Whale-specific mutations or natural genetic engineering?

24 November 2013 1:00 pm

Excerpt: An international team has decoded the genomes of four minke whales, a fin whale, a bottlenose dolphin, and a finless porpoise, comparing these cetaceans’ genes to the equivalent genes in other mammals.

Journal article abstract excerpt: Our analysis also identified whale-specific mutations in genes…

My comment: Earlier this year, Chelo et al reported that no experimental evidence suggests mutations are fixed in the DNA of organized genomes of any species, and they found no indication of fixed mutations in C. elegans. I’m not sure what experimental evidence for the whale-specific mutations in genes is reported here. Isn’t natural genetic engineering more likely to be responsible for what would be typically be attributed to epigenetic effects of the sensory environment in other species? The report of de novo assembly of the minke whale genome associated with mutations and with amino acid changes seems inconsistent with what occurs in other species.

In other species, the biophysical constraints of thermodynamics and organism-level thermoregulation link nutrient uptake to natural genetic engineering via the amino acid changes reported in the cetacians’  genes. There is no experimental evidence to support mutation-driven evolution in other species. Instead, amino acid substitutions are readily linked to species differences in morphology and behavior via the nutrient-dependent species-specific pheromone-controlled physiology of reproduction. Could it be that the whale-specific mutations are simply associated with the RNA-mediated events and amino acid substitutions but not whale-specific mutations?

Are deer like this one on their way to the de novo assembly of giraffe-specific mutations?


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.
