My comment:

The evolution of maternal care and paternal care in mammals is dependent on receptor-mediated events that are directly linked from olfactory/pheromonal input to epigenetic effects on intracellular signaling and stochastic gene expression. Transgenerational epigenetic inheritance is one means to ensure that beneficial behavioral traits show up in offspring that mature to provide care for their offspring.

Beneficial behavioral traits enable species survival. Is there a model for how transgenerational epigenetic inheritance enables avian species survival that details the contribution of auditory or visual input — one that does not first require classically conditioned responses to chemical stimuli, for example, like those in food odors?  If not, the early ethologists might have missed something else that’s as important as pheromones are to the theory of biological evolution in species from microbes to man: food.

Is there a model for food acquisition that does not involve olfactory input and classically conditioned behavior (e.g., receptor-mediated hormone-driven behavior)? If so, the same model might be used to link maternal and paternal care to avian species survival. If not, why isn’t there a model for that?

What did the early ethologists think was responsible for nutrient acquisition in surviving avian species? Is there a textbook I can read about that and compare what it says to the Nobel Prize winning works of olfactory researchers like Richard Axel and Linda Buck (2004)? I’m becoming concerned for some of today’s ethologists (and most of the remaining behaviorists). What kind of stories about adaptive evolution have they been taught to believe? Why was there no emphasis on food? It makes me hungry just to think of it. What did they think the birds were thinking about; maternal and paternal care?

About James V. Kohl 1307 Articles
James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
