Sources
The novel. Ursula K. Le Guin, The Left Hand of Darkness (1969). Source of spreads seven and eight: somer and kemmer; “The king was pregnant” and the Gorinhering clansmen laughing because Argaven is too old; Genly Ai’s note that “the distinction between a maternal and a paternal instinct is scarcely worth making; the parental instinct, the wish to protect, to further, is not a sex-linked characteristic”; and Tormer’s Lay in chapter 16, Between Drumner and Dremegole, together with the sentence that follows it — Estraven remembering that his dead brother had quoted the same words. All read at the novel, not at a quotation site. The Lay is very widely reproduced without its next sentence; we have printed the next sentence because it changes what the poem is.
The essay, and the corrections. Ursula K. Le Guin, “Is Gender Necessary? Redux” (1976/1987), in Dancing at the Edge of the World: Thoughts on Words, Women, Places (Grove Press, an imprint of Grove/Atlantic, 1989), ISBN 978-0-8021-3529-2. The 1976 essay first appeared in Aurora: Beyond Equality, edited by Susan Janice Anderson and Vonda N. McIntyre, and was reprinted in The Language of the Night. Source of spread nine: the headnote on not obliterating an old text and on clams that don’t open; her request that anyone quoting the piece include the reconsiderations; and the bracketed annotations — the collapsed “utter refusal,” [I now consider it very important.], the regret about locking the Gethenians into heterosexuality, [strike “his”] and [place “him” in quotation marks, please]. Every one of these was read at the book, from Ryan’s own copy, after a full-text reproduction had been rejected as insufficient for a title.
Sex change, both directions. Hans W. Fricke & Simone Fricke, “Monogamy and sex change by aggressive dominance in coral reef fish,” Nature 266, 830–832 (1977) — protandry in anemonefish and the dominance hierarchy that drives it, spread three. Erica V. Todd and colleagues, “Stress, novel sex genes, and epigenetic reprogramming orchestrate socially controlled sex change,” Science Advances 5(7), eaaw7006 (2019), doi:10.1126/sciadv.aaw7006 — source of spread four: male behaviour within hours, ovary to functional testis in eight to ten days, sperm inside twenty-one, methylation at aromatase, and the intermediate state resembling early developmental cells.
How many kinds there are. Erika Kothe, “Tetrapolar fungal mating types: sexes by the thousands,” FEMS Microbiology Reviews 18(1), 65–87 (1996), and the subsequent Schizophyllum literature, for the four-locus system and the roughly 9 / 32 / 9 / 9 allele counts. The “more than 23,000” on spread five is a product of those counts, not a headcount, and it moves as more alleles are described — we have said so on the spread. Tetrahymena thermophila’s seven mating types and isogamy in green algae are standard, long-established results and are used here as such.
The price of male pregnancy. Olivia Roth and colleagues, “Evolution of male pregnancy associated with remodeling of canonical vertebrate immunity in seahorses and pipefishes,” PNAS 117(17), 9431–9439 (2020), doi:10.1073/pnas.1916251117, for the loss of the MHC class II pathway; and the syngnathid immunogenetics literature for the loss of TLR1, TLR2 and TLR9 and for brood-pouch structure. Spread six.
The correction to my own reading. Maud Mouginot and colleagues, “Differences in expression of male aggression between wild bonobos and chimpanzees,” Current Biology 34 (2024), doi:10.1016/j.cub.2024.02.071 — twelve male bonobos at Kokolopori against fourteen male chimpanzees at Gombe over two years; ~2.8× the aggressive encounters and ~3× the physical ones; higher male-male and female-male rates; the mating-success correlation and the two males siring 80 per cent of the sampled offspring; and the persistence of the real difference, that lethal aggression is absent. Spread ten.
Everything else on spread twelve. Lindsay C. Young, Brenda J. Zaun & Eric A. VanderWerf, “Successful same-sex pairing in Laysan albatross,” Biology Letters 4, 323–325 (2008), doi:10.1098/rsbl.2008.0191 — 31 per cent of pairs female-female at the Oahu colony, against a 59 per cent female sex ratio driven by female-biased immigration, and fewer fledglings than male-female pairs but better than not breeding. David Crews’ work on parthenogenetic Aspidoscelis for courtship and pseudocopulation raising egg production. Bruce Bagemihl, Biological Exuberance: Animal Homosexuality and Natural Diversity (1999), for the 450-species figure on spread eleven; its citation in amici in Lawrence v. Texas (2003) is a matter of record.
The words. Neuroqueer — Nick Walker, independently Athena Lynn Michaels-Dillon, with Remi Yergeau’s work alongside; Walker, Neuroqueer Heresies (2021). Autigender — deliberately logged as unsourced. The widely quoted definition is a Candidly Autistic Tumblr post of 2017, surviving in the Internet Archive; the coinage is generally traced to two Tumblr accounts posting via mogai-archive in August 2014, attested only in community-maintained wikis, which are leads and not citations. We have not upgraded it, and spread thirteen says why. Our own longer treatment of both words is at stimpunks.org.
What this deliberately does not re-argue
The two words have their own page and it is not this one. Autigender and neuroqueer are set out at length on stimpunks.org, from 2022. Spread thirteen carries only what belongs to this argument — where the words came from, and what it means that one of them cannot be cited.
The paradigm is spent elsewhere. No. 11 and No. 8 carry the difference-first case; the neurodiversity field guide carries the definitions. Spread twelve leans on all three rather than rebuilding them.
The companion catalogue. A Field Guide to the Sexes (Field Guide No. 24) is the organisms at length — nineteen of them, sorted by which of the model’s five bundled assumptions each one takes apart, plus two cards that get no reframe table because one reports an open problem and the other is about people. It carries the same refusals as this zine and repeats none of the argument.
A rhyme, not a proof. Nothing in the natural history here is evidence about human lives, and the zine says so in six different ways because that is the single mistake this subject invites. What the organisms establish is narrow and factual: the claim that there is one arrangement, and that it is what life is, does not survive contact with life. Everything after that — consent, tenderness, honesty, who gets hurt — is ours, and no fish has a view.
