Epigenetics, Lamarck, and Darwin.

Ryan Gregory at Genomicron educates us about Jean-Baptiste Pierre Antoine de Monet, Chevalier de la Marck and Charles Darwin [Lamarck didn't say it, Darwin did.
What people insist on dubbing "Lamarckian inheritance" in the context of epigenetics is actually closer to the view held by Darwin than by Lamarck....


  1. I just wanted to say that I've really benefitted from reading your blog. I followed you over from a link at onegoodmove a month or so ago, and have been enjoying your posts since then on a regular basis. Keep up the good work.

  2. Greg has found a difference between Lamarck and Darwin in which Darwin i seems closer to the point than Lamarck.

    Still, I find this and other "internalist" manifestations of Lamarck to be interesting.

    It is still debatable to what degree some environmental modifications act simply as "deformations" of the environment, vs. other that are complex, and can be argue to largely be some "built in" response (for instance, growing wings in response to predator kairomones). West Eberhardt discusses this in her book.
