Chromosomal rearrangements and hibernation
July 31, 2014 | James Kohl
Hibernation-related proteins are common even in non-hibernating animals, a study shows.

Article excerpt: “These genes clustered on the same chromosome fairly near to one another, leading the researchers to at first believe they were conserved throughout mammalian evolution. But the researchers did not find these genes in the mouse, rat, dog, chicken, and human genomes.”
My comment: In the context of mutation-initiated natural selection and the evolution of biodiversity, do mutations lead to conserved chromosomal rearrangements in some mammals but not in others? I ask because of comments by PZ Myers from his attack on John A. Davison, which prefaced his attack on me.
In my model, the allelic differences between species of mammals and all vertebrates and invertebrates are nutrient-dependent and pheromone-controlled like they are in other species from microbes to man. Ecological variation leads to nutrient-dependent alternative splicings of pre-mRNA and pheromone-controlled amino acid substitutions that differentiate cell types, which are manifested in morphological and behavioral phenotypes.
What experimental evidence of biologically-based cause and effect led to PZ Myers attacks, and why didn’t he tell anyone about the biological basis for his ridiculously pseudoscientific opinion?
How can scientific progress be made if people like PZ Myers do not explain how experimental evidence led to their claims that serious scientists, like Dobzhansky are cranks? “…the so-called alpha chains of hemoglobin have identical sequences of amino acids in man and the chimpanzee, but they differ in a single amino acid (out of 141) in the gorilla.” (1973)
