to be designed is akin to shrugging our shoulders and saying God did it. The fear is that admitting design as an explanation will stifle scientific inquiry, that scientists will stop investigating difficult problems because they have a sufficient explanation already.

But design is not a science stopper. Indeed, design can foster inquiry where traditional evolutionary approaches obstruct it. Consider the term “junk DNA.” Implicit in this term is the view that because the genome of an organism has been cobbled together through a long, undirected evolutionary process, the genome is a patchwork of which only limited portions are essential to the organism. Thus on an evolutionary view we expect a lot of useless DNA. If, on the other hand, organisms are designed, we expect DNA, as much as possible, to exhibit function. And indeed, the most recent findings suggest that designating DNA as “junk” merely cloaks our current lack of knowledge about function… Design encourages scientists to look for function where evolution discourages it.

Now let’s look at the experimental evidence and see whose prediction was right.

Evolution News reports on a new peer-reviewed paper published in Nature, the top peer-reviewed science journal. (H/T ECM)

Excerpt:

A groundbreaking paper in Nature reports the results of the Encyclopedia of DNA Elements (ENCODE) project, which has detected evidence of function for the “vast majority” of the human genome. Titled “An integrated encyclopedia of DNA elements in the human genome,” the paper finds an “unprecedented number of functional elements,” where “a surprisingly large amount of the human genome” appears functional. Based upon current knowledge, the paper concludes that at least 80% of the human genome is now known to be functional:

The Encyclopedia of DNA Elements (ENCODE) project has systematically mapped regions of transcription, transcription factor association, chromatin structure and histone modification. These data enabled us to assign biochemical functions for 80% of the genome, in particular outside of the well-studied protein-coding regions. Many discovered candidate regulatory elements are physically associated with one another and with expressed genes, providing new insights into the mechanisms of gene regulation.

(The ENCODE Project Consortium, “An integrated encyclopedia of DNA elements in the human genome,” Nature, Vol. 489:57-74 (September 6, 2012) (emphasis added))

If you doubt Evolution News, we can always turn the ultra-leftist Los Angeles Times, reporting on the same study. (H/T Wes from Reason to Stand)

Excerpt:

The $123-million effort involved more than 400 scientists and more than 1,600 experiments during five years of work. If presented graphically, the data generated so far would cover a poster 30 kilometers wide and 16 meters high, Birney has estimated.

This is still just a start — akin to “grainy images beamed back to Earth by the first satellite,” said Dr. Eric Green, director of the National Human Genome Research Institute, which funded ENCODE. But already, it’s throwing up surprises.

Strikingly, the data overturn old ideas that the bulk of DNA in our cells is useless — albeit inoffensive — junk just carried along for the evolutionary ride. Back in 2003 when the human genome was published, scientists estimated that less than 2% of it carries instructions for making proteins, and many of them thought the rest didn’t do very much.

But the new analysis shows that more than 80% of the human genome is active in at least one biological process that the ENCODE team measured. Nearly every part of it could end up being active when the data are more complete.

Here’s the ultra-left-wing New York Times, confirming the statement I made earlier about the dogma of the Darwinians:

The discoveries were published on Wednesday in six papers in the journal Nature and in 24 papers in Genome Research and Genome Biology. In addition, The Journal of Biological Chemistry is publishing six review articles, and Science is publishing yet another article.

[…]The thought before the start of the project, said Thomas Gingeras, an Encode researcher from Cold Spring Harbor Laboratory, was that only 5 to 10 percent of the DNA in a human being was actually being used.

The big surprise was not only that almost all of the DNA is used but also that a large proportion of it is gene switches. Before Encode, said Dr. John Stamatoyannopoulos, a University of Washington scientist who was part of the project, “if you had said half of the genome and probably more has instructions for turning genes on and off, I don’t think people would have believed you.”

It’s just another prediction of Darwinian orthodoxy falsified by experimental evidence published in the top scientific peer-reviewed journal. Will this cause Darwinians to revise their theory to fit the evidence? Not likely. Their motivations for clinging to naturalism, the religion that undergirds Darwinism, are entirely beyond correction by evidence.

I wonder what people like P.Z. Myers and Larry Moran do when their religion comes into conflict with scientific evidence from lab experiments? Do they bitterly cling to their mythology from the 19th century? Or do they adjust their worldview to be in line with the progress of science?

Let Richard Dawkins explain evolution and the role of evidence:

“My argument will be that Darwinism is the only known theory that is in principle capable of explaining certain aspects of life. If I am right it means that, even if there were no actual evidence in favour of the Darwinian theory (there is, of course) we should still be justified in preferring it over all rival theories.” — p. 287, Blind Watchmaker” (1986)

Or Richard Lewontin:

“Our willingness to accept [naturalistic]  scientific claims that are against common sense is the key to an understanding of the real struggle between science and the supernatural. We take the side of science in spite of the patent absurdity of some of its constructs, in spite of its failure to fulfill many of its extravagant promises of health and life, in spite of the tolerance of the scientific community for unsubstantiated just-so stories, because we have a prior commitment, a commitment to materialism. It is not that the methods and institutions of science somehow compel us to accept a material explanation of the phenomenal world but, on the contrary, that we are forced by our own a priori adherence to material causes to create an apparatus of investigation and a set of concepts that produce material explanations, not matter how counterintuitive, no matter how mystifying to the uninitiated. Moreover, that materialism is absolute, for we cannot allow a divine foot in the door.” (Richard Lewontin in New York Review of Books, January 9, 1997, p. 28)

Junk DNA isn’t the only battle in the long war between atheism and scientific evidence. Naturalists fought the Big Bang tooth and nail, trying to save their eternal universe from the progress of science. Naturalists invented the now discredited oscillating model of the universe in order to “explain” the evidence for a cosmic beginning. Naturalists invented the unobservable, untestable multiverse to “explain” the cosmic fine-tuning. Aliens are posited in order to “explain” the origin of life. Precursor fossils are invented without evidence in order to “explain” the Cambrian era explosion in complexity. And so on.

Evidence doesn’t matter to people who are motivated by naturalistic faith. Like belief in a flat-Earth, the delusion of naturalism is not accountable to scientific evidence. They believe what they want to believe. It’s not up for debate. For some people like Richard Dawkins, a prior lifestyle commitment makes theism (and the moral law!) an impossibility a priori. But rational people know that believing something just so that your actions are “justified” doesn’t make what you believe true.

For the intelligent design take on junk DNA, check out this article. To see who was right about predicting whether “vestigial organs” like the appendix have function, check out this post. You can find more predictions that follow from intelligent design right here.

Are Darwinists right to say that the appendix has no useful functions?

Evolution News points to this Washington Post article.

Excerpt:

The appendix “acts as a good safe house for bacteria,” said Duke surgery professor Bill Parker, a study co-author. Its location — just below the normal one-way flow of food and germs in the large intestine in a sort of gut cul-de-sac — helps support the theory, he said. Also, the worm-shaped organ outgrowth acts like a bacteria factory, cultivating the good germs, Parker said. That use is not needed in a modern industrialized society, Parker said. If a person’s gut flora dies, it can usually be repopulated easily with germs they pick up from other people, he said. But before dense populations in modern times and during epidemics of cholera that affected a whole region, it wasn’t as easy to grow back that bacteria and the appendix came in handy.

Evolution News adds:

Additionally, Loren G. Martin, professor of physiology at Oklahoma State University, lists various likely functions for the appendix . Writing on Scientific American‘s website, he includes these examples:

  •  being “involved primarily in immune functions”
  • “function[ing] as a lymphoid organ, assisting with the maturation of B lymphocytes (one variety of white blood cell) and in the production of the class of antibodies known as immunoglobulin A (IgA) antibodies.”
  • helping with “the production of molecules that help to direct the movement of lymphocytes to various other locations in the body”
  • “suppress[ing] potentially destructive humoral (blood- and lymph-borne) antibody responses while promoting local immunity”
  • Additionally, it is “an important ‘back-up’ that can be used in a variety of reconstructive surgical techniques”

Likewise, a few months back David Klinghoffer reported that researchers in the journal Clinical Gastroenterology and Hepatology found:

Individuals without an appendix were four times more likely to have a recurrence of Clostridium difficile, [a pathogen common in hospitals,] exactly as Parker’s hypothesis predicted. Recurrence in individuals with their appendix intact occurred in 11% of cases. Recurrence in individuals without their appendix occurred in 48% of cases.

In other words, the appendix performs important immune-related functions. Thus, the appendix is not there to occasionally explode. With the appendix increasingly considered to be an important organ that you wouldn’t want to lose, researchers have also found that antibiotics can cure many cases of appendicitis (see Eriksson et al., 2006  ).

It just goes to show you that it’s a good idea to not decide your worldview by appealing to cartoons and funny one-liners. First of all, just because something is not perfect, it doesn’t mean that it isn’t designed. The Chevy Volt vehicle that Obama subsidizes with your tax dollars might burst into flames unexpectedly, but it’s still designed. Secondly, no designed object can be perfect in every way – every engineered object is a tradeoff of different, conflicting design goals. It might be nice to have a laptop that can last for 16 hours on a single charge, but then it’s either going to either weigh 12 pounds or cost $4000.

Junk DNA

This isn’t the only time that arguments of “poor design” are made by Darwinists, either – I also hear a lot about Junk DNA.

Look at what the peer-reviewed journal Nature says:

In 1961, French biologists François Jacob and Jacques Monod proposed the idea that ‘regulator’ proteins bind to DNA to control the expression of genes. Five years later, American biochemist Walter Gilbert confirmed this model by discovering the lac repressor protein, which binds to DNA to control lactose metabolism in Escherichia colibacteria1. For the rest of the twentieth century, scientists expanded on the details of the model, but they were confident that they understood the basics. “The crux of regulation,” says the 1997 genetics textbook Genes VI (Oxford Univ. Press), “is that a regulator gene codes for a regulator protein that controls transcription by binding to particular site(s) on DNA.”

Just one decade of post-genome biology has exploded that view. Biology’s new glimpse at a universe of non-coding DNA — what used to be called ‘junk’ DNA — has been fascinating and befuddling. Researchers from an international collaborative project called the Encyclopedia of DNA Elements (ENCODE) showed that in a selected portion of the genome containing just a few per cent of protein-coding sequence, between 74% and 93% of DNA was transcribed into RNA2Much non-coding DNA has a regulatory role; small RNAs of different varieties seem to control gene expression at the level of both DNA and RNA transcripts in ways that are still only beginning to become clear. “Just the sheer existence of these exotic regulators suggests that our understanding about the most basic things — such as how a cell turns on and off — is incredibly naive,” says Joshua Plotkin, a mathematical biologist at the University of Pennsylvania in Philadelphia.

Let’s not be too hasty when making these “bad design” arguments – let’s be guided by the progress of science, and not just by cartoons and snarky terms like “junk DNA”.
