Loss of eyes associated with increased chemosensory abilities leads to a hypothesis of increased tactile sensitivity for food choice and mate choice.
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
Social isolation disrupts myelin production.
Changes in food availability, food type, or the way you get food can trigger evolutionary mechanisms to deal with those changes. The result can be increased brain size and cognition, changes in locomotion and even social changes
The authors are among many, who seem to have missed a likely epigenetic link from maternal and/or acquired ferritin deficiency to thyroxine transport, brain development, and behavior.
A systems biology approach to chronic fatigue that incorporates neuroscientifically established fact is obviously required.
“random” mutations in the genome are not quite so random after all.
The difference between an accurate portrayal of epigenetic effects and those that make claims of adaptively evolved behaviors “(sans epigenetics)” is a difference between fact and story-telling that goes back to the origins of the story more than 120 years ago.
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).
