Holding Back Scienceit:
For some evolutionary biologists, just hearing the term epigenetics raises hackles. They balk at suggestions that something other than changes in DNA sequences—such as the chemical addition of methyl groups to DNA or other so-called epigenetic modifications— has a role in evolution.
Or as one researcher explained:
People are really stubborn about accepting that that’s possible.
Aside from violating evolution’s ground rules against heritable directed change, otherwise known as the inheritance of acquired characteristics, epigenetics takes the unlikeliness of evolution to an entirely new level.
We would have to believe that evolution’s undirected, random change somehow created an astonishingly complex adaptation machine. Not only do the sheer intricacies and interdependencies of epigenetics, and the lack of an evolutionary fitness pathway rule out a random origin, but the violation of Occam’s Razor is colossal. We must believe that evolution created a profoundly complex machine which facilitates an entirely new form of evolution.
Religion drives science, and it matters.
