“Junk” DNA – The Biggest Blunder of Evolutionary-Based Science
Geneticists once believed that DNA sequences (genes) were the key to building and maintaining healthy
cells. When all sorts of peripheral genetic elements were discovered, evolutionary geneticists referred to
them as “junk DNA” on the assumption that they were nothing but useless remnants left over from
evolutionary predecessors. Come to find out, these regulatory elements are the key to cellular health and
development, as well as the primary link to disease when not operating properly.
For over 50 years, evolutionary-based researchers have arrogantly denied the critical nature of “junk
DNA,”which has been discoverely to consist of over 98.5% of DNA. The study of how these regulatory
elements can change a gene's function without altering its DNA sequence is called “Epigenetics”and it's now
the most funded area in genetic research:
- “All the cells in the body have the same DNA sequence (genome), but it is how this DNA sequence is
interpreted that results in the formation of different cell types. Epigenetic changes control how a DNA
sequence is interpreted, specifically how different genes are switched on and off in different cell types,
tissues and organs.” …
'This suggests that DNA modifications are more dynamic than we previously thought.”
Cambridge Unversity and Babraham Institute, “Cambridge technique to transform epigenetics,” April 20,
2012, Business Weekly.
- “DNA is normally packed tightly into the nucleus of a cell and housed into chromosomes. Within
chromosomes lie many chemical perturbations that modify how genes are expressed, without anything to do
with the underlying DNA sequence, explained Aline Cerf, a postdoctoral associate who led the study.
Studying these chemical modifications is a relatively new field called epigenetics.”

Upon resigning as Director, Francis Collins regretfully stated that the National Human Genome Research Institute's gene-centered approach was misguided and had been “dismissive” of regulatory elements, i.e. “junk DNA”:
- “A slew of recent but unrelated studies of everything from human disease to the workings of yeast suggest that mysterious swaths of molecules - long dismissed as 'junk DNA' - may be more important to health and evolution than genes themselves …
'It's a radical concept, one that a lot of scientists aren't very happy with,' said Francis S. Collins, director of the National Human Genome Research Institute. 'But the scientific community is going to have to rethink what genes are, what they do and don't do, and how the genome's functional elements have evolved.'”

- "Ah - so much of the genome - after all only about 1.5% of it is coding for protein. The rest of it is probably involved in this regulatory stuff, and for a long time were were a bit dismissive about that 98.5% of it and said that a lot of it was kind of a junk. I don't think people are using the word "Junk" any more when they are talking about the genome, because the more we study, the more functions we find in that "filler" - which is not a "filler" at all."

In 1956, many scientists, including Nobel laureate Barbara McClintock, proposed that “junk DNA” was essential and functional genetic material. But, since that view didn’t fit with the presupposition of evolutionary philosophy, their proposals were dismissed and the next 50-60 years of research was primarily focused on pursuing the dogma that genes controlled everything:
- “Bejerano and his colleagues aren't the first to suggest that transposons play a role in regulating nearby genes. In fact, Nobel laureate Barbara McClintock, PhD, who first discovered transposons, proposed in 1956 that they could help determine the timing for when nearby genes turn on and off."

This ignorance has proven to be evolutionary-based science's biggest blunders is still the most insidious
obstacle standing in the way of medical discovery and progress, even though it “became apparent in 2001,
when the human genome sequence was first published.”:
- “Gene regulation has turned out to be a surprisingly complex process governed by various types of regulatory DNA, which may lie deep in the wilderness of so-called junk DNA that lies between genes. Far from being humble messengers, RNAs of all shapes and sizes are actually powerful players in how genomes operate. Finally, there's been increasing recognition of the widespread role of chemical alterations called epigenetic factors that can influence the genome across generations without changing the DNA sequence itself. The scope of this 'dark genome' became apparent in 2001, when the human genome sequence was first published.”

- “For me, the most important outcome of the human genome project has been to expose the fallacy that most genetic information is expressed as proteins … In contrast to protein-coding genes, the extent of noncoding intronic and intergenic sequences increases markedly with complexity; only 1.5% of the human genome encodes proteins ...
These observations suggest that we need to reassess the underlying genetic orthodoxy, which is deeply ingrained and has been given superficial reprieve by uncritically accepted assumptions about the nature and power of combinatorial control.”

“For many reasons, the simplistic view that everything in biology is determined by DNA sequence has
dominated biology, medical research, and the study of evolution for over half an century. But this has
inhibited the development of many innovative ideas in biology, prohibited a holistic and comprehensive view
of life and the mechanism of evolution, and delayed medical research on cancer and many other diseases for
a few decades.”

Unwilling to deny the ridiculous assumption that “junk DNA” is just a bunch of useless genetic
remnants that are left-over from evolutionary predecessors, many zealous evolutionists are still
preaching their nonsense:

say 'Darwin was wrong' (New Scientist under Roger Highfield is a lamentable example). I am heartily sick of
the ‘epigenetics’ bandwagon and almost look forward to the next one, whatever it turns out to be."

Because evolutionary-based presuppositions are the foundation of almost ALL research dollars, we are now paying for this horrific blunder. Since it has been discovered that most diseases, especially cancer, are caused by alterations with “junk DNA” instead of the protein-coding genes themselves, imagine the medical treatment and cures we could be experiencing today if evolutionists would only have kept an open mind. Slow to come around, there is hope and some evolutionary-based geneticists are finally changing their minds about “junk DNA”:
- “Once considered unimportant 'junk DNA,' scientists have learned that non-coding RNA (ncRNA) — RNA
molecules that do not translate into proteins — play a crucial role in cellular function. Mutations in ncRNA are
associated with a number of conditions, such as cancer, autism, and Alzheimer's disease.”

- “MicroRNAs are non-coding genes that often reside within ‘junk DNA’ and regulate the levels and functions
of multiple target proteins — responsible for controlling cellular processes in the brain ...
James Uney, Professor of Molecular Neuroscience in the University’s School of Clinical Sciences, said: 'These
findings are important as they show that very small changes in microRNA genes will have a dramatic effect
on brain function and may influence our memory function or likelihood of developing neurodegenerative
diseases. These findings also suggest that many more human mirror microRNAs will be found and that they
could ultimately be used as treatments for human neurodegenerative diseases such as dementia.'”

- “In fact, it looks so useless that, until recently, many scientists considered it to be just a leftover artifact of eons of evolution.Recently, however, research has shown that defects in the development or function of primary cilia are associated with many human disorders, including polycystic kidney disease, skeletal malformations, neural tube defects, as well as obesity. Clearly there's more here than meets the eye. Scientists have since decided that the primary cilium works as a kind of antenna to help the cell respond to outside chemical signals and mechanical forces.”

- “Gerstein and postdoctoral associate Nitin Bhardwaj analyzed regulatory networks of five diverse species, from E. coli to human, and rearranged those systems into hierarchies with a number of broad levels, including 'master regulators,' 'middle managers' and 'workhorses.' In most organisms, master regulators control the activity of middle managers, which in turn govern suites of workhorse genes that carry out instructions for making proteins.”

- “When the human genome was fully sequenced in 2004, approximately 20,000 genes were found. However, it was discovered that living cells use those genes to generate a much richer and more dynamic source of instructions, consisting of hundreds of thousands of genetic messages that direct most cellular activities. Frey, who has appointments in Engineering and Medicine, likens this discovery to 'hearing a full orchestra playing behind a locked door, and then when you pry the door open, you discover only three or four musicians generating all that music.'
To figure out how living cells generate vast diversity in their genetic information, Frey and postdoctoral fellow Yoseph Barash developed a new computer-assisted biological analysis method that finds 'codewords' hidden within the genome that constitute what is referred to as a 'splicing code'. This code contains the biological rules that are used to govern how separate parts of a genetic message copied from a gene can be spliced together in different ways to produce different genetic messages (messenger RNAs). 'For example, three neurexin genes can generate over 3,000 genetic messages that help control the wiring of the brain,' says Frey.”

- “Pseudogenes are relics of former genes that no longer possess biological functions. They are abundant in the genomes of complex organisms such as vertebrates and flowering plants and provide a useful resource for studying mutation rates and neutral evolutionary patterns. Processed pseudogenes can be regarded as fossilised footprints of past gene expression, permitting a peek into ancient transcriptomes … Recent studies found some pseudogenes to possess apparent functions in gene regulation, creating a difficulty in defining pseudogenes.”

- “An entire class of seemingly useless genetic components may actually regulate gene activity, suggests a study that — though preliminary — has potentially transformative implications for biology.
The findings involve apparently redundant copies of genes, called 'pseudogenes,' and RNA molecules that would normally carry out genetic instructions, but appear to be disabled.
'This is a completely new way by which genes can be regulated. It’s something that up to this point has been undiscovered,' said Leonardo Salmena, a Harvard Medical School geneticist and co-author of the study, published June 23 in Nature.'”
