Seeds of life: astrobiological theory and mutations theory

Researchers propose new theory to explain seeds of life in asteroids

October 1st, 2013 in Space & Earth / Space Exploration

Excerpted from above: Both of the established theories – one involving the same radioactive process that heats the interior of Earth, and the other involving the interaction of plasma (super-heated gases that behave somewhat like fluids) and a magnetic field – are still taught to students of astrobiology.

My comment: In the context of astrobiological theory and “seeds of life”…

Does this solve the chirality problem? No, it doesn’t, because the amino acids found in meteorites are mixtures of L- and D-forms. People who support the idea that all twenty amino acids were present from the beginning would have to account for the selection of only one form from the mixture. Since this is highly unlikely, most favor a solution where some form of chemical synthesis preferentially results in a huge excess of left-handed amino acids. So far no example of such a reaction has been found.”

Excerpted from above:  Menzel said the researchers have now definitively refuted the established theory.

My comment:  Chelo et al., refuted the entirety of  mutation-driven evolution (another established theory for which no example has been found). “To our knowledge, this is the first time anyone was able to directly test Haldane’s theory. We have proved it correct for the initial stages, when a new allele appears in a population [i.e., mutations occur]. But our results show that further empirical work and more theoretical models are required to accurately predict the fate of that allele over long time spans [i.e., but mutations are not fixed in the genome].”  Mutations occur but they are not fixed in the genome. Get it? They cannot be involved in natural selection. Can they?

Now we have another refuted theory with an attempt to replace it with another theoretical model that predicts how all of life arose on Earth. But what about the chirality problem? And what about the fact that achiral glycine was an RNA-mediated amino acid substituted in the GnRH molecule and conserved across 400 million years of vertebrate evolution?

Excerpted from above: “The mechanism requires some extreme assumptions about the young solar system,” Menzel said.

My comment: Why not simply make similar extreme assumptions about a young Earth? We can assume that achiral glycine was substituted in the GnRH molecule only 10,000 years ago and that the substitution enabled the ecological, social, neurogenic, and socio-cognitive niche construction that led to the accounting in Biblical Genesis of Creation sans mutations.

The advantage for evolutionary theorists and physicists who prefer assumptions, is that no experimental evidence ever suggested that mutations are fixed in the organized genome of any species. All evidence suggests that conserved molecular mechanisms, such as those involved in the fixation of glycine in the GnRH molecule for either 10,000 or 400 million years, link nutrient uptake to pheromone-controlled reproduction via the creation of de novo olfactory receptor genes. Thus, instead of extreme astrobiological assumptions and theories about mutation-driven evolution, there’s a model of adaptive evolution that includes biological facts.

Okay, I know what you’re thinking. What about the 500 species of stickleback fish that adaptively evolved during the past 15,000 years? Simple, since Earth is only 10,000 years old, the first stickleback fish must have arrived 5000 years earlier via their transport in the watery asteroid that collided with earth and created the watery oceans.  Of course, I’m joking because the astrobiologists must be joking to think evolutionary theorists are going to accept another ridiculous theory of how life began on Earth.  At least I hope they’re joking. How on earth could they not be?



About James V. Kohl 1308 Articles
James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
