Animals' shared ancestor with fungus is thought to be among https://en.m.wikipedia.org/wiki/Choanoflagellate, which kinda look like sperm.

My guess is that they were predominantly haploid (like sperm/eggs), and just had a diploid (like most other human cells) phase for reproduction. Somewhere along the way this switched (which is thought to have happened in plants also, mosses are primarily haploid while flowering plants are primarily diploid).

...which is totally bonkers. It's like if sperm/eggs went around making all of the important decisions and only bothered to spin up a human briefly for reproductive purposes. But then the sex got a bit out of control and got a job and an apartment and now it's the sperm who look like they're just for reproduction.

Disclaimer: I took Bio 101 two semesters back, so I'm pretty much an expert.

> It's like if sperm/eggs went around making all of the important decisions and only bothered to spin up a human briefly for reproductive purposes.

That's very close to the thesis of Richard Dawkins' seminal book, the Selfish Gene--we're just machines constructed by genes to replicate them. It's literally true, of course, but we don't often take that perspective; yet many things in biology aren't intuitive unless and until we do.[1]

[1] OTOH, some things in biology become inexplicable when we do take that perspective, such as non-kin altruism. IIRC, Dawkins admits as much in the book. (Contra some subsequent sociopolitical interpretations, Dawkins never used his "selfish gene" model to refute the possibility of non-kin altruism, just that the model in isolation was insufficient to explain non-kin altruism, the existence of which he seemed to take for granted, at least in humans.)

A company I was at renamed master to main to avoid implications of human slavery when committing to source control.

I've experienced similar. Sure, words matter. But so does context, at least it should.

And yet I bet those you make the suggestion still say "master bedroom" (which actual is a direct reference to slavery).

Re:What You Don't Know About Sperm by b4ke on Saturday January 06, 2024 @05:57AM (#38890363)
American home ownership is so loaded with plantation era subtle subjugation in the form of linguistic convention. If master bedroom were the worst it would get attention.

I switched to originating new repos as main instead of master personally, reinforcing the concept of “commuting to” or code “being committed” to “master”, seems diametrically opposed to progress.

In San Francisco, when I was looking for a new place to rent in 2022, the realtor would use the phrase "primary bedroom" instead, remarking that apparently people in the field are moving away here from "master" because of the connotation.

Personally, my favourite is this Github repo https://github.com/queer/boxxy

The primary branch is called "mistress". haha, that's good

On the flip side, there are also cases where some changes to the language make things more obvious and simple. As a non-native English speaker, allowlist/denylist make more sense to me than whitelist/blacklist, since allow/deny describe the purpose well, as opposed to white/black.

As for having a "main" branch or other things like that, I don't really mind the change much. Admittedly, both the claims about implications surrounding slavery and counter-arguments regarding names like having a "master record" seem overblown to me (on one side, why care about some obscure software term instead of trying to effect actual change? on the other, why push back against a trivial change so much, it's not like using a different term is so hard if it pleases a lot of people?), although perhaps due to me not having the heritage of the people in the US, so I just quiet down and do the sensible thing.

Re:What You Don't Know About Sperm by j4yav on Saturday January 06, 2024 @07:34AM (#38890923)
I didn’t push back or complain, but I don’t really get the victory they think they achieved there. Definitely nothing that helped an actual living person improve their life - donating the equivalent in salary spent working on the change to local families would have been more effective at making the world a better place imho. There were no theoretically impacted people championing or asking for the change. It was just some people looking for something to do, and they even had a celebration at the end like they really achieved something.

Because it’s the same group of people who want to, on a whim, decide that “homeless” is now “houseless” and that it’s offensive to homeless people to call them anything else. It’s language authoritarianism used to arbitrarily paint people as bad for utilizing common verbiage and for the dictators to feel they’re some revolutionaries all while never doing anything to actually help the people they claim to be fighting for.

Isn't non kin altruism just prisoners dilemma part of the evolution? E.g. groups that work together will survive and genes of these groups will get passed on. So the desire is to help any friendly individuals, but it also works globally because this hasn't really even been part of evolution to be so globalized.
Re:What You Don't Know About Sperm by colechristensen on Friday January 05, 2024 @09:46PM (#38887850)
Not exactly, but also yes. There is a game being played where there are local optimums of a ratio of cooperating/betraying and evolutionary pressure against the “wrong” ratios. There is also the problem of it being difficult or too resource intensive to have perfect knowledge of what other individuals actually share your genes and by how much and some group altruism is explained by evolution taking shortcuts that work well enough.

The point of the book is that the mechanism explaining such things shouldn’t stop at “because it’s good for the group” instead digging down into why what’s good for the genes must explain the higher order behavior.

Re:What You Don't Know About Sperm by wegfawefgawefg on Saturday January 06, 2024 @08:32AM (#38891281)
non-kin altruism could just be a mistake. A behaviour intended to be applied to ones own species, but ends up applied to others because of the detectors used to identify another agent not being scrutinous enough.

Just because you get diabetes doesnt mean its the intended behaviour of evolution. Could be a spandrel, or an artifact, or aliasing, or a plain mistake.

Re:What You Don't Know About Sperm by anigbrowl on Friday January 05, 2024 @06:51PM (#38886701)
I'm something of a scientist myself*, and every time I delve into cellular biology I find myself wondering if there is a primitive consciousness on the cellular level, because lives of many cells are complicated.

Consider Memory B cells, which are formed early during foetal development. They hang around in the body for years - sometimes decades - looking out for new and unusual pathogens. When they encounter one, they internalize the peptides and then (typically, but not always) rush off to a germinal center to help manufacture new T cells that can recognize and defeat the unwanted interloper. then the B cells leave again and go back to their vigil.

https://en.wikipedia.org/wiki/Memory_B_cell

Conversely, when you look at the dynamics of large groups, organizations, and corporate entities (institutions as well as business, up to whole nations), it's hard not to see them as organisms in their own right that have a sort of meta-consciousness independent of their component humans.

Information Closure Theory of Consciousness (2020) https://www.researchgate.net/publication/342956066_Informati...

> However, only information processed at specific scales of coarse-graining appears to be available for conscious awareness. We do not have direct experience of information available at the scale of individual neurons, which is noisy and highly stochastic. Neither do we have experience of more macro-scale interactions, such as interpersonal communications. Neurophysiological evidence suggests that conscious experiences co-vary with information encoded in coarse-grained neural states such as the firing pattern of a population of neurons. In this article, we introduce a new informational theory of consciousness: Information Closure Theory of Consciousness (ICT)

Isn’t another explanation that they travel in such large amounts they will eventually interact with the right system due to chemical interactions? That is the right proteins will activate the right channels eventually when you have hundreds of thousands of attempts? I don’t think they are conscious in the sense they are driving along a road and know where to turn. It’s all chemical signaling and statistics.

I travel in such large amounts that I eventually interact with the right systems.

It’s not really conscious when I change direction, it’s just kinda natural. I end up being like “whoa that was a big change.”

Something along the lines of how cells alone can have a goal but within a group exhibit different goals. This can go from cell to tissue to organ, all the way up to society. I’m not a biologist so I’m butchering his ideas, just writing this if anyone finds it interesting to look him up.

Right cells of a single individual co-operate, why should sperm-cells be any different.
Re:What You Don't Know About Sperm by chiefalchemist on Saturday January 06, 2024 @05:15AM (#38890160)
Yes and no. What's different about sperm-cells is you would expect an "every man for himself" behavior. Instead, they recognize (?) there might be other competition, other sperm donors if you will, and they therefore co-operate so one of their own wins.

Does this mean monogamy is unnatural? Or at least at one point was not the norm? And still isn't? As why continue to optimize for co-operation?

Re:What You Don't Know About Sperm by DougEiffel on Saturday January 06, 2024 @06:21AM (#38890486)
One hypothesis is that the shape of the glans penis serves to push rival sperm out of the way and behind the glans to be scooped out of the vagina.

I wouldn't call monogamy unnatural. But it may be a more recent invention for humans. We still aren't sure how long it's been the norm.

It's possible that humans used to rape more often. It's also possible that humans practiced forms of polygamy. Either way, cooperative sperm makes sense. It's one of those things where a simple mutation would provide a clear benefit over the competition.

You could expect that if each of them were an individual. Are they? One could say that all sperm-cells in a single ejaculation are part of the same single man.

Therefore the principle still holds, but it could be re-phrased as:

"Every sperm-cell for the donor-man"

All the other cells have the same DNA[1], they are like identical twins. It's like an army of clones.

Each sperm has a different DNA, they are like siblings. It's expected some cooperatio, but also some treason and backstabing.

[1] Ignoring some interesting cases.

> It's expected some cooperatio, but also some treason and backstabing.

That wouldn't be surprising, but I don't know if that is true.

I wouldn't not be surprised either way. A species survives not because its individuals do but because its genes do. Taking all available genes and spreading a subset of them amongst sperm-cells randomly is an interesting strategy.

It might be even optimal because the traits of a sperm-cell that make it survive during conception are not the same traits that help an individual thrive outside the womb.

If the 'fastest swimming' sperm-cell would always win, it would mean that in future generations faster and faster sperm-cells would win, but that would not necessarily help the survival of the species.

That seems to be obviously true to me. The alternative would be that consciousness simply appears at some point out of literally nowhere because there would be no lower levels from which it emerges.

Re:What You Don't Know About Sperm by eternauta3k on Saturday January 06, 2024 @05:39AM (#38890276)
Sounds like this

* pushes the problem one level down ("why are cells conscious?")

* adds the problem of explaining how consciousness of a person relates to consciousness of its cells.

What would this model help explain?

Re:What You Don't Know About Sperm by brabel on Saturday January 06, 2024 @06:05AM (#38890402)
Right, but it seems that both problems are easier than "it just emerges out of nothing".

Cells consciousness would be a much, much simpler sort of consciousness, something any "object" that somehow is capable of searching for food and avoiding "danger" should possess.

Higher level things emerging from similar, but lower level things is not a mystery, it's something expected (like ant colonies).

I'm vaguely for pan-psychism as in, it sounds good but I haven't thought about it for even 5 minutes. But I'm more interested in the version where all matter has some kind of proto-consciousness. Still, no idea how it's suposed to work in detail: how can it make a difference whether a particle is part of an information-processing system? There is an infinitude of mappings between physical systems and mathematical functions (I'm probably plagiarizing a half-forgotten version of this https://joe-antognini.github.io/ml/consciousness )
