The Myth of Junk DNA


Junk DNA, also known as non-coding DNA, is the DNA that does not code for proteins. It was once thought to be useless, but scientists are now discovering that it plays a number of important roles in the cell. The reason neo darwinists thought it was useless was because only coding DNA is under natural selection. A mutation in the junk DNA can not be selected for by NeoDarwinian definition.

Some of these roles are still not fully understood, but they challenge the traditional neo-Darwinian view of evolution.

Here are 10 ways that junk DNA challenges neo-Darwinism:

  1. Junk DNA is highly conserved. This means that it is very similar across different species, even those that are very distantly related. This is difficult to explain under neo-Darwinism, which predicts that only DNA that is under selection should be conserved.

  2. Junk DNA is transcribed into RNA. This means that it is copied into RNA molecules, which are then used to regulate gene expression. This suggests that junk DNA is more than just useless junk.

  3. Junk DNA contains regulatory elements. These elements control when and where genes are expressed. This suggests that junk DNA plays an important role in development and other cellular processes outside of neodarwinism. 

  4. Junk DNA contains pseudogenes. Pseudogenes are copies of genes that have become non-functional. Neo-Darwinism predicts that pseudogenes should be eliminated by natural selection, but they are found in all genomes.

  5. Junk DNA contains mobile genetic elements. These elements can move around the genome and insert themselves into other genes. This can cause mutations that can be harmful or beneficial. Mobile genetic elements are thought to play a role in NonDarwinian evolution.

  6. Junk DNA contains repetitive sequences. Repetitive sequences make up a large portion of junk DNA. Their function is not fully understood, but they are thought to play a role in genome structure and regulation.

  7. Junk DNA is epigenetically regulated. NonDarwinian  Epigenetic regulation is a way of controlling gene expression without changing the DNA sequence as with neo darwinian mutations and sequence changes. Junk DNA is heavily epigenetically regulated, which suggests that it plays an important role in gene regulation.

  8. Junk DNA is involved in human disease. Mutations in junk DNA can cause a variety of diseases, including cancer and genetic disorders. This suggests that junk DNA is not as useless as once thought.

  9. Junk DNA is involved in NonDarwinian evolution. While junk DNA does not code for proteins, it can still evolve. This suggests that junk DNA is under some kind of NonDarwinian adaptation.

  10. The amount of junk DNA varies widely between species. Some species have very little junk DNA, while others have a lot. This is difficult to explain under neo-Darwinism, which predicts that only DNA that is under selection should be conserved.

These are just a few of the ways that junk DNA challenges neo-Darwinism. As scientists learn more about junk DNA, it is becoming clear that it plays a much more important role in biology than once thought. This new knowledge is forcing scientists to rethink their understanding of neo-Darwinian evolution.

It is important to note that the discovery of the importance of junk DNA is a reminder that there is still much that we do not know about evolution. It is also a reminder that neo-Darwinism is a flawed theory, and that it may need to be modified or replaced to account for new discoveries.

Beyond the Sequence: The Epigenetic "Fingers" That Play the DNA Keyboard

Image
Imagine the keyboard itself is not a standard piano keyboard, but a modular synthesizer, capable of producing an almost infinite array of sounds. The DNA sequence, then, represents the fundamental building blocks of this synthesizer, the raw materials from which all sounds are generated. Epigenetics, our "fingers," manipulates these building blocks, adjusting parameters like volume, timbre, and rhythm, transforming the raw potential of the DNA sequence into a symphony of cellular functions. We can further refine the "fingers" analogy. Consider that each finger represents a distinct epigenetic mechanism: DNA methylation, histone modifications, and non-coding RNA.  DNA methylation, for instance, might be the "index finger," capable of precisely silencing specific genes, like muting individual keys on the synthesizer. Histone modifications, the "middle finger," could represent the ability to adjust the accessibility of the DN...

Rewriting the Rules: Epigenomic Mutation Bias Challenges Randomness in Evolution

Image
This research challenges the long-held dogma that mutations occur randomly, irrespective of their consequences, by demonstrating a clear, epigenome-mediated mutation bias in Arabidopsis thaliana . The study meticulously unveils how mutation rates are not uniform across the genome but are significantly reduced in functionally constrained regions, particularly within gene bodies and essential genes. This discovery fundamentally alters our understanding of evolutionary processes, suggesting that mutation is not a purely directionless force. "Mutation bias reflects natural selection in Arabidopsis thaliana" This opening statement encapsulates the core finding: mutation rates are not random but reflect epigenetic pressures. The authors demonstrate that mutations are less frequent in crucial genomic regions, directly contradicting the prevailing theory of random mutation. This observation suggests an active mechanism that minimizes deleterious mutations in essentia...

Why are Christian philosophers running towards Darwin while biologists are "running" away?

Image
As nature reveals the strength of epigenetics and the weakness of Neo-Darwinism, biologists are “running” away from the long-standing accepted theory. In The Federalist , April 2019, Benjamin Dierker reviews “Why one-third of biologists now question Darwinism”: "Current estimates are that approximately one-third of professional academic biologists who do not believe in intelligent design find Darwin’s Theory inadequate to describe all of the complexity in biology.” Dierker continues, “The important note is that these are not ideologues or religious zealots, nor do they propose a god or biblical solution.  Rather, they find problems in the lack of explanatory power of Darwin’s theory in light of modern understanding of mutation, variation, DNA sequencing and more. These expressions of doubt do not reject naturalism or evolution per se, but the rigor of the Neo-Darwinian model for explaining the development of life.” For 40 years, scientists calculated natural se...
