> the clitoris did not even make it into standard anatomy textbooks until the 38th edition of Gray’s Anatomy was published in 1995.
This seemed surprising, as it hews too close to an annoying meme in feminism and history generally, that people in prior eras were idiots. And it turns out to be wrong. The clitoris was in Gray's Anatomy until 1947, when it was removed by the editor Charles Goss for the 25th edition. See https://projects.huffingtonpost.com/projects/cliteracy/embed... Indeed, the clitoris had been depicted in Classical medical books.
Why it was removed--and stayed removed for nearly 50 years--would make for an interesting story about mid-century culture, if not for a cynical throwaway comment, though it seems nobody knows Goss' actual motivations.
There's a fair amount of modern/modernist-era thinking about bending the chaos of humanity to meet rigid ideal social structures, from about the late nineteenth to late twentieth century. And to be clear, the chaos of the early industrial period led to marked declines in public health, sanitation and the like. Some of these innovations worked reasonably well (the standardization of healthcare and schooling), some of them had unforeseen side effects (replacing horses and their large amounts of fecal matter with cars and invisible pollution), and some straight up did not work (much of the social engineering that went into low-income public housing in the West)
I don’t know about “idiots” but bias towards women was obviously real and prevalent. Treating the idea that that might have influenced medical literature as a “meme” is slightly bizarre to me.
The meme is that before [insert your contemporary period] people were so backwards that they would miss something like the clitoris entirely. The meme isn't that people and cultures were prejudiced or biased, but that they were prejudiced in an idiotic way. If you believe that's how prejudice works, then you'll be utterly blind to much contemporary prejudice.
EDIT: Relatedly, The Guardian article sites the statistics about female genital mutilation. And you might think, how could people in this day be so cruel? Well, in some (but not all) of those cultures, such as parts of West Africa, female sexual pleasure is highly valued, a clitoral circumcision involves removing the clitoral hood only, similar to circumcision for men, and is viewed as enhancing female sexual pleasure, specifically for oral sex, an act that lacks any negative connotations. Now, embedded in that narrative might be a deeper, more subtle bias against women, but by not appreciating and grappling with that dynamic you're ignoring and diminishing how many women in those cultures understand feminism, which is its own anti-feminine and culturally centric (i.e. "colonial") bias.
Isn't type 1a circumcision (removal of the clitoral hood, but not other parts) very rare? At least that's what the Wikipedia article claims, referencing a 2008 WHO report.
Page 7 [0] of the report seems to indicate that FGM reconstruction actually seems to have negative outcomes post-surgery. I'm surprised by this. I'm also shocked to see how prolific FGM is too (230 million women?!).
No, it's important context, and attempting to suppress it does everyone a disservice. Without taking these kinds of points of comparison into consideration, one becomes susceptible to https://en.wikipedia.org/wiki/Base_rate_fallacy , and may become convinced about supposed bias where the evidence doesn't support the claim, contradicts it or even shows the opposite.
Another classic example is the discourse around "missing and murdered Indigenous women" in Canadian politics. It was popular enough around a decade ago to be more or less a set phrase. To listen to politicians and wonks discussing the matter, you would imagine that Indigenous men didn't ever get kidnapped or murdered. As a matter of fact, the statistics showed that it happened to them at over twice the rate of the women. (They also showed that it was not an alarmingly high rate compared to other Canadian populations, and that the perpetrators were usually themselves Indigenous — as you'd expect for generally fairly isolated communities.) But you would get silenced in many places (e.g., banned from the Canada subreddit) for pointing to those statistics.
Respectfully, there is no point in directly or indirectly trying to defend something that is objectively 100% wrong on any level. Every single human being with a brain on this earth can derive that it is wrong from first principles. There is no point trying to save a cultural practice that is wrong, stupid, and therefore evil, just because some people thousands of years ago thought it was good. You yourself can clearly see it is wrong on its face. And if you tried to object to that, you would be lying.
Dumb question, why do “sensitive” spots on the body need more nerves? Couldn’t you just have the normal touch-sensing nerves and map signals from specific spots on the body to stronger/pleasurable qualia in the brain?
Not a dumb question. The shortest (and at a glance unsatisfactory) answer is because it works, and therefore it evolved that way.
Going in detail, first consider that for a feature to be evolutionarily selected for two things have to be true:
1. It must increase the fitness of the organism that carries it, i.e. the likelihood of its carrier having descendants as compared to non-carriers ( or be a side effect of another feature that improves fitness enough to be a net positive, etc etc )
2. It must be inheritable (and, in sexually reproduced organisms, mutually compatible during embryonic development).
One such a feature has reached dominance in a given population, as long as it continues to be important for fitness it cannot really be deprecated in favour of an alternative from scratch, even if that alternative is arguably better.
That's why, for instance, vertebrate ocular nerves connect to our retinas on the inside of our eyeball, resulting in us having a blind spot. Cephalopods, on the other hand, evolved their eyes independently the "reasonable" way, connecing their nerves from behind the eyeball. There's no way a vertebrate could mutate from scratch for its optical nerve to connect to the retina from behind without causing absolute mayhem in embryonic development. Our hacky solution for the blind spot? Let the brain hide it in software.
Going back to your question, some spots of the body being more sensitive than others became critical for evolutionary fitness long before nervous systems were complex enough to generate conscious qualia, let alone enough for them to be consistently involved in decision making. Furthermore, mapping of specific nerves to intensity of feeling on the CNS would imply complex hardcoding of something which is much easier to solve with "this place important, have more nerves", and maybe would even conflict with the fitness benefit of a CNS with enough neuroplasticity to learn anew during the development and lifetime of an organism.
So, in summary, the solution of having more nerves where it matters is simple, good enough, and has no reason to be rolled back in favour of a radically different alternative.
As a software dev, I think this is actually quite a satisfying and sensible answer. A simple reliable hardware solution in favour of a brittle “clever” software one
Having more independent samples helps filter out noise. If you had individual sensory neurons with outsized influence, then misfiring of such neurons would also have outsized influence.
Sounds plausible at least, but I think the question isn't necessarily making a valid assumption. Why do men have to have nipples? Why is our retina installed backwards? Why do sinuses drain upwards? It's just a path evolution took, it doesn't jump to some optimal design.
male nipples are developmental vestiges, the male condition is derived from response to embryonic testosterone, and is a developmental variation from default.
early stage embryos of both sexes are not easily distinguishable by genitalia, they look morphologically similar. later developmental events culminate in morphological rearrangement to male form.
lack of response to testosterone during development results n a curious state of affairs, where a person is genetically male, having x, and y chromosomes, develops according to a female plan. external appearances are female, with loss of secondary sex development in puberty.
> Dumb question, why do “sensitive” spots on the body need more nerves? Couldn’t you just have the normal touch-sensing nerves and map signals from specific spots on the body to stronger/pleasurable qualia in the brain?
Think of a television. What gives you a better picture, quadrupling the number of pixels or making the existing pixels 4x as intense?
Fingers, for instance, not only have higher sensitivity, but also much higher spatial resolution due to the more dense nerve network.
I can't tell why other areas may have needed higher spatial resolution; maybe it was evolutionary important in the past, and remains today. Or maybe just adding more nerves due to a random mutation correlated with better reproductive outcomes due to a stronger signal, or higher sensitivity, so more nerves are present for no other reason.
I remember that Matteo Realdo Colombo (1515-1559) [1] described the clitoris. There is a novel about the story [2] which was the finalist on one of the top Spanish literary prizes [3].

Bias towards women would be understood by most readers as favouring them. I would have written bias against women here.

What’s your best source that African FGM is about enhancing female sexual pleasure, specifically for oral sex?

Male genital mutilation is very common
Respectfully, this article is not about the male experience, it's okay to talk about women without putting men in the story.
No, it's important context, and attempting to suppress it does everyone a disservice.

Androgen insensitivity syndrome:

Asking “why” questions about our body / evolution often (not always) gives informative answers. As in the example you gave: https://www.scientificamerican.com/article/the-purpose-of-ou...
Interesting finding, though it doesn't explain animals with properly-wired retinas: https://en.wikipedia.org/wiki/Cephalopod_eye
(Scientific American is throwing up a paywall even though they're only republishing https://theconversation.com/look-your-eyes-are-wired-backwar... At least they link to the original.)
Correct, though interestingly apropos to the discussion is that sex is one of the ways evolution is able to get around local maximums.

Perhaps encoding "software" is more expensive in terms of codons? So it's cheaper/more likely to "implement" physically.
