Andrew Sullivan found a Reuters story describing scientists' discovery of the difference in brain shape between heterosexual sheep and homosexual sheep. Now, whatever implications that may carry for the question of sexuality in the larger sense, I wish not to address. What I do intend to point out is the brazen sci-fi aspect of the following paragraph. For optimal recreation, imagine a tenor voiceover from a 1950's phono recording:
"First the scientists watched the sheep to be sure of their behavior - something that cannot be done with humans. Then they took apart their brains."
