Excerpt: “….highly social insects rely on their distinctive face and body patterns to recognize each other…”
My comment: The difference between RNA-mediated events and evolutionary events attributed to DNA is clear. There is no such thing as an evolutionary event that links cell type differentiation in one species to differentiation in another species via conserved molecular mechanisms in species from microbes to man. Only RNA-mediated events do that.
For example: “In wasps, manipulation of the genetics of evolved species-specific pheromones characterized the change in a pre-existing signaling molecule triggered by a glucose-dependent (Yadav, Joshi, & Gurjar, 1987) stereochemical inversion (Niehuis et al., 2013).”
The nutrient-dependent pheromone-controlled physiology of reproduction links ecological variation via RNA-mediated events to the pheromone-controlled species-specific events that lead to nutrient-dependent reproduction and biodiversity.
Self vs non-self recognition is nutrient-dependent and pheromone-controlled in species from microbes to man by RNA-mediated events.
No evolutionary events have ever been described that could link mutations and natural selection to increasing organismal complexity of morphological and behavioral phenotypes.
That fact, when compared to what is known about RNA-mediated events, is an overlooked aspect of the pseudoscientific nonsense presented in this article on faces.
I can compare their nonsense to examples of how amino acid substitution differentiate the cell types of all individuals of all species via conserved molecular mechanisms, and have done so in a series of published works.
For example, see: Nutrient-dependent/pheromone-controlled adaptive evolution: a model.
Also, ask what it is about facial attraction in homosexuals that can be linked to their sexual preferences.
“This model is attractive in that it solves the “binding problem” of sexual attraction. By that I mean the problem of why all the different features of men or women (visual appearance and feel of face, body, and genitals; voice quality, smell; personality and behavior, etc.) attract people as a more or less coherent package representing one sex, rather than as an arbitrary collage of male and female characteristics. If all these characteristics come to be attractive because they were experienced in association with a male- or female-specific pheromone, then they will naturally go together even in the absence of complex genetically coded instructions.” p-210 Gay, Straight, and the Reason Why: The Science of Sexual Orientation.
