Is any avian species known to be an outlier given the molecular mechanisms of adaptive evolution
The fear of pheromones is denial of reality.
Attempts to discuss the role of nutrient chemicals and pheromones in cognitive neuroscience discussion groups have met with outright hostility. So, let’s wait another week, month, or year until the convergence becomes perfectly clear.
We cannot directly link any individual gene, cell, tissue, organ, or organ system to any behavior without including the rest of the pathway that links gene activation to brain-directed behavior.
The “rules” of the required molecular biology involve ligand-receptor binding. For example, from yeasts to mammals, genetic conservation of the ligand: gonadotropin releasing hormone (GnRH), and the diversification of its receptor (GnRHR) are part of the rules.
Most human sexuality researchers know enough about hormones and behavior to realize that the hormones involved in sexual responses are invariably associated with olfactory/pheromonal input, and never invariably associated with visual input — in any species.
Kudos to anyone else who helps to detail the cross-species comparisons from insects to humans.
Insects serve as a model for human brain function.
