  • Theoretical biologist here. I consider viruses to define the lower edge of what I’d consider “alive.” I similarly consider prions to be “not alive,” but to define a position towards the upper limit of complex, self-reproducing chemistry. There’s some research going on here to better understand how replication reactions (maybe encased in a lipid bubble to keep the reaction free from the environment) may lead to increasing complexity and proto-cells. That’s not what prions are, but the idea is that a property like replication is necessary but not sufficient and to build from what we know regarding the environment and possible chemicals.

    I consider a virus to be alive because they rise to the level of complexity and adaptive dynamics I feel should be associated with living systems. I’ll paint with a broad brush here, but they have genes, a division between genotype and phenotype, the populations evolve as part of an ecosystem with all of the associated dynamics of adaptation and speciation, and they have relatively complex structures consisting of multiple distinct elements. “Alive,” to me, shouldn’t be approached as a binary concept - I’m not sure what it conceptually adds to the discussion. Instead, I think it should be approached as a gradient of properties any one of which may be more or less present. I feel the same about intelligence, theory of mind, and animal communication.

    The thing to remember when thinking about questions like this is that when science (or history or literature…) is taught as a beginner’s subject (primary and secondary school), it’s often approached in a highly simplified manner - simplified to the point of inaccuracy sometimes. Many instructors will take the approach of having students memorize lists for regurgitation on exams - the seven properties of life, a gene is a length of dna that encodes for a protein, the definition of a species, and so on. I don’t really like that approach, and to be honest I was never any good at it myself.






  • There’s entire branches of research on this, but I think one of the easiest ways to approach it for starting out is to think of the word “womanly.”

    having or denoting qualities and characteristics traditionally associated with or expected of women.

    I would strike the word “traditionally” from that definition since we’re talking about a comparative and differential analysis and concentrate on the “qualities and characteristics” part. Although most people in the US today wouldn’t think of it this way, imagine the perception of a woman army officer commanding male troops in 1845. You can take the same approach when looking through history or across cultures. What roles, qualities, and characteristics are associated with “women” and how do they differ and evolve?

    There’s some complexity when you get into the details - indigenous cultures change when they come into contact with, say, colonialism, and the people who studied them might themselves be observing through their own prejudices. History is replete with examples of British colonialists being unable to properly deal with things like the egalitarian democracies of the northern indigenous peoples or the matriarchal social structures. Picture the used car dealership where the salesman still insists on engaging with the man even though it’s the woman buying the car.

    Semantics is the study of the meaning of words, and semiotics is the study of symbology. When we’re talking about these things, we’re talking about how the ideas and symbols associated with the idea-token “woman” differ.

    The reason why this is important is that this is the crux of the transphobic argument. Their argument is cultural, not biological (although like I said, even their biology is sketchy).

    I think a great study that includes cross cultural anthropological analysis of the role of women, as well as politics and economics, is David Graeber’s The Dawn of Everything.



  • Biologist here. The main problem with this argument is that Rowling is trying to win her argument through scientizing, and is not only doing it in an inept way, but in a way that’s completely ironic.

    She’s invoking biology, but infortunately she’s adopting an approach that incorporates a high school level of biology. When we start teaching science, we start with highly simplified presentations of the major topics, then build both in breadth and depth from there. If you really want to get down the rabbit hole of sex determination (and multiple definitions of genetic and phenotypical “sex”), you really need to get into molecular biology, genetics, and developmental biology. She’s been advised of this multiple times by multiple experts, so at this point it’s willful ignorance.

    The painfully ironic part is that she’s relying on an area where she has no expertise in order to make her point, while ignoring the fact that, as a world-known literary figure, she should know that the applicable part of the definition of “woman” is linguistic and semiotic - which is to say it’s cultural. The definition of “woman” was different in the 1940s South, among the 17th century pilgrims, the Algonquin tribes, cultures throughout sub-equatorial Africa, and so on.


  • Yes, but at the same time no imho.

    Authors of later books absolutely had access to the works of earlier authors. It wasn’t “the Bible” as we know it today, but there is a direct lineage where new material has been added and existing material has been edited, to result in the book we have now. That’s why the character of Jesus was able to fulfill prophecies.

    So I’d tend to define “the bible” as a collection of literary works and interpretations (I don’t think you can separate the two without losing significant meaning) that evolves over time. Evolutionary pressures can include how well a particular “species” serves the rulers at that time, and how well it fits with the general zeitgeist (eg apocalyptic or euphoric).

    So, like Trump, they didn’t have “the bible” but they had “a bible.”


  • Lemmy is small enough that “brigading” doesn’t feel entirely appropriate. Maybe “platooning?”

    In any case, we know from other sites that downvotes increase the probability of getting more downvotes, and nasty comments increase the probability of getting more nasty comments. The same goes for upvotes and positive comments. It’s just social dynamics. Some subs on reddit existed almost exclusively to call out other subs, but I think that Lemmy’s user base is small and spread out enough that it’s not a major contributing factor in voting.

    I think it’s mostly just people scrolling along, running across a hot take, and interpreting it according to the voting.

    In any case, I would suspect that people would be more impacted by hurtful comments than downvotes.

    Here’s the thing. You said a “jackdaw is a crow.” Is it in the same family? Yes. No one’s arguing that. As someone who is a scientist who studies crows, I am telling you, specifically, in science, no one calls jackdaws crows. If you want to be “specific” like you said, then you shouldn’t either. They’re not the same thing. If you’re saying “crow family” you’re referring to the taxonomic grouping of Corvidae, which includes things from nutcrackers to blue jays to ravens. So your reasoning for calling a jackdaw a crow is because random people “call the black ones crows?” Let’s get grackles and blackbirds in there, then, too. Also, calling someone a human or an ape? It’s not one or the other, that’s not how taxonomy works. They’re both. A jackdaw is a jackdaw and a member of the crow family. But that’s not what you said. You said a jackdaw is a crow, which is not true unless you’re okay with calling all members of the crow family crows, which means you’d call blue jays, ravens, and other birds crows, too. Which you said you don’t. It’s okay to just admit you’re wrong, you know?
