The flimsy evidence that environmentally-induced “epigenetic” changes in DNA are transmitted between generations of humans

All of you have read on this site (most recently in my critique of a dire New York Review of Books article) about the buzz concerning “epigenetics”—in particular, about the idea that human DNA can be changed by our exposure to the environment, and the view that such DNA changes can be inherited across several generations.  […]

Another lousy article on epigenetics, this time in the New York Review of Books

I don’t know who the New York Review of Books is getting to vet its biology articles, but this one below (free access) is really confusing. One reason may be that the authors have no particular expertise in evolution. Israel Rosenfeld is an MD with training in neuroscience, while Edward Ziff is a professor at NYU […]

More dumb claims that environmental epigenetics will completely revise our view of evolution

There’s an interesting new paper out on the genetic basis of eye loss in cave fish, reported in a manuscript in biorxiv (not yet peer reviewed) by Aniket Gore et al. (reference and free download at bottom. ) It’s also summarized by New Scientist in the online article below (click on screenshot to go to article), […]

The Daily Beast distorts epigenetics with bogus claims that children can “inherit memories of the Holocaust”

I’ve written extensively on this site about recent claims that environmental modifications of DNA, through either methylation (sticking a -CH3 group onto DNA bases or by changing the histone scaffolding that supports the DNA, can constitute a basis for evolutionary change. This claim is simply wrong. To date, while we can show that environmental “shocks” given […]

Aeon tries to revive Lamarck, calling for a “paradigm” shift in evolution

UPDATE:  As reader Michael found out and reveals in a comment below, Skinner is well funded by Templeton. It crossed my mind, but I thought, “naaaah. . .” and couldn’t be arsed to look it up. But yes, Skinner is eating well from the Templeton trough. It’s pretty clear that Templeton is deeply invested in […]

Another journalist falls for the modern-evolutionary-theory-is-woefully-incomplete scam: says human agriculture is an epigenetic “adaptation”

Yet another journalist seems to have fallen for the epigenetics mavens: those revisionists who think that a form of Lamarckian inheritance can be important in evolution. These people claim that the environment itself directly changes the DNA, not by altering the sequences of bases, but by somehow placing methyl groups on some of the DNA […]

Mukherjee corrects his new book in light of epigenetics kerfuffle, still defends his mischaracterization of gene regulation

You may remember—but not want to remember—the Big Epigenetic Kerfuffle documented on this website (see list of pieces here). It involved Siddhartha Mukherjee, doctor and Pulitzer-Prize-winning author, who was taken to the woodshed by a passel of famous molecular biologists for distorting the state of epigenetics research in a popular article. Mukherjee’s piece, “Same but different,” was […]
