how much longer it will be until the “bird watchers” realize that the molecular mechanisms of how olfactory/pheromonal input epigenetically effects adaptively evolved behaviors are the same in species from microbes to man, and species of birds are included.
The difference between an accurate portrayal of epigenetic effects and those that make claims of adaptively evolved behaviors “(sans epigenetics)” is a difference between fact and story-telling that goes back to the origins of the story more than 120 years ago.
Olfaction is the ‘sensing agent’ of natural selection, because natural selection requires selection of nutrient chemicals that metabolize to pheromones that control reproduction and species diversification.
“Symptoms” of well-understood brain activity are clearly established via rewards and experience-dependent conditioned preferences that depend on hormonal changes driven by the effects of odors. Food odors and social odors elicit these “symptoms” of activity
Information here, from the human-ethology group, exemplifies confused thoughts about the biological basis of animal behavior.
Those who continue to deny the importance of human pheromones will be among those who are replaced by a new generation that better understands molecular biology and thereby establishes a new scientific truth.
