Lamarckian or not, CRISPR-Cas is an elaborate engine of directed evolution

  • Eugene V. KooninEmail author
Article

I appreciate the interest of many biologists and philosophers of biology in my discussion of the conceptual and philosophical aspects of CRISPR-Cas (Koonin 2018) and their insightful comments. Perhaps, not surprisingly, the primary topic that is addressed in 4 of the 6 commentaries is my proposition that the evolutionary changes mediated by the CRISPR-Cas systems are of the Lamarckian character. It is interesting that two of these commentaries (Wideman et al. 2018; Woolley et al. 2018) object (strenuously, in the latter case) to the characterization of the CRISPR-Cas systems as engines of Lamarckian evolution, whereas the other two (Jablonka 2018; Veigl 2018) largely concur with my view and extend it. Perhaps, this also should have been anticipated because Lamarckian evolution is a perpetually controversial subject, and as aptly noticed by Jablonka, many biologists have a “knee-jerk” reaction to the very name “Lamarck”. In this brief response, I first address the two “anti-Lamarckian”...
