Abstract

Koonin, in an article in this issue, claims that CRISPR–Cas systems are mechanisms for the inheritance of acquired adaptive characteristics, and that the operation of such systems comprises a “Lamarckian mode of evolution.” We argue that viewing the CRISPR–Cas mechanism as facilitating a form of “directed mutation” more accurately represents how the system behaves and the history of neoDarwinian thinking, and is to be preferred.
