@sapinker But we certainly know that transposons can be heritably silenced, as can paramutable alleles. Baby, bathwater, etc...

.
@DamonLisch@sapinker ...and how many generations do they last in outside the lab? Do they cause DNA sequence alterations and how often? -
@EmilKarlsson@sapinker Most transposons are epigenetically silenced most of the time in lab or field. No DNA sequence changes. -
.
@DamonLisch@sapinker if there are no DNA sequence changes, it is unlikely to be an as powerful factor in evolution. -
@EmilKarlsson@sapinker point is that nature doesn't care about ideology. We don't know what we don't know -
@DamonLisch@sapinker then perhaps proponents of Epigenetic Lamarckism shouldn't be making such claims. -
@EmilKarlsson@sapinker Epigenetics in plants may have no effect on evolution. But it's an idea worth thinking about. -
.
@DamonLisch@sapinker sure, but if proponents want to be taken seriously, they need to present evidence. - 5 more replies

@sapinker not a very clever demolition of "epigenetics = lamarckism". lamarckism requires more than acquired characters' heritabilityThanks. Twitter will use this to make your timeline better. UndoUndo

@sapinker The article is being defended by author though.Thanks. Twitter will use this to make your timeline better. UndoUndo

@sapinker And certainly not a threat to traditional models of evolution. The rebuttal's title is overly dramatic. PTM is "in addition to."Thanks. Twitter will use this to make your timeline better. UndoUndo

@sapinker ..."neo-Lamarckian" events is correct and rising. That said, it is not a threat to traditional models of transcription/transltn.Thanks. Twitter will use this to make your timeline better. UndoUndo

@sapinker ...on the truth that PTM has allowed for Lamarckism in a way Lamarck never would have conceived. The evidence for these...Thanks. Twitter will use this to make your timeline better. UndoUndo

@sapinker While the New Yorker piece overstated (as critics note) the role of post-translational modification, I was glad to see reporting..Thanks. Twitter will use this to make your timeline better. UndoUndo
