Our brains "evolve" by epigenetics not Darwin



For 50 years neodarwinists faithfully counted "random mutations" hoping to document the fuel of evolution. With the advent of epigenetics we now know mutations are guided with a purpose. If you read this article your epigenetics will heal your brains "non random" DNA breaks for improved memory. Ouch.

Here is a summary of the article "The Role of DNA Repair and the Epigenetic Markers Left after Repair in Neurologic Functions, Including Memory and Learning":

Epigenetics is the study of how environmental factors can cause changes in gene expression without changing the DNA sequence as with NeoDarwinism. These changes can be long-lasting and can affect a variety of cellular processes, including memory and learning.

Epigenetic guided DNA repair is the process by which cells fix damage to their DNA.

The article discusses how DNA repair can lead to epigenetic changes in the brain. These changes can have positive effects on neurological function. For example, some epigenetic changes can facilitate memory and learning.

The article concludes by suggesting that DNA repair guided by epigenetics plays a critical role in the development and function of the brain.

Here are some additional points that are not mentioned in the article but are relevant to the discussion of epigenetics and neurological function:

  • Epigenetic changes can be inherited from parents to offspring. This means that environmental factors can influence the health of future generations, even if the individual is not directly exposed to those factors.

  • Epigenetic changes can be reversed. This means that it is possible to improve neurological function by changing the environment or by using drugs that target epigenetic pathways. Neo Darwinian changes are irreversible.

The study of epigenetics is a rapidly growing field with the potential to revolutionize our understanding of neurological health. By understanding how epigenetic changes affect the brain, we can develop new treatments for neurological disorders and improve the health of future generations.

Article snippets:

"In eukaryotic cell nuclei, DNA is wrapped around and firmly associated with histone proteins, forming chromatin. When DNA is damaged, the chromatin structure needs to be loosened to allow repair enzymes to gain access to the damage. This requires modifying the histone proteins. These modifications, called epigenetic alterations, do not alter the base-pair sequence. Repair-associated epigenetic alterations are usually transient, removed when no longer needed for repair. However, some remain after repair.

Persistent epigenetic alterations due to DNA repair processes, both histone modifications and methylations of DNA, can also have positive consequences.

Stimulation of brain activity (e.g. learning and memory formation) is often accompanied by the generation of DNA damage in neuronal DNA, followed by repair associated with persistent epigenetic alterations."

Epigenetics explains Neanderthal and Human differences better than Neo-Darwinism

Article :” Unveiling the Epigenetic Landscape of Our Closest Extinct Relatives: A Tale of Neanderthal and Denisovan DNA Methylation,” by Nobel Laureate Svante Pääbo, Science (4/14) The realm of epigenetics, a relatively young branch of genetics, delves into the intricate interplay between genes and their environment, deciphering how factors beyond DNA sequence influence gene expression. DNA methylation, a key epigenetic mechanism, involves the addition of a methyl group to cytosine bases, altering gene activity. By unraveling ancient DNA methylation patterns, scientists have gained unprecedented insights into the epigenetic landscape of our long-lost relatives – the Neanderthals and Denisovans. Harnessing the power of computational methods, researchers have ingeniously reconstructed the DNA methylation maps of Neanderthals and Denisovans, capitalizing on the natural degradation processes of methylated and unmethylated cytosines in ancient DNA. By comparing these methylatio

Many Evolutionists can't "evolve" with Epigenetics

M any evolutionists believe that epigenetics challenges neo-Darwinism. Neo-Darwinism is the prevailing theory of evolution, and it states that evolution is driven by natural selection, which acts on random mutations in the DNA sequence. Epigenetics, on the other hand, is the study of changes in gene expression that are not caused by changes in the DNA sequence itself. Epigenetic changes can be passed down from parents to offspring, and they can be influenced by the environment. This raises a number of challenges for neo-Darwinism. First, it challenges the view that natural selection is the only driving force in evolution. Epigenetic changes can occur without mutations in the DNA sequence, so they can provide a way for organisms to adapt to their environment more quickly than natural selection alone can explain. Second, it challenges the view that evolution is a gradual process. Epigenetic changes can be large and sudden , and they can have a significant impact on an

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

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
