Early last week we told you about a new paper published in the Quarterly Review of Biology which suggests that homosexuality arises on account of epigenetic processes rather than ...

So, last week featured a lot of news about a paper that came out in the Quarterly Review of Biology titled “Homsexuality as a Consequence of Epigenetically Canalized Sexual Development.” The authors were Bill Rice (UCSB), Urban Friberg (Uppsala U), and Sergey Gavrilets (U Tennessee). The paper got quite a bit of press. Unfortunately, most of that press was of pretty poor quality, badly misrepresenting the actual contents of the paper. (PDF available here.)

I’m going to walk through the paper’s argument, but if you don’t want to read the whole thing, here’s the tl;dr:

This paper presents a model. It is a theory paper. Any journalist who writes that the paper “shows” that homosexuality is caused by epigenetic inheritance from the opposite sex parent either 1) is invoking a very non-standard usage of the word “shows,” or 2) was too lazy to read the actual paper, and based their report on the press release put out by the National Institute for Mathematical and Biological Synthesis.
