IDPs challenges NeoDarwinian membrane pumps in cells


The NeoDarwinism membrane (pump) theory is a modern synthesis of Darwin's theory of evolution by natural selection and the discovery of membrane pumps in cells. It states that the genetic variation that is essential for evolution is caused by mutations in genes that encode for membrane pumps. These mutations can change the way that the pumps work, which can lead to changes in the cell's environment and ultimately to changes in the organism's phenotype.

Mutations in genes that encode for membrane pumps can change the way that the pumps work. For example, a mutation could change the amino acid sequence of the pump, which could alter its structure and function. This could lead to the pump transporting more or less of a particular molecule, or it could even transport a different molecule altogether.


IDP, or Intrinsically Disordered Proteins, break the NeoDarwinism membrane (pump) theory by bypassing the need for proteins to be compartmentalized within a membrane. IDPs are proteins that do not have a fixed three-dimensional structure, and they are able to freely diffuse through the cell. This means that they can interact with other proteins and molecules anywhere in the cell, not just within specific compartments.

The NeoDarwinism membrane (pump) theory states that proteins must be compartmentalized within a membrane in order to function properly. This is because proteins are often specialized to perform specific tasks in specific parts of the cell. For example, proteins that are involved in cell signaling are typically found in the cell membrane, while proteins that are involved in DNA replication are typically found in the nucleus.

IDPs challenge this theory by showing that proteins can function properly without being compartmentalized. IDPs have been shown to be involved in a wide variety of cellular processes, including cell signaling, transcription, and translation. 

The discovery of IDPs has led to a rethinking of the way we understand protein function. It is now clear that proteins are not limited to performing specific tasks in specific parts of the cell. Instead, proteins can interact with other proteins and molecules anywhere in the cell, and they can perform a variety of functions depending on their context.

The discovery of IDPs also has implications for the theory of evolution. IDPs can evolve more rapidly than proteins that are compartmentalized within a membrane. This is because IDPs are not limited by the constraints of the membrane, and they can interact with a wider range of proteins and molecules. As a result, IDPs may play an important role in the evolution of new proteins and new functions outside of NeoDarwinism.

Overall, the discovery of IDPs has challenged the traditional view of protein function and evolution. IDPs are a new class of proteins that are not limited by the constraints of the membrane. This allows them to interact with other proteins and molecules anywhere in the cell, and it gives them the potential to evolve more rapidly than proteins that are compartmentalized.

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
