Constraints on mutational drift

mutations are extremely unlikely and they are also not likely to be adaptive

A mathematical model of phenotypic cause, effects on genes, and affects on behavior

the only thing wrong with mathematical models of cause and effect is that they attribute indirect genetic effects, direct genetic effects, and affects on behavior to something unknown

Non-random adaptive evolution: fast forward to March 2013

Shapiro, JA. Rethinking the (im)possible in evolution (in press) Progress in Biophysics and Molecular Biology.  The author graciously provides an open access preprint of his…

The genetics myth meets the great pheromone myth

I mention this only to note the likelihood that random mutations are not driving the disease processes — like Alzheimer’s and that proper nutrition and pheromone therapy offers hope to an aging population.

Human Pheromones: Epigenetic Effects on Hormones and Their Affects on Behavior

A detailed model exemplifies the effects of olfactory/pheromonal conditioning, which alters genetically predisposed, nutrient chemical-dependent, hormone-driven mammalian behavior and choices for pheromones that control reproduction via their effects on luteinizing hormone.

The neuroscience of sexual attractions

Neuroscientists have known for many years precisely where the boundary lies between genetically predisposed attraction and learned associations in species from microbes to man.

What to do with research results: Warning!

Why didn’t geneticists or evolutionary theorists realize that random mutations do not cause adaptive evolution or that the epigenetic effects of nutrient chemicals and pheromones do cause adaptive evolution?

Human pheromones and the visual appeal of other people (Part Three)

Nutrient chemicals cause ecological niches to form that enable interactions among the conspecifics of social niches. Nutrition and pheromones are both required for epigenetic effects on development of a neurogenic niche in the honeybee brain and a hypothalamic neurogenic niche in the mammalian brain.

Creation vs Evolution? Pre-existing genetic variation, not random mutation

The honeybee is an invertebrate model organism that exemplifies the vertebrate molecular mechanisms of evolution via pre-existing genetic variation, not random mutation, that are detailed here.
