Model vs theory: Progress report!

On June 14, 2013, 1) Nutrient-dependent/pheromone-controlled adaptive evolution: a model and 2) Mutation-Driven Evolution were published with divergent/opposite conclusions. 1) …the largest contributor to the development of our personal preferences may be the unconscious epigenetic effects of food odors and pheromones on hormones that organize and activate behavior. If so, the model represented here is consistent with what is known about the epigenetic effects of ecologically important nutrients and pheromones on the adaptively evolved behavior of species from microbes to…

Can a Quirky Chromosome Create a Second Human Species? Excerpt 1) The first departure from the common house mouse (Mus musculus) was the “tobacco mouse” (Mus poschiavinus), described in 1869 from specimens trapped in a tobacco factory in Valle di Poschiavo, Switzerland.

In a press release accompanying the book, Kohl-who manages a clinical laboratory for a group of physicians at Partell Medical Center in Las Vegas-writes, “My scientific interest in…

Assumptions prove ignorance

Testing Einstein’s Equivalence Principle With Fast Radio Bursts Excerpt: Assuming as a lower limit that the time delays are caused mainly by the gravitational potential of the Milky Way, we prove that fast radio bursts (FRBs) of cosmological origin can be used to constrain the EEP with high accuracy. My comment: Theoretical physicists are allowed to start with assumptions and link them to theories via what they consider to be proof of their assumptions. Unfortunately, the proof of their assumptions…
