Insects serve as a model for human brain function.
Food odors and social odors influence the same basic neurophysiological mechanism (i.e., the GnRH pulse), which allows them to alter the gene-cell-tissue-organ-organ system pathway which links them to hormones and behavior.
Social selection allows for what most people refer to as natural selection.
I’ve culled these comments from wikipedia as a means to collect some of my thoughts. If ever I can determine how to get permission to edit the wikipedia pages, I will update the information there.
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.
Pheromones are more important to the behavior of species from yeasts to you. Remember this if you plan to celebrate Valentine’s Day.
…he also said that chemical signals between organisms can change genetic expression. This allows the social environment to modify gene expression in individuals and in their offspring.
Copulins are olfactory/pheromonal stimuli from women (human pheromones) that appear to condition increased testosterone and sexual arousal in men.
