@Freemor and @idoric@identi.ca thanks for sharing and posting this. I haven't read the article yet but when I saw the note, I couldn't resist sharing this related article from 22 years ago. I think Dr. Fausto-Sterling may be a minor celebrity in Rhode Island.

The article can be found in a format with more legible text, but I like sharing the original as I first encountered it (with images and columns) while browsing a bookstore in 01993. It was really an eye-opener (for me at least) then. What's interesting though is that I just completed a course in developmental biology (of all subjects) from a prestigious private university in Cambridge, MA in 02012 where the professor was dismally clueless about this subject (as shown in homework and exams where male and female were the only two possibilities for correct answers). Your note with linked article makes the professor's cluelessness all that much more vivid.
