thor: so youāre saying that my secret older sister isĀ the goddess of death and that you locked her away and imprisoned her for who knows how long but now she is out and beyond powerful and will stop at nothing to conquer asgardā¦ā¦and you didnt think that it was important to ever mention her before????
odin:Ā ā¦ā¦ā¦ā¦ā¦.yes. due to personal reasons i will be passing away now.
thor:
lmao most discourse on this site is tainted anyways cus most of u guys dont seem to care about bettering urselves or about spreading good information and trying to encourage people to do better, u guys just like winning an argument and looking at things through a black and white mindset until u have enough to make a callout against someone
domestication syndrome is one of the coolest findings from recent genetics
Yes!
Basically scientists have found that if you start selecting for people-friendly animals, you see a bunch of hypothetically unrelated traits start showing up in all sorts of mammal species: floppy ears, piebald/patterned coats, etc.
This is true for everything from cows to dogs to rats! One of the coolest long term studies on this has been the Russian fox experiments.
So essentially the science goes like this:
You have two copies of every genes, one from each parent.
We tend to simplify genetics, and say that for every single gene you have it is random,l coin flip which copy you pass on to you offspring. We also tend think of genes as a 1:1 ratio of genesā>traits.
But! This is not quite the case.
Genes have a specific physical location and order relative to each other on your chromosomes, and the chance of genes being inherited together goes up the closer together they are located. This means random, unrelated traits can wind up being more commonly inherited together in specific patterns just because those genes are located close together, and you donāt get that completely random reshuffling of two parentās traits. Some of them tend to stay āstuckā together.
This is called linkage, and itās why you often see red hair, pale skin, and freckles together, for example.
The second factor that plays into this is that a lot of times 1 gene affects several different traits (or several different genes affect 1 trait). This means that sometimes you really *canāt* untangle two traits because they have a similar cause. For example, say genes for increased aggression are responsible both for making a spider a better hunter (pro) and making a spider more likely to eat its offspring (con). Because the same gene is the cause of both things, natural selection canāt really untangle them.
Circling back to the redhead/freckles/pale skin example, these traits are affected by a number of different genes, but also one gene in particular: MCR1, a gene that changes how your body responds to hormones promoting melanin production. Again, one gene related to pigment production can affect a BUNCH of different traits. (And also skin cancer risk. Fun!)
Domestication Syndrome in mammals turns out to be due to both linkage and genes affect by multiple traits!
See, when we domestic animals we want them to be friendlier/less aggressive, which normally translates to less FEARFUL.
And it turns out that the same genes involved in adrenal responses and other stress reactions are also involved in melanin, cartilage, and bone production. So when we domesticate animals we get these recurring changes in pigmentation (white patches, piebald costs), floppy ears (cartilage), shorter muzzles and other changes in physical stature (bone growth), etc.
We also wind up selecting for a lot of neotenic genes in generalā that is, retention of childhood traits into adulthood. Thatās because baby animals tend to have lots of friendly/trusting/biddable/curious traits we are looking for.
And honestly, who can say no to a face like this?
ps, since it was mentioned:
the same genes involved in domestication probably help animals form social groups in general. if you need to get along with and trust strangers you need a decrease in the panic/aggression genes.
cats, for example, probably domesticated themselves when they started living close to each other and to humans to feed off of pests in grain silos.
and yeah, some some recent theories suggest humans may have ādomesticatedā themselves:
so basically youāre saying that when we breed animals to be friends, they become friend-shaped.
I spent the afternoon arranging our books by size and color (and itās so satisfying and looks amazing) and my partner came home and stared in shock at the bookcase and then said āiām a librarian, you canāt do this.ā
him: you split up all the song of ice and fire books
me: yeah i know, theyāre all primary colors, itās perfect
him: [self-destructs]
Youāre a monster
As a former bookstore employee, this hurts my soul. I mean, sure it looks nice, but how do you find anything?
it has occurred me during this process that apparently not everyone thinks about books by what color they are? like, literally when iām looking for a book, i picture it in my mind. i have a veryā¦tactile experience with the books i read and idk! i thought everyone did that lol.
my partner was likeĀ āhow will i find [this book] for instanceā and i repliedĀ āeasy, itās purpleā and he looked at me like i was a witch.
OP your brain is neat and I love you for it you funky little color-coded cupcake. But youāre still a monster.
wow i love this
One of the truest things Iāve ever heard is that people who say theyāreĀ ābrutally honestā are more interested in the brutality than the honesty.
Me to men everywhere
š There are 3 things about this video that get me every time:
The āohmygaudā
The āoop!ā
And her face at the end š
Consent. You betta Lil Sis.
lizard out there really gonna do it
this lizard is braver than any US marine
heās going for it, the absolute madlad
ok but imagine peter not caring about his secret identity anymore and not making any effort to conceal it yet absolutely no one finds out heās spiderman. peter wears the suit under his pants and a jacket but literally no one notices. he only gets a ācool shirt dudeā from a student he doesnt know. he does the iconic spiderman shooting-webs-from-his-hands pose in every single picture. no one says a word. he enters the classroom through the window. just as him, not spiderman. the classroom is on the second floor. no one cares.
Sounds like college
āman that peter guy really likes spider man, i hope he gets to meet him somedayā
They make it sound like her profession is what caused her to be murdered. Smfh
So I posted this on Twitter:
And then when I refreshed the page:
and yes, I had to give them my phone number to get my account back.
āunusual behaviorā god i love the cybpunk dystopia
Can we as millennials and gen-zās collectively agree that NObody Cares about elbows on the table like Why was that Ever A Problem for Anyone?? We can chill right?
nobody asked for this but the origin of not putting oneās elbows on the table comes from the late 18th/early 19th century when wooden ships were still used in the navy- sailors would balance their plates between their elbows while eating to keep them from sliding around. because sailors developed a reputation on-land for being uncouth and aggressive, the placing of elbows on the table became associated with such behaviour.
some cultural historians believe it also goes back further, to the middle ages, when large banquet-style meals were served on trestle tables that had no side support. if someone put their elbows on the table, they risked bringing the whole table down with them.
so basically, there is no longer any need to NOT put elbows on the table, and there hasnāt been since the advent of steamships.
I love this because now i can smartass the next person who tries to give me shit for it
i didnt want to pay for a book so i just went to the library and took pics of every single page like all 300 pages do u know how many looks i got like 10 and the girl next to me was face timeing and trying not to laugh and i just like waved and she started choking
i hate when people misunderstand my shyness for unfriendliness like no!!! i actually like you! iām just a piece of shit that canāt communicate
abusers will say you have to be strong just so they could keep hurting you
