Did parental love evolve separately in birds and mammals?


Excerpt: Romantic (erotic) love, an important component of human reproductive and sexual behavior, has its origins in parenting behavior. In reptiles, there is neither parental care nor an affectionate or affiliative bond between the two parents. Parental care evolved separately in birds and mammals and, as first pointed out by Eibl-Eibelsfeldt, “with parental care love came into the world ”

My comment: Claims that behavioral traits somehow concurrently evolved with morphological traits are consistently made without any biologically-based experimental evidence to support them. Serious scientists have refuted those claims with experimental evidence that shows how nutrient-dependent RNA-directed DNA methylation links amino acid substitutions and chromosomal rearrangements from ecological variation to ecological adaptations in species from microbes to man.

For example, Horton et al., (2014) linked differences in parental feeding to different morphological and behavioral traits in white-throated sparrows.The physiology of reproduction is controlled by the metabolism of nutrients to species-specific pheromones in birds, which links differences in their morphological and behavioral phenotypes to mammals via conserved molecular mechanisms detailed in Nutrient-dependent/pheromone-controlled adaptive evolution: a model.

From the same educational source: “Sex Archive Info,” see also: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences. Human ethologists, evolutionary theorists, and most social scientists seem to believe that heterosexual love evolved separately in birds and mammals, which suggests that mutations and/or parental love is the cause of homosexual preferences. I found that pseudoscientific nonsense even more difficult to believe than any of the other pseudoscientific nonsense that theorists have touted for decades.

Therefore, I first published an award-winning review (with human ethologist co-authors) that linked hormone-organized and hormone-activated behaviors in all vertebrates and invertebrates. See: Human pheromones: integrating neuroendocrinology and ethology.

My co-authors did not want to address any issues of sexual orientation in a follow-up with me, so I published the award-winning monograph The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences as a journal article concurrently published as a book chapter in the Handbook of the Evolution of Human Sexuality.

Meanwhile, the claims of human ethologists and evolutionary theorists have continued to become more ridiculous as scientific progress is made by serious scientists more than 50 years after Dobzhansky (1964) described the difference between theorists and serious scientists.  “…the only worthwhile biology is molecular biology. All else is “bird watching” or “butterfly collecting.” Bird watching and butterfly collecting are occupations manifestly unworthy of serious scientists!”

Some things do not change. Bird watchers (e.g., human ethologists) make the same claims about evolved behaviors that they have always made. Their claims continue to be based on observations instead of evidence that links conserved molecular mechanisms of biologically-based cause and effect in species from microbes to man via their nutrient-dependent pheromone-controlled behaviors.

About James V. Kohl 1308 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.
