The hormone-miRNA axis, life span, and sexual orientation

Instead of simply offering more evolutionary theory, we detailed the link from the sensory environment to sexual orientation (e.g., the epigenetic effects of pheromones on the gonadotropin releasing hormone neuronal system).

Random mutations theory and pervasive mosaic evolution (the body)

Natural Selection and Sexual Selection must concurrently occur, which makes them non-random processes not driven by random mutations.

Epigenetic effects underlie sexual preferences (duh, and food preferences)

Public release date: 11-Dec-2012 National Institute for Mathematical and Biological Synthesis ) Study finds epigenetics, not genetics, underlies homosexuality Excerpt: “…researchers from the Working Group…

Playing with breasts (e.g, with a new THEORY of why only heterosexual men love them)

It is no fun to be ignored, but that seems to be a common problem for those who challenge theories, whether or not those theories make sense in the context of biological facts.

Transgenerational epigenetic inheritance of sexual orientation

the epigenetic effects of these modifications on sexual orientation and associated behaviors in a unicellular organism were known 16 years ago… why do they now appear to show up only in the behavior of the honeybee model organism?

Human pheromones and IQ via neurogenic and socio-cognitive niche construction

Natural selection “selects” for nutrient chemicals. Sexual selection “selects” for pheromones. There is nothing random about that. “Olfaction and odor receptors provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans.”

Cultural processes are biologically based

Ignoring the molecular biology common to all organisms from microbes to man makes it appear that biological and cultural processes operate somewhat independently across species — as if there were significant differences in the molecular biology of different species.

Human Pheromones in Socioaffective Neuroscience & Psychology

The honeybee is a model organism for understanding the epigenetic link from food odors and social odors to neural networks of the mammalian brain, which ultimately determine human behavior.

The “yuck” factor: aversion to social odors?

Visual input does not directly activate the hypothalamus. Olfactory input (i.e., food odors and social odors) directly activate the hypothalamus. Only via association with odors can what we see influence hormone driven behavior associated with activation of the hypothalamus.

Scents of Adolescence: Are you blind?

A flying mammal that relies on acoustic signaling for food acquisition helps make my case for the importance of olfactory/pheromonal input during the development of sexual preferences.
