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 genes—>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 don’t get that completely random reshuffling of two parent’s traits. Some of them tend to stay “stuck” together.
This is called linkage, and it’s 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 *can’t* 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 can’t 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 general— that is, retention of childhood traits into adulthood. That’s 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 ‘domesticated’ themselves:
After an hour of planning and discussion, after 10 in game minutes to allow one of the player to take off their armor, after they rolled stealth checks and the lowest was an 18 (pass without trace), after discussing strategy and surprise attack order, just when the party was about to ambush the ghouls that had a wrecked ship survivors as hostages.
Me: The captain still screams for help, not knowing where you at
Cleric: Don’t worry we will come to save you (And we all knew she was rping because of the accent change)
Me: welp, let’s roll initiative
Anyone still unsure of how (or even whether) they’ll vote in the midterms should consider this: All three branches of government are now under the control of one party, and that party is under the control of Donald J. Trump.
With the addition of Kavanaugh, the Supreme Court is as firmly Republican as are the House and Senate.
Kavanaugh was revealed as a fierce partisan – not only as a legal advisor who helped Kenneth Starr prosecute Bill Clinton and almost certainly guided George W. Bush’s use of torture, but also a nominee who believed “leftists” and Clinton sympathizers were out to get him.
He joins four other Republican-appointed jurists, equally partisan. Thomas, Alito, and Roberts have never wavered from Republican orthodoxy. Neil Gorsuch, although without much track record on the Supreme Court to date, was a predictable conservative Republican vote on the Court of Appeals for the Tenth Circuit – which is why the Heritage Foundation pushed for him and Trump appointed him.
Even under normal circumstances, when all three branches are under the control of the same party we get a lopsided government that doesn’t respond to the values of a large portion of the electorate.
But these are not normal circumstances. Donald Trump is President.
Need I remind you? Trump is a demagogue who doesn’t give a fig for democracy – who continuously and viciously attacks the free press, Democrats, immigrants, Muslims, black athletes exercising First Amendment rights, women claiming sexual harassment, anyone who criticizes or counters him; who treats the executive branch, including the Justice Department, like his own fiefdom, and brazenly profits off his office; who tells lies like other people breathe; and who might well have conspired with Vladimir Putin to swing the election his way.
Trump doesn’t even pretend to be the president of all the people. As he repeatedly makes clear in rallies and tweets, he is president of his “base.”
And his demagoguery is by now unconstrained in the White House. Having fired the few “adults” in his Cabinet, Trump is now on the loose (but for a few advisors who reportedly are trying to protect the nation from him).
All this would be bad enough even if the two other branches of government behaved as the framers of the Constitution expected, as checks and balances on a president. But they refuse to play this role when it comes to Trump.
House and Senate Republicans have morphed into Trump acolytes and toadies – intimidated, spineless, opportunistic. The few who have dared call him on his outrages aren’t running for reelection.
Some have distanced themselves from a few of his most incendiary tweets or racist rantings, but most are obedient lapdogs on everything else, including Trump’s reluctance to protect the integrity of our election system, his moves to prevent an investigation into Russian meddling, his trade wars, his attacks on NATO and the leaders of other democracies, his swooning over dictators, his cruelty toward asylum-seekers, and, in the Senate, his Supreme Court nominees.
Senate Majority Leader Mitch McConnell has emerged as Trump’s most shameless lackey who puts party above nation and Trump above party. The House leadership is no better. House intelligence chair Devin Nunes is Trump’s chief flunky and apologist, but there are many others.
Now that Kavanaugh is on the Supreme Court, you can forget about the Court constraining Trump, either.
Kavanaugh’s views of presidential power and executive privilege are so expansive he’d likely allow Trump to fire Mueller, shield himself from criminal prosecution, and even pardon himself. Kavanaugh’s Republican brethren on the Court would probably go along.
So how are the constitutional imperative of checks and balances to be salvaged, especially when they’re so urgently needed?
The only remedy is for voters to flip the House or Senate, or ideally both, on November 6th.
The likelihood of this happening is higher now with Kavanaugh on the Court and Trump so manifestly unchecked. Unless, that is, voters have become so demoralized and disillusioned they just give up.
If cynicism wins the day, Trump and those who would delight in the demise of American democracy (including, not incidentally, Putin) will get everything they want. They will have broken America.
For the sake of the values we hold dear – and of the institutions of our democracy that our forbearers relied on and our descendants will need – this cannot be allowed.
It is now time to place a firm check on this most unbalanced of presidents, and vote accordingly.
This is so important. I am not American but as somebody who has studied politics and as a German growing up with the history of my country let me tell you – never take democracy for granted, you gave to fight for it. Democracies don’t always die with a big bang bloody revolution, more often they are slowly sabotaged by people in power and they die if the majority stays silent. Vote. Demonstrate.
This means you vote the Democratic party ticket, for the record. The time to shift the party to the left is during the primaries. Right now? You vote the goddamned ticket. Even if that means voting for Manchin, or some equally despicable Democrat.
Because let’s be very, very clear about this: if Manchin isn’t re-elected, it’ll be Patrick Morrisey in that seat: a Republican, who will vote the Republican party line on basically every fucking issue (because Republicans tend to have better party discipline than Democrats, at least at the Federal level), and a Republican who helps keep committee control in the hands of the Republicans and procedural control in the hands of the Republicans, instead of a Democrat who helps shift both those things into the hands of a group of people who actually want to block Trump’s agenda. By all means, vote Manchin out—but we cannot afford for you to do it right now. Do it in the primaries in 2024. Right now? You show up to vote, and you vote the goddamned ticket.
Yes, political parties suck. Yes, they force you, frequently, to gather with people who don’t believe 100% the same things as you. Suck it the fuck up. Sometimes compromise is necessary in adult life! That’s just how it works! This isn’t about one Democrat. It’s not about your Democrat at all. It’s about blocking the Republicans. And the only way to do that effectively at this point in time is to vote the Democratic ticket. Top. To. Bottom.
Reblogging for the @greywash comment especially. Vote like a grownup.
Thank you for saying this! Yes, it has to be democrats! Third party cannot win this one guys!
Context: So, for my first time ever, me and my group got a bit ambitious and did home-brew tabletop using 5e rules and some of their systems (also took inspiration from some of their classes.) we custom built races, classes, and gods based around a popular internet anime series called RWBY. Each class had VERY distinct purposes, advantages, and disadvantages, and the races were pretty much all advantage bonuses, with alignment disadvantages. One particular race specialized in Acrobatics and Athletics, the Faunus Primate, basically a human with traits of various primates, in this case, a strong monkey tail useful for grasping, climbing, and, in one instance as a sex toy. The group has been charged with saving a town from an infestation of monsters coming from a nearby cave system. At the entrance they are attacked, the Primate directly in front of the group, the other two behind them. The following ensued over the course of the game.
Ganjie: Ninja Primate faunus (sneaky acrobat (also a very new player to the game)
Hana: Duster Human (makes armor and weapons out of elemental infused dust.)
Dufus R Pointy-Stick: Warrior Animal faunus (has a pair of cat ears to enhance hearing and can see in the dark.)
Me: so, you all are ambushed by three beings vaguely resembling werewolves. Roll initiative with disadvantage.
Ganjie (OOC): …..i got a 4.
Hana(ooc): Two nat twenties, can I give him one?
Me: no.
DRPS (ooc): Alright, well, 13
Me (checking rolls against the werewolves): Alright the wolves seamed to move sluggishly, giving most of the group plenty of time to react, however, they emerged within striking distance of Ganjie, and are standing in front of him, what do you do, Hana?
Hana: wait, I have an idea! If I swing my halberd at them, can ganjie do a super epic dodge out of the way? Like, back flip over the blade or something?
Me: no… actually you know what go ahead, it sounds cool, both of you roll, but hana you have to roll to hit both the lead wolf and ganjie since he’s in front of you.
They roll.
Hana: um, 16 on the wolf and 13 on ganjie
Ganjie:….. um, 7 after the plus 5 modifier.
Me, laughing: alright, Ganjie, you manage to feel the swing coming despite Hana giving no warning, and successfully jump in the air. Hana hits your leg with the halberd’s haft. Take 1d4 damage, and roll with athletics to see if you can recover when you hit the ground.
Rolls
Ganjie, looking extremely dejected now: nat 1.
Me, trying to contain my laughter: the hit was strong enough to set you off course. You complete your back-flip, but can’t stop your rotation and end up falling face first into the muddy ground. you’re now prone for the round, covered in mud, and have taken friendly damage.
DRPS: so…. he’s not in front of us anymore right?
Hana: is face palming while yelling “I’m sorry” a free action?
