I couldn’t resist. Shakespeare’s Sister has a satirical post on the female reproductive tract as a source of gay rays, and evolgen chimes in, noting the similarity of her diagram to the nematode vulva (it’s true—if mammalian vulvas are radiating gayness, nematodes are even more common; Ben Shapiro is probably crawling with hermaphroditic nematodes, all oozing sexual ambiguity all over him). So I had to repost my summary of the evolution of the mammalian vagina, and I want you to look at the diagram of Hox gene expression in the female reproductive tract. It’s like a rainbow! Admittedly, there are no disco balls, pink triangles, or floating Melissa Etheridge CDs, but this is research that has only just begun—as we get more details, we’ll have to sprinkle more symbols in there, and I think Shake’s ideas are excellent suggestions.
Once again, liberal leftist irony stands at the forefront of modern scientific research.
(Oh, and if any guys are feeling left out, I do have an article on penis evolution. All the pictures are in black and white, without any hint of a rainbow.)
