What effect on the brain motivates us when we see food, or a potential mate?
I acknowledge your evolutionary theory (ies), no matter how ridiculous they seem. I don’t know why you refuse to acknowledge biological facts — unless you simply cannot understand the difference between theories and facts.
From an evolutionary perspective, all measures of visual appeal obfuscate the only real measure of physical appeal across species: olfactory/pheromonal cues of reproductive fitness.
I have elsewhere attempted to partially detail the involvement of DHEA metabolism in the production of species-specific human pheromones, but these details remain speculative.
…using Doty’s logic, how can we say we are visually attracted to the visually appealing physical features of other people when we don’t know what features elicit our response or how they elicit any endocrine or behavioral response?
