Epigenetics is the latest DNA buzzword and since current science seems driven by trendiness beware of new “results” incorporating it. Also be suspicious of new results that seem politically correct such as there are no differences between Neanderthals and modern humans, interbreeding, etc. IMO the results reported by younger scientists are more likely to verify their preconceptions rather than be driven by objectivity. This is based on my 35 years as a research geneticist.
I understand your words of caution about current research, but do you believe that epigenetics isn’t legitimate, at least in the sense that it appears that genetic expression depends in some measure on environmental factors?
