A convincing argument against polygenesis, the idea that humans evolved independently in different parts of the world, is that people everywhere can interbreed.The argument states that it would be highly unlikely for this property to emerge spontaneously in different populations.My question is: Doesn't lose this argument its persuasive power now that we've discovered Neanderthals interbred with Homo sapiens women?
>>16738116they were too K on the r/K evolutionary model scale, they consumed too much energy per individual and were unable to adapt to a more harvesting lifestyle after the end of the glacial air like homo sapiens, their weak point would perhaps have been to be too intelligent to the point of ask too many resources per individual which meant that they were overwhelmed by the homo sapiens who multiplied
>>16738116>why'd they go extinct>comment chain starts with "they aren't extinct"You'd have to be able to differentiate between country populations within Europe to spot it, I suppose.
>>16739356>To imagine that a species could gain 20% of cranial volume in 10,000 years is indeed ridiculousWhy? Modern Europeans have lost nearly as much since then

Is there any scientific truth to this racist ass meme I just came across?
>>16726652It's smiling!
>>16738280Shouldn't say the n word mothafucka. @grok is this true?The picture most likely goes in reverse and stops at the ends of the extreme. Cooked food made you smarter.
>>16720276>IQ is a racist, colonialist myth >we must shut down the lead paint factory because the kids living next to it score 4 points lower on IQ tests
>>16719852>no, everything in life except IQ is genetic>>16724219>Unironically true. IQ is largely a function of childhood nutrition and random factors like how often you caught a cold in your childhood, the air quality in your room, whether you slept with a blanket over your head, maternal vitamin D levels, your vitamin levels etc.Intelligence is affected by genes, but not as much as people think. There's a lot of variance.Im significantly smarter than all my family members. One of my siblings is probably around 105-110 IQ. I'm around 145-150.
>>16719801Yes, it's called averages.
What is the ratio of one of the small circle to the big circle encircling them all?
>radius of small circle:>1 petal>radius of big circle:>3 petals3:1. That's the ratio.
>>16740385Is it 3:1 or 1:3?
>>16740386Big:small is 3:1Small:big is 1:3
>>16740387Does the order matter in ratios? I seems like it does when you convert it to a fraction or decimal.
>>16740389Depends on the application. Which one should come first is based on what you're trying to do with said ratio.
Did AI get this right when asked to create what calendar would be 450M years ago?>Year: 400 days, each about 21 hours long.>Seasons: Four, each exactly 100 days—division is mathematically perfect and astronomically anchored.>This period coincided with the Great Ordovician Biodiversification Event (GOBE)—the largest evolutionary leap in Earth’s history—suggesting the environment was fine-tuned for supporting the explosion of life.
Scientifically speaking how come this happens? I thought being near a magnetic field is safe for humans.
>>16740248Time to go bedbunk diving friendo
>>16740230There's gonna be more pollution in areas with more power lines.
it's non-ionizing radiation but just because our ions are safe, does that mean it has no effect on us?is it not possible the em waves induce small amounts of current in our body?high power transmitters need to be shutdown to work on, or technicians have special suits, because at the source the waves literally cook you and you dietrees near those kind of transmitters dieyou're only getting a bit of those waves so should be ok, a bit of those waves every second of your life
>>16740249Yes it is. Always.Just because your tiny mind can't fathom why cheese and bedsheets are related doesn't mean they aren't.
>>16740230The magnitude of the electromagnetic fields decays as the square of the distance from the power lines so someone living 50m from the power lines would be exposed to 144x the radiation of someone at 600m and you would reasonably expect a vast difference in leukemia rates between these distances. Since this uncited article hasn't said that presumably they didn't find this difference and it doesn't exist. The most likely explanation is >>16740281This is the same thing as the 5G conspiracists.

>>16740283There is a good chance your actual workflow will mostly be using dependencies and APIs written by someone else, so again you're probably looking more at reading and understanding documentation than advanced math. Most modern coding is basically just stitching together different dependencies. Python is particularly notorious for this for example. That language is almost just a wrapper for gluing dependencies written in C together. If you are playing with C directly, there is still a good chance you will primarily be using libraries written by other people and will not actually need advanced math. Programming is way easier than most people imagine.
Can someone give me an intuitive explanation of why the power rule in integration/differentiation works?These are obvious: >f(x)=x when f'(x)=1>f(x)=(x^2)/2 when f'(x)=xI brute forced this one as a limit of a harmonic sum:>f(x)=(x^3)/3 when f'(x)=x^2But is there some retard simple way to prove the generalization?:>f(x)=(x^(n+1))/(n+1) when f'(x)=x^n
>>16740285Thanks, anon. I'll continue to work on my math, but I'll focus more on my practical skills then.
Why can't we eat meat raw if we evolved to eat meat
>>16740372Raw meat is fine. It's whatever it may be contaminated with that might cause issues. If the animal was healthy before butchering and the meat was handled in a sanitary way then there's nothing wrong with eating it.
What will the first really big AI controversy be? I think soon there's going to be a very important photo or video thats going to be world wide news and that photo/video is going to be exposed as AI and its going to cause people socially to question the validity of everything.
>>16739865I think its going to be something very egregious like a hostage photo or something blackmail based
>>16739637half of the point of quality journalism is putting your name on the line over and over again in relation to the stories you publish to build trustit is not in the interest of an actual journalist to publish nonsense because that shreds their credibilityof course, lies and misinformation gets half way around the world before the truth gets its pants on, and there is massive incentive for "journalists" to publish clickbait to drive eyeballs to the ads that sit next to their "stories"and, of course, the general public has shown both a complete disdain for paying for quality journalism and a complete lack of ability to differentiate truth from falsehood, so here we are, with people getting their "news" from social media and being overall fucking idiots.the post-truth society fostered by the internet highlights humanity's achilles heel
NEETs win againnobody cares so nobody bothers the NEET shall inherit the earth
>>16739924An accurate assessment.What we are seeing is the accelerated polarization of information. Just lagging some decades behind the polarization of wealth.An increasingly greater proportion of the population will become disenfranchised not only from economic mobility but also from quality journalism.In this case it will be a small number of well informed Morlocks inhabiting the Earth's surface while the far more numerous and ignorant Eloi live underground.
>>16739637It's still insane what they're working on is literally the last thing we need. Creating fake videos for deception. Good job fucking piece of shit retards.
Is there any reason we can't just kill all the mosquitoes? Would it really be so bad? Would it really be the end of the world? Would it even have any negative impacts on human society? I don't really care about a bajillion species I've never heard of go extinct.
>>16740255They're incidental pollinators, at best. Nature would adapt.Sure, some arctic bird species would also die out. But honestly fuck em.
>>16740287all pollinators are incidental retard it's why wasps, hornets and ants are important to the life cycles of flowering plants
>>16740246they are a bottom level of several animal's food chains

why is so hard for scientists acknowledge their mistakes?
>>16740354Anon, I know you're excited to finally be starting college in September, but seriously, wait until you're at least out of your first year until you try to have arguments you're not ready forYou might have been top of your debate club at your high school in Podunk, Indiana, but that doesn't mean you actually know what you're talking about
>>16740347>They aren't closely related: Science is an extension of philosophyAn extension is a close relationship. Can you do anything other than nitpick on terminology you fucking schizo?>Physicists talk about consciousness all the timeIn a descriptive sense. It is genuinely a mystery what consciousness is and how it operates. That is scientific and not relevant to questions about meaning or whatever.>>16740347>I asked, repeatedly (with still no answer) what Standard Model of even over the counter physics has accomplished in 80 yearsGoing through your posts, you were given answers. You just pull ways to disregard them out of your ass because you don't care about truth. You care about "winning."

>>16740208>neutrino tomographyfucking kek
>>16740208Well what i mean is why do we only send probes or get images from one direction in space? I want to know what's below all of this.
>>16740314Hell
>>16740210Use your words like a big boy--I know you have it in you.>>16740314The answer is still neutrino tomography. The reason "we only send probes" is because the current standard model is shit and midwits refuse to leave the Cult of Einstein for greener pastures.
>>16740198Also with the lunar rovers they sent to the Moon, they could've just send them to the site of the Apollo landing and took pictures of it, but they never did
Maybe the reason why Europe is so much steps behind usa in science consists of the fact that europeans don't let asian migrants do the science? Usa cares only about efficiency and let asians do all the hard part while old white men could claim achievements of asians in collaborative work. So white people can larp both as superior and also delegate all the hard work to asians to make the academic system work. Europe should learn from America to invent something more useful than attached bottle caps.
>>16738177There aren't 350 million native americans, there are 1 billion americans in the north and south america
The USA brain drains a lot of the best scientists, but Europe is still competitive in most non-meme fields. The USA of course is ahead in stuff like "AI".

if the world is quantum, and space only advances in planck scale increments, then how does the concept of derivative make sense? >take an infinitely small distance dx....NO, YOU CAN'T DO THAT!!!! space doesn't work like that.most maths is built on a false premise, it needs to be completely outphased
>>16740329Learn what a derivative is, and then come back.
It works because it's a good-enough approximation. You don't need to model the universe with 100% accuracy to make good predictions.
>if [FALSE PREMISE] why [ILLOGICAL CONCLUSION]Why do i even bother with this board
>>16740329>mathsmath*
>>16740329>and space only advances in planck scale incrementsThis is a pubsci meme that few physicists are interested in, because it's untestable at our current level of technology. However, if such a fundamental lattice existed, it could use discreet derivatives that would approximate (to an extreme degree of precision) the continuous derivative at length scales well above the planck scale. The maths would be a bit messy since the lattice can't have the same symmetry as 3D space, but it would work.
