  • we have hair all over our bodies. most of it is vellous hair though so it isnt as visible. we just have far less terminal hair than other primates, but the hair density isnt that much lower. as far as the head hair growing long, its not that its unnecessary its just for different purposes than most animal fur. head hair is primarily social, and people like people with long hair, so theres a social benefit to having nice head hair that can grow long. its so ingrained that being completely bald is socially isolating to some extent, especially for women.

    this feels like one of those shrink wrapped dinosaur situations. like they arent doing a good job estimating how her soft tissue would have been distributed at all. why are her eyebrows so low, why are her cheeks so lean, why is there so much tissue below her lips, why is her hairline so high and with a bit of a widows peak? it feels like they put a mans tissue distribution on a womans frame completely uncritically and called it good.

    edit: i think the harsh drop lighting theyre displaying this under is making it way worse too. it might not look quite as bad with softer more diffuse lighting.










  • because it was never vital to survival to have fewer bones. evolution is a term that does a ton of conceptual heavy lifting but has sadly been warped by ignorance and a lack of understanding of the nuance of what is really happening.

    somehow, life existed. we dont really know how it got started but it did. due to the laws of physics and thermodynamics, some life died and some life lived. that went on for a long ass time until today we see the stuff that has survived to now. evolution just says life changes over time because some life dies without reproducing and some life reproduces before dieing. thats it. its a statement about the effect of survivorship bias over the long term existence of life.

    so why didnt animals evolve to have fewer bones? because it never mattered enough to happen. things kept on surviving with the number of bones they have. we can look at them and say their body would function better with more or fewer bones, or different chemistry, or different soft tissue, or whatever you like. but none of those things mattered enough to happen, or if they did happen they werent better enough to change anything at the time. but also animals do have different numbers of bones, just not so different.

    i wish i could describe this better, but evolution isnt an active process. if you have to think of it as a thing, keep in mind that it produces only what barely works. every adaptation we have was developed by the deaths of countless individuals, so we only have it because at some point it was necessary, or so benefitial it couldn’t help but propagate. having way less bones was never either of those things.



  • there is a distinct you, its all the cells with your dna, and theres no bacteria inside your body. your stomach and intestines are functionally a well controlled part of the outside of your body. bacteria being inside you is an infection and is generally considered bad for your health. by mass the vast majority of your body is your own cells, so implying most of your body is stuff thats “not you” is pretty hyperbolic.

    your argument that it would probably be bad to kill these mites is an appeal to nature. just because theyre there doesnt mean they serve a vital function. im sure there are any number of disorders caused by them, but whether there are any caused by them being absent neither of us can say. maybe there is, maybe there isnt. its possible that no one can say at the moment.




  • totally. my latest ex is pretty socialist and anticapitalist, and i agreed with them on pretty much everything they said, but they drank the coolaid on using classical communist jargon to talk about stuff. half the time they would use definitions for words that were, to be generous, at odds with commonly accepted definitions. then they would get pissy and the discussion would devolve into semantics because they would only accept those definitions, while i was trying to use the normal definitions because of fucking course i would. so would almost everyone else. so in order to talk to them about government or politics without causing some kind of misunderstanding i would have to read a bunch of communist literature from the 1800s. i confronted them with the fact that this is a problem for the movement in general and they should be more straight forward with their words, but they just got pissy again.

    it really sucks as a situation because theyre right, they just cant fathom that you cant expect people to read a bunch of old ass books in order to understand wtf theyre saying. add to that the jargon has been coopted and memed to death so every conservative gets triggered like a sleeper agent hearing the code word to execute their mission, we should probably abandon it and just talk in simple practical terms people can understand.
