I've just posted the following comment on the BioEssays Discussions page for this paper:
The authors should not have dismissed the extensive and well-supported online evaluation of the Wolfe-Simon paper with the single sentence "This paper has generated significant commentary, often as anonymous electronic communications."It hasn't appeared yet - comments have to be first approved by the editors.
Many of the points that Rosen et al. present without attribution were first raised by other researchers in online articles, in authoritative blogs and in signed comments. The subtitle "Arsenic life" is even taken from the discussion's Twitter hashtag "#arseniclife".
* This link just takes you to the Abstract. I can't tell whether the paper is open-access or not - the authors would have to have paid $3000 for this, so probably not. Sorry.
