The Naturalistic Origin Of Life (RNA World Critiqued)

The Origin of Life, two world views, Darwinian evolution theory vs Biblical Creation.

The RNA World Hypothesis is presented in the first half of this video from Dr. Pierre Durand, University of the Witwatersrand, Johannesburg. PhD student Nisha Dhar Quote (Via TImes Live):

  • ‘RNA molecules were the first molecules which could have given rise to life.’
  • ‘This event is believed to have taken place possibly 4 billion years ago, at a time when a young earth was a hostile place with a volcanic activity and an atmosphere that had yet to contain oxygen. RNA, said Durand, was hardy and would have survived these kinds of conditions.’

….Evolutionists would have us to believe that non-living elements and molecules joined together and developed increasing biological capabilities. Those who believe in intelligent design reject this hypothesis, insisting that neither RNA nor living cells are able to evolve spontaneously. While some disagreement exists among those in the evolutionary community on the time frame for such alleged reactions to occur, the consensus is that, given large amounts of time, single-celled bacteria were formed. But all known biological principles militate against this notion. Even billions of years could not provide mechanisms for the reaction products to evolve advantageous characteristics and form DNA and cell proteins, let alone create strings of RNA nucleotides, arriving at just the right sequence in order to code for a functional protein. The four nucleotide bases that form RNA (adenine, guanine, cytosine, and uracil) can be arranged in an exponential array of combinations and lengths. For an actual, functional protein to be coded, a precise sequence of nucleotides must be obtained. Forming the code for even one protein by evolutionary means is impossible, without even considering the necessity of the number that work together in a single cell.

There is no scientific evidence to suggest that RNA is spontaneously being created and capable of forming pre-cellular life today. While some artificial ribozymes have been created in the laboratory (reviewed in Chen, et al., 2007), there are still significant holes in reproducing an RNA world to support the hypothesis. The ribozymes created artificially lack the abilities to sufficiently process themselves, and there is no evidence of them producing large quantities of advantageous nucleotide sequences. Moreover, no system has ever created cellular life. There is even significant debate among scientists over the conditions and constituents of a “prebiotic Earth” model.

The RNA World Hypothesis is simply another attempt by scientists to explain the origin of life to the exclusion of the divine Creator. Given the absolute impossibility of life originating from the reactions of non-living matter, it can be justified that RNA did not predate other biological molecules. All biological molecules were created together to work in concert. RNA was designed to be the essential intermediate between DNA and proteins, making our cells capable of sustaining life as it was created. The designer of this system must be the intelligent Designer, the God of the Bible.


Environment Can Influence Genetic Expression

See also Dr. Noble’s information on this newer understanding that adds layers of difficulty to the classic story of evolution (see also my post on quantum biology that is adding to the complexity of this issue). The following is from PHYS-ORG:

…New research from the University of Maryland provides a surprising possible explanation. For the first time, developmental biologists have observed molecules of double-stranded RNA (dsRNA)—a close cousin of DNA that can silence genes within cells—being passed directly from parent to offspring in the Caenorhabditis elegans. Importantly, the gene silencing effect created by dsRNA molecules in parents also persisted in their offspring.


“This is the first time we’ve seen a dsRNA molecule passing from one generation to the next,” said Antony Jose, an assistant professor in the UMD Department of Cell Biology and Molecular Genetics and senior author on the study. “The assumption has been that dsRNA changes the parent’s genetic material and this altered genetic material is transmitted to the next generation. But our observations suggest that RNA is cutting out the middle man.”

Jose and his team, including graduate student and lead author Julia Marré and former research technician Edward Traver, introduced dsRNA marked with a fluorescent label into the circulatory system of C. elegans worms. They then watched as these fluorescent RNA molecules physically moved from the parent’s circulatory system into an egg cell waiting to be fertilized.

In a surprising turn of events, some of the dsRNA molecules could not silence genes in the parent because the dsRNA sequence did not match any of the parent’s genes. But the dsRNA molecules did silence genes in the offspring, when the new worm gained a copy of the matching gene from its other parent. This suggests that, in some cases, gene silencing by dsRNA might be able to skip an entire generation.

“It’s shocking that we can see dsRNA cross generational boundaries. Our results provide a concrete mechanism for how the environment in one generation could affect the next generation,” Jose said. “But it’s doubly surprising to see that a parent can transmit the information to silence a gene it doesn’t have.”….
