Excerpt: “There’s a reason these crows make tools and other birds don’t,” he says. “It’s not a miracle.”
THAT SENTENCE, along with the even shorter phrase “no miracles,” is a favorite of Gray’s.
The power of evolution “to explain many things,” as he puts it, struck him when he was still in high school in Tauranga, south of Auckland, after reading Richard Dawkins’s The Selfish Gene.”
Excerpt: Although controversial, his papers have so stirred the field that several researchers credit him with being in the vanguard of a revolution. Gray’s fresh approach prompted Germany’s Max Planck Society to tap him as co-director of its new Institute for History and the Sciences in Jena. Gray’s other research focus, animal cognition, was also thought to be beyond the ken of science. But this black box, too, yields to evolutionary thinking, Gray insists.
My comment: “Evolutionists Cannot Account for the Origin of the Sense of Smell” in the book “The Miracles Of Smell And Taste” challenges the representations made by Russell Gray.
An Islamic Creationist author cites works by “John T. Caprio of Louisiana State University [who]states that initially, the sense of smell developed in order to identify amino acid-like chemical substances soluble in water. The ability to determine molecules floating in the air is an adaptation of that original mechanism.96”
In my model, ecological variation leads to ecological adaptations via a direct link from the epigenetic landscape to the physical landscape of DNA in the organized genomes of species from microbes to man. It seems miraculous to me that 1)the experience-dependent de novo Creation of cell surface receptors allows the entry of nutrients into cells. 2) The receptors link nutrient uptake and the pheromone-controlled physiology of nutrient-dependent reproduction. 3) Thermodynamic cycles of protein biosynthesis and degradation link nutrient uptake and the metabolism of nutrients to fixation of amino acid substitutions via RNA-mediated events. 4) The RNA-mediated events replace the need for any evolutionary events to be associated with DNA because 5) the RNA-mediated events epigenetically link ecological variation and ecological adaptations in all cells of all individuals of all genera.
It would seem like a miracle to me if anyone used evolutionary ideas to establish a similar biologically-based biophysically-constrained link to the nutrient-dependent morphological and behavioral diversity that appears to result from a single amino acid substitution in cell types and the detection of cell type differentiation via what is commonly referred to as the sense of smell.
If Dobzhansky was not still dead, an evolutionary event that linked detection of amino acid substitutions to cell type differentiation in primates would probably seem like a miracle to him, too. See, Dobzhansky, 1973 “…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.”
