Evolution: innovations may have non-adaptive origins (sans mutations)

Q & A: Evolution Makes Do By Chris Palmer Evolutionary biologist Andreas Wagner argues that many evolutionary innovations may have non-adaptive origins. Excerpt: “If exaptations are pervasive, then natural selection—which few doubt is critical for the preservation and spreading of traits—may not be that important for the origin of innovations in life’s history.” See also: Evolution: innovations may have non-adaptive origins (sans mutations)

Human pheromones and autism spectrum disorders (2)

The epigenetic effects are on interactions among all the other neuronal systems and hormone secretion that interact with the GnRH neuronal system, which is central to all developmental differences in the brain of males and females.

Human pheromones and multi-level selection

The problem with multi-level selection in humans seems likely to be one that is due to ignorance about the role of pheromones in the context of ecological, social, neurogenic, and socio-cognitive niche construction.

Human Pheromones and Comparative Epigenomics

What surprises me is that anyone would dispute the significance of modeling behavioral development across the ecological, social, neurogenic, and cognitive niche construction domains by incorporating the epigenetic effects of nutrient chemicals and pheromones on intracellular signaling and stochastic gene expression.
