One by one, biology journals—and other science journals, as noted in our new “merit” paper—are placing at the top of their priority list “progressive” authoritarian Social Justice, often presenting misguided science because it comports better with progressive ideology.
Here we see another journal voluntarily leaping down the rabbit hole: BioScience, published by the American Institute of Biological Sciences. I found this out because a colleague and I wrote a perfectly civil letter to the editor in response to a big paper about how to present “inclusive” biology in the classroom. The editors accepted and published our letter, and I thought that would be the end of that. A normal scientific exchange.
Oy, was I wrong: nothing is “normal” when sex and gender ideology are at stake.
First, the editors allowed the authors of the original paper to respond, which is perfectly normal in the literature—except they gave them twice as much space as they allowed us. Well, that’s okay, too; I’m not going to beef much. But THEN three of the journal’s editors—the editor-in-chief, the senior editor, and then the “past editor in chief” (?)—wrote a joint op-ed opening the journal, whose purpose was not only to flaunt virtue and show how devoted the journal was to inclusivity, but also to spank my coauthor and me for what we said in the very letter that the journal accepted. Talk about overreaction! But it’s in the interest of the journal and its associated society to assert ideological purity, so the editors just had to weigh in.
Fortunately, all the papers, letters, and op-eds are online and accessible below, so you can judge for yourselves. I’ll put each step in the sequence of four publications:
a.) Zemnick et al. wrote a long paper about how to teach biology in college in a way that would “embrace gender and sexual diversity” among the students. Their outline of teaching rules (I’ll mention only one) was intended to convince students who were either trans or of diverse genders that their behavior was not “unnatural.” To do this, they recommended to begin biology courses by teaching the diversity of sexuality in the animal kingdom so that gender diverse students could be heartened by seeing that they weren’t something outside of nature.

The main problem with the piece, which of course was motivated by empathic concerns, is that the authors propose a teaching method that relies on the naturalistic fallacy, the idea that if something is natural is must be “good”. (I use “good” here in the sense of the sexual identity of a student, which is to be buttressed by the authors’ pedagogy.) But then they vehemently deny that they’re using the naturalistic fallacy.
Their aim:
In the present article, we focus on teaching approaches aimed at inclusivity related to gender and sexual minorities. Broadly, we include lesbian, gay, bisexual, transgender, queer, intersex, asexual, and two spirit people, as well as identities that do not fit neatly into those labels (LGBTQIA2S+) to fall under the umbrella of gender and sexual minorities, and the needs of this population are the focus of this article. We acknowledge that LGBTQIA2S + students are not a homogenous group and that the students’ needs will also depend on race, class, disability status, and other identities.
Despite advancements in recent decades, sexual and gender minorities face considerable obstacles and inequities in scientific culture. Undergraduate students belonging to sexual minorities are less likely to complete their STEM degrees than their heterosexual peers (Hughes 2018). Many LGBTQIA2S + scientists consider quitting their jobs because of harmful workplace climates (Gibney 2019) and are more likely to intend to leave STEM altogether than are their peers (Cech and Waidzunas 2021).
I’d urge you to check out the references. For example, Hughes 2018 says this:
This interaction term was significant: sexual minority men’s expected probability of retention in STEM was lower than that for heterosexual men (0.45 versus 0.54), whereas sexual minority women’s expected probability exceeded that of heterosexual women (0.39 versus 0.32).
That is, being a sexual minority woman actually increases your probability of staying in STEM—just about as much as it lowers men’s probability. This isn’t mentioned, nor does the original study control for other variables, like psychological issues, that may influence dropping out of STEM independent of any bigotry or lack of inclusivity.
But I digress. The teaching method proposed by Zemenick et al. has six components. Here’s the first one.
. . . For many topics, instructors must make decisions about how to simplify biological complexity so that it can be understood by students. A common strategy is to focus on a simple and general biological “rule” first, and then, if time allows, discuss “exceptions to the rule” only after the basic pattern has been established. For example, when discussing sex determination, educators might begin and end with a simplified discussion of developmental pathways in humans and animals with XY determination systems. Intersex and other developmental pathways (e.g., Bachtrog et al. 2014), if they are discussed, are presented as deviations from the norm, and, in humans, are often unnecessarily pathologized.
We propose presenting diversity within and across species first as opposed to last. This can help avoid the misconception that the average or most common phenotypes in one taxa, species, or population is what is “natural” or “normal” among all populations or species. By presenting diversity first, students learn that variation and diversity in sexual reproduction strategies, sex determination systems, and sex-associated behaviors is vast and normal; in other words, diversity the biological rule, not the exception!
. . . Presenting diversity in the class can have three main benefits. First, it can help normalize human diversity in the classroom. Students may be more able to understand why there is so much variation in humans and that there is nothing fundamentally “unnatural” about not fitting into narrow cultural norms of gender identity, behavior, or sexuality.
. . . Biology classrooms represent powerful opportunities to teach sex- and gender-related topics accurately and inclusively. The sexual and gender diversity displayed in human populations is consistent with the diversity that characterizes all biological systems, but current teaching paradigms often leave students with the impression that LGBTQIA2S + people are acting against nature or “basic biology.” This failure of biology education can have dangerous repercussions.
If that isn’t the naturalistic fallacy (or the related appeal-to-nature fallacy), I don’t know what is. Now the authors do claim that they’re not adumbrating either fallacy, but this seems to be a confusion on their part. By teaching “diversity first”, their explicit aim is to show LGBTQIA2S+ students (lesbian, gay, bisexual, transsexual, queer, intersexual, asexual, and everything else under the “+” ) that their diverse sexuality is not at all unnatural, because animals show similar “diversity” (they don’t, of course; see below).
Here’s their caveat, which we found unconvincing:
A second potential concern is that this principle, if it is simplistically applied, will perpetuate the appeal-to-nature fallacy—that is, the argument that anything found in nature is inherently good (Tanner 2006). This is problematic, because it can suggest that students need examples of specific behaviors or biologies in nature to validate human experiences or, alternatively, that anything found in nature is justified in humans. We emphasize that presenting diversity first should only demonstrate that we should expect diversity, including among humans, but this does not present a value argument. Rather, it combats the incorrect assumption that nonbinary categorizations, intersex characteristics, same-sex sexual behavior, transgender identities, gender nonconforming presentation and behavior, and so on are unnatural, which is, itself, often used against LGBTQIA2S + people in an appeal-to-nature argument (e.g., Newman and Fantos 2015).
This seemed to me and my colleague Nelson Fagundes deeply confused. The authors say it’s not a value argument, but then assert that showing biological diversity tells students that their behavior is “natural,” and combats arguments against diverse sexuality based on its supposedly being “unnatural.” This is cognitive dissonance, and of course I’ve battled this kind of argument for years, as you can see in one paragraph I wrote below.
b.) A colleague and I write a response in BioScience. Nelson Fagundes, a Brazilian biologist, was also concerned by this paper, and asked if I wanted to collaborate with him on a letter to BioScience. I did, and so we wrote a letter to the journal, reproduced in indented form below the screenshot. Click on the screenshot to see it, or find the pdf here.

Here’s our published letter (493 words; we were told not to exceed 500 words). Note the paragraph in bold, which came from a review I did of Joan Roughgarden’s book Nature’s Rainbow.
Few sentences capture so aptly the awe biologists feel toward nature as does the final passage of On the Origin of the Species (Darwin 1859): “From so simple a beginning, endless forms most beautiful and most wonderful have been, and are being, evolved.” Indeed, biologists are trained to study—and wonder at—the almost infinite diversity of life forms. In a recent essay, Zemenick and colleagues (2022) discussed how we should promote a more inclusive and welcoming environment for biology teaching, including LGBTQIA2S+ students, and suggested six general principles for achieving this goal. Although we agree with most of their principles, we would like to add one: Teach the naturalistic fallacy first.
Zemenick and colleagues (2022) stated that many students may feel uncomfortable if their bodies, gender, or sexual orientation are depicted as “unnatural.” Even though the authors seem to recognize the perils of the naturalistic (or appeal-to-nature) fallacy—the idea that what is natural is inherently good or should dictate our behavior—they suggest instead that we should teach “diversity first,” giving students a broad array of biological examples to show that there is nothing “unnatural” about not fitting traditional cultural norms about sexuality or gender.
Well intentioned as this suggestion may be, our opinion is that it actually caters to the naturalistic fallacy by promoting positive “natural models” of sexual or gender behavior. But most philosophers and rationalists have recognized that nature is incapable of providing a moral guide or role models for humans (Tanner 2006). For example, whether or not animals have gender is irrelevant to a moral discussion about human gender roles. In addition, lethal aggression, sexual coercion, and infanticide not only exist in nature but represent adaptive strategies. Surely, we cannot just pick out the “good” diversity of nature as a model while ignoring the equally adaptive “bad” forms of diversity. Furthermore, if ethics or rights depend on observations of nature, then those values become susceptible to change if our understanding of nature changes.
Culture, rights, ethics, and moral equality are phenomena unique to our species. As one of us wrote about the perils of using nature to draw lessons about human behavior,
“Given the cultural milieu in which human sexuality and gender are expressed, how closely can we compare ourselves to other species? In what sense does a fish who changes sex resemble a transgendered person? The fish presumably experiences neither distressing feelings about inhabiting the wrong body nor ostracism by other fish. In some baboons, the only males who show homosexual behavior are those denied access to females by more dominant males. How can this possibly be equated to human homosexuality?” (Coyne 2004)
Emphasizing the problems of the naturalistic fallacy would show students that they do not need to find examples in nature to affirm their genders or sexual identities. Instead, their identities should be respected based on human rights (OHCHR 2019). Nature cannot be—and should not be—any guide to human rights and morality.
This shows the profound fallacy of trying to buttress people’s identities, sexual or otherwise, by showing them the diversity of nature. For some of that diversity could be used to show that all kinds of nefarious behavior in humans is also “natural”, including infanticide, murder, necrophilia, and theft. Here’s another paragraph from my review that we didn’t reproduce.
But regardless of the truth of Darwin’s theory, should we consult nature to determine which of our behaviours are to be considered normal or moral? Homosexuality may indeed occur in species other than our own, but so do infanticide, robbery and extra-pair copulation. If the gay cause is somehow boosted by parallels from nature, then so are the causes of child-killers, thieves and adulterers.
Do Zemenick et al. want to teach that kind of diversity? I don’t think so. They want to teach only the kind of diversity that buttresses their ideology [and own sexual identities, see the postscript below]. This is not biology instruction, but ideologically-motivated propaganda.
I thought this exchange was pretty anodyne, and that our letter would be the end of it. But that doesn’t seem to be the case when biologists promote “progressive” views, and so. . . .
c.) The authors respond to our letter. Click screenshot below to see it, or read the pdf here. The authors got 973 words to respond, just about twice what we were allowed. So be it.

Their main point is to assert that they took care to prevent raising the naturalistic fallacy, quoting the caveat in their original paper. They then go ahead and reprise that same fallacy by reiterating what they said in their original article:
Therefore, our article is in alignment with the need to avoid the naturalistic fallacy, which we argue can be effectively done in conjunction with a diversity-first model of teaching. Second, Fagundes and Coyne misunderstand our article as arguing that educators should make moral arguments based on the natural world in an effort to combat the perception that LGBTQIA2S+ students are morally wrong. In fact, we argue that educators should use a diversity-first model not to combat the perception that sexual and gender diversity is morally wrong but the perception that it is “unnatural.” We are concerned that traditional biology education models can lead students to infer their bodies or experiences are not part of the natural world, that they are an anomaly or something biological science cannot explain. As such, biology education should aim to impress on students that diversity and variation are the norm in biology, not to teach them about “good” (or “bad”) diversity.
As we state in our original article, in biology, course content provides opportunities to challenge harmful preconceptions about what is “natural” while avoiding the notion that anything found in nature is inherently good (the appeal-to-nature fallacy). A risk in biology education is that LGBTQIA2S+ students will feel unnatural, erased, or invisible or that they will be unable to align their realities with their understanding of biology (Amarati Casper et al., 2022).
. . . Finally, although students may not need to find examples in nature to understand their own biology—they are already valid because they exist—they can benefit from such examples. We have found that, without relying on the naturalistic fallacy, showing students examples from biology can give some students comfort, curiosity, and joy by illustrating they are part of a universal pattern of biological diversity.
Translation: “Students don’t need examples from nature to buttress their sexuality, but it’s way better if they get the examples, and we recommend providing them.” To me this bespeaks a deep confusion on the part of Zemenick et al. And of course if this is your aim, then it helps determine what kind of biological examples you’ll use.
But that response was apparently insufficient for the journal’s editors (who accepted our letter).
d.) Three BioScience editors decided to double down and publish an editor’s op-ed at the beginning of the journal, taking us to task and giving us an editorial potsch in tuchas. You can read the Big Editorial below by clicking on the screenshot, or get the pdf here. This response amused me, except for the editors’ denial (see below) that sex is binary in nature. Here we see a blatant distortion of the facts in the service of ideology, and it’s made by the editors themselves.

I’ll be brief. They reiterate Zemenick’s claim that we got the original paper wrong because Zemenick et al. denied using the naturalistic of appeal-to-nature fallacy. Ergo our criticism was misguided. I’ll give one quote and then a corrective:
Although Zemenick and colleagues were clear to place diversity as the primary reason and method to make the classroom more inclusive, rejecting nature-based arguments as moral guides, it seems that Fagundes and Coyne failed to see this message. It is worth reiterating that the key point of contention is that natural models cannot serve as or provide “moral guides or role models for humans.”
No, the main point is that you should not look to nature to buttress human identities or behavior, for that is a slippery strategy—a two-edged sword. Zemenick et al. did in fact use natural variation as a form of moral guidance: a way to show students that their behavior wasn’t wrong or immoral because, after all, we see it in the “diversity of nature.” (If you can show me a natural analogue of gender dysphoria leading to medical sex change in nature, let me know.)
But the most disturbing part of the editors’ screed comes right after the bit above, and it’s this (bolding is mine):
We do believe that we can learn much about ourselves through the study of related animals. Humans are products of evolution. Evolution works on variation. The binary concept of sex and sexual behavior is counter to the variation we see around us.
No, sexual behavior is not binary, but it’s bimodal in general, with males being promiscuous and females choosy. The bad part is the editors’ palpably false assertion that “The binary concept of sex is counter to the variation we see around us.” Really? Have they looked around themselves? So here’s another incipient letter to the editors:
Dear BioScience editors:
Sex in animals and nearly all vascular plants is binary: males with the equipment to make mobile gametes and females with the equipment to make large immobile gametes. Are you denying this? If not, then please publish a correction, for your statement is damaging the public understanding of biology.
Sincerely,
Jerry Coyne
Yes, sex is binary, and it does no credit to the editors of this journal to deny that in the interests of ideology. And make no mistake about it: this editorial is buttressed by ideology. Here’s the ending:
Although the study of nature may not provide moral direction, as scientists or science facilitators, we cannot escape the higher obligations of knowledge discovery to which we knowingly commit. Embracing all aspects of moral excellence, including the ways that we treat others, is an essential standard of science. Third, if the American Institute of Biological Sciences has made inclusiveness and diversity the foundation of its organizational blueprint, then we can surely embrace higher diversity concepts in our classrooms. We encourage you to thoughtfully read and consider implementing the suggestions found in Zemenick and colleagues’ original article, and we look forward to reading about the effectiveness of such endeavors, hopefully in the pages of BioScience
Here they explicitly place MORAL OBLIGATIONS as not only an “essential standard of science,” but also assert that “inclusiveness and diversity” is “the foundation of [The American Institute of Biological Science’s] organizational blueprint.” Whatever happened to making the main purpose of biology organizations to teach and promulgate biology?

POSTSCRIPT: After I finished this draft, I looked up who the authors of the original paper were (they’re at the end of the references in the pdf file, so I hadn’t seen them). And, lo and behold, here are the authors’ “positionality statements”. They don’t affect my arguments at all, but may explain the thrust of the original paper and the doubling-down by the editors.
Author Biographical
Ash T. Zemenick is a nonbinary trans person who grew up with an economically and academically supportive household to which they attribute many of their opportunities. They are now the manager of the University of California Berkeley’s Sagehen Creek Field Station, in Truckee, California, and are a cofounder and lead director of Project Biodiversify, in the United States. Shaun Turney is a white heterosexual transgender Canadian man who was supported in both his transition and his education by his university-educated parents. He is currently on paternity leave from his work as a non–tenure-track course lecturer in biology. Alex J. Webster is a cis white queer woman who grew up in an economically stable household and is now raising a child in a nontraditional queer family structure. She is a research professor in the University of New Mexico’s Department of Biology, in Albuquerque, New Mexico, and is a director of Project Biodiversify, in the United States. Sarah C. Jones is a disabled (ADHD) cis white queer woman who grew up in a supportive and economically stable household with two university-educated parents. She is a director of Project Biodiversify, and serves as the education manager for Budburst, a project of the Chicago Botanic Garden, in Chicago, Illinois, in the United States. Marjorie G.

I don’t think these positionality statements are either necessary or relevant unless you’re into politics or psychology. Authors’ arguments, whether about pedagogy or science, should be judged on their own merits, regardless of the arguers’ identities.
Finally, this post represents my own views, not those of Dr. Fagundes, though I suspect he’d agree with many of them!
