Is it possible to selectively breed for intelligence Posted on March 10, 2023 by Anonymous Is it possible to selectively breed for intelligence
Damn, I'm surprised the AI was even allowed to answer this question.
erin hecht, Significant neuroanatomical variation among domestic dog breeds
Any image of those pug abominations brain?
A short article about it from 1887:
>implying more neurons = smarter
Cortex neurons (not general neurons) has a far closer correlation to observable intelligence than brain size and brain/body ratio.
>this is what encephalization quotards believe
If there's consistently the same intelligence test, I wonder if over time the animals barely get smarter yet get good at a specific set of tasks
Fun fact, a baby have more neurons than an adult human. This poop machine have more neurons than (you)
>Every day brings you closer to death
What a revelation.
Sure, once you find the smart-gene.
Sure, just need to define it and find a way to objectively track it first. Then its easy peasy from there.
Alright, I'll come up with an intelligent test for dogs (the difficult part), and you'll do the rest (the easy peasy part)
NTA but there are a good number of ways to measure for intelligence in humans that can be applied to mammals. Memory recall, color perception, reflex speed, etc. all correlate with 'g' or general intelligence factor. https://en.wikipedia.org/wiki/G_factor_(psychometrics) -- the idea being that intelligence is a reflection of an exceptionally performant brain. I'd argue the hard part isn't the tests or measuring, it's the keeping of animals and breeding them. All of that requires a steady income of cash and trained hands to administer the tests and monitor the subjects. Something simple like a small, rapidly breeding animal(like a guppy or some kind of solitary arthropod) could be done by some hobbyist who knows what he's doing, but anything bigger than that is going to require more and more resources.
Clearly rats are the right choice of animal. It makes me wonder whether it has been tried already.
No and any claims that there was are lies. There is no lab rodent trying to take over the world.
No, this does not correlate with general intelligence. This is a matter of physical ability.
neither does this... those nerve fibers are nowhere near the thinking part of the CNS.
This is g loaded but not as essential as people think. Intelligence can surprise you in that way.
We know for sure what is a reliable proxy for g in our own species because we are self studying from birth. With animals it is difficult, but also rather pointless.
>No, this does not correlate with general intelligence. This is a matter of physical ability.
You seem to be mistaking sensory discrimination for color blindness, or am I wrong in assuming that's what you meant? Sensory discrimination does correlate with g, even if not strongly.
>neither does this...
But reaction times do correlate with g. I'll admit I should've said reaction times instead of reflex speed but I hope you're not being pedantic about this.
>With animals it is difficult, but also rather pointless.
I mean the point given in this thread is to breed for intelligence so being able to measure a general factor for it has a point here. I don't know why you'd assume it's pointless outside of even that context though.
>we don't already have the means to determine that poodles are smarter than smashed and slammed micro exotixxx
they are smart dogs
Heres a thought experiment, lets assume some smashed and slammed mutt had some gigabrain up its slammed skull. Given that the owners are retards and its body is all fucked up, would the dog even be able to show it? Or others notice it?
>I'd argue the hard part isn't the tests or measuring
>requires [...] trained hands to administer the tests
So it is the tests in part too as you say. Specially since in this theoretical scenario they'd need to be done on every animal sample of a generation, correctly each time. With a constant track to make sure things aint going wack.
Also gonna have to ensure that diferences in g(if any) are factually result of genes and not nurture.
Looking at a another recent selective breeding as a baseline
It takes at minimum about 130 individuals and possibly around 30 generations for a concrete result wherein newborns are factually diferent from the beginning sample. About 45 thousand individuals bred. That however is just for a simple "friendly to humans" breeding, intelligence could likely take far longer. Doing the test you suggested for all of those animals, and doing it correctly would in itself be a massive undertaking.
Training, responding to commands. Shell games, picking the hand with more treats. Basic cause and effect: Schopenhauer wrote about his poodle understanding that the drawstring opened the curtains. Like with wh*te women, you just know.
>Training and responding to commands
This one has been proven to be bullshit when it turned out belgian malinois, who score lower the collies and labs in obedience, actually have higher general intelligence.
So the coefficient isn't 1.0, I'm sure the correlation is still strong
That's all quite fair but I would put forward that certain measures wouldn't need to be tested too frequently. You can also automate quite a bit for these tests since we're not aiming for that friendly nature to humans(which will of course require a human present for each individual). I'm reminded of the memory tests done with chimpanzees before. Essentially a game with a reward at the end. Transport of the animal and initial training to understand that game are important and then from there you have a standardized and computerized measure of their abilities(at least insofar as their performance with that game and all of the forms of intelligence/neurological ability it correlates with). I'd say that other kinds of games could be had too, like tests that reward delaying gratification, maze tests for spatial intelligence and memory, "quizes" where a subject is made aware of something at some point before the test and is then given a task to use information from that "something". An example of that quiz thing being to match the right color to an image of a car that they were shown a week prior. A lot of these tests though would be more fit for something as intelligent as a chimpanzee or a dog but tests like the maze test and basic tests to see if an animal recognizes patterns(An example being that I remembered was researchers putting a specific card against a guppy's tank before feeding. The more intelligent guppies associated the right card more often with being fed and came to their feeding area when the card was placed whilst the less intelligent guppies were more error prone).
Forgot to link a video of the chimpanzee stuff. https://www.youtube.com/watch?v=qyJomdyjyvM
I was thinking the same thing but couldn't put it into words. I'd like to add that flawed testing wouldn't undermine the entire thing, it's just gonna slow it down.
NO YOU CAN'T ASK THAT QUESTION, IT'S ILLEGAL!!!
That chart shows we're able to make them dumber, but can we make them smarter?
Marginally. It's far easier to topple a tower than build one. Relying on chance for incremental improvements takes a long time, but genes that aren't under selection pressure can be lost in a couple of generations.
They've gone 10,000 years with only moderate intelligence needed to reproduce, so I doubt we'll be seeing wolf-tier intelligence any time soon.
How does it show we can make them dumber or smarter? Without knowing what the neuron count of the original population of grey wolves dogs descend from, it's impossible to say whether humans have bred dogs to be dumber or smarter.
It's pretty evident that wolves are smarter, no matter how hard dogfags cope.
Even without testing them, it's still reasonable to assume that 10,000 years without selective pressures for intelligence would have an effect.
I'm looking for a neuron count like what the first commenter posted.
I've been waiting for to too, but all the seem to add are more dog breeds that no one cares about.
The only thing we cope with is not being allowed to have wolfwi…pet wolves.
I don't think it's a coincidence that the most wolf-like dog on the list also has the most neurons.
The "most wolf like" dog is still just as distantly related to wolves as every other dog.
No, the smarter dogs are just working breeds. Unless you think a beagle is more wolf-like than a golden retriever.
>cats with the least neurons on the chart
>still such adaptable and flexible hunters that they're completely holocausting birds wherever they show up
How do they do it?
Wasn't that bird species they 'holocausted' an island adapted species with no natural predators on said island? It isn't really impressive if the thing you're killing off is indifferent to your presence until you pounce on it.
Brain size is related with body size. A whale or elephant brain is much bigger than the human brain. But that doesn’t make whales and elephants more intelligent than humans
That's not what the image was measuring you dumb baboon-cat-moron.
more like tardoset
I keep wondering what gorillas think about. They're the dumbest great apes but have a high neuron count. Is it just fluff or are they hiding something?
A gorilla weight 4 times more than a chimp, this is why they have more neurons as the other anon was explaining.
How does that work? Do they process more sensory information? Do they have more neurons simply because their size allows it, yet they are wired less efficiently?
The gorilla's neurons are estimated, to there's a good chance that it's wrong.
Bigger animals need bigger brains to handle their bigger bodies both on physical and sensorial level. It happens that Gorillas are relatively smart for an animal of its size so things get weird. There probably is a minimum amount of brain cells needed as well for a complex animal so really tiny animals like tiny ants have surprisingly large brain to body ratios.
Isn't controlling the body almost entirely done with the cerebrum and cerebellum?
>A gorilla weight 4 times more than a chimp, this is why they have more neurons as the other anon was explaining
I don't think it's that simple for cortex neurons.
It involves both, body weight and intelligence. Just having more neurons don't makes an animal more intelligent but a small animal with same amount of neurons than a big animal probably is much more intelligent than the big animal. according to that pic
the chimp have 2/3 of the number of cortex neurons of a gorilla but it is 1/4 of its size making the chimp the one more likely to be smarter.
Cortex neurons really doesn't scale that much with body size.
>a small animal with same amount of neurons than a big animal probably is much more intelligent than the big animal.
Is that so.
I believe it.
Yeah? Are lions known to be particularly intelligent? I never heard anyone claiming that before.
Cats in general aren't known for their intelligence.
How bad are wild cats?
Not on the list.
I just want them to do to collies and huskies to compare with the shepherd. The consequences and shitposting will never be the same.
Dogs are an interesting case. Their number of neurons don't vary wildly despite their wild size differences. Since we artificially breed into extremes chances are that their brain and intelligence corresponds more to what would be expected from a wold sized animal than an animal of the same size
*wolf sized animal
If you look at the dogs here
you'll notice something. The neurons don't correlate that well with size, but all the smarter dogs are working breeds.
Those have to do shit instead of being purse accessories.
So you are saying the gorilla is much more intelligent than the chimpanzee because it have more neurons? Same thing applies, the chimpanzee is more intelligent than the gorilla despite having less neurons.
Gorillas are probably placed higher than they should be.
By having motor skills and not being inbred gnomes, while in most cases still being supported by humans.
The relation also is not linear with tiny animals having a higher brain to body rate so a mouse have a bigger rate than an elephant but the elephant is considered more intelligent.
They aren't holocausting birds. They have a moderate impact on birds. Humans are holocausting birds by destroying their habitats, introducing animals that prey on their eggs (rats) that nothing we want roaming free preys on (because canids also hunt livestock), and disrupting their natural lifestyle, and then the last few confused, unhealthy birds are promptly mopped up by the billions of cats. The cats weren't really necessary here, they just sped up the process slightly.
Nature: Scores 49 points
Dogs and foxes: On the bench for fouls (more like eating fowl)
Humans and rats: Scores 50 points
Cats: score an additional point for team human
Humans: wow cats just won us the game!
>More sociable and co-operative

based rodents. a snake will easily eat a thousand in a lifetime
Golden retrievers are the african americans of dogs
That would be pits. Would be interesting to see where they place though.
