In colder average temperatures, cognitive function is reduced. That's a direct evolutionary pressure that rewards adaptation for better brain function. Humans under cold weather selection pressures will select for traits that allow for efficient brain function in cold weather, and some populations will experience Fisherian runaway selection for those traits like the peacock and it's tail leading to high IQ populations like Whites and East Asians. Agricultural revolution is obviously not the source of higher intelligence because every major agricultural population is low average IQ save the populations who have large amounts of North Eurasian DNA - Saami nomads who've never practiced agriculture in their entire history average 101 IQ, pureblooded Sardinian farmers have some of the lowest IQ scores in Europe. Runaway selection also explains why some North Eurasian races are high IQ whilst others are not. There are analogues to this in the animal kingdom, like parrots needing to evolve anti-aging adaptations to handle the high metabolism required to efficiently digest nuts and seeds, and Fisherian runaway selection causing them to evolve lifespans significantly above other animals of equivalent bodyweight.
>>537787810the biggest cold weather adaptation is learning to survive the winter, which requires lots of thinking and planning
>>537787810What a useless piece of shit of a post
>>537788050People would also plan for rain in the desert, but desert populations don't have high IQs. The difference is in frequently cold climates your brain functions worse which is a direct environmental pressure to evolve better cognition. And since human cultures have different sexual selection criteria, certain cultures naturally selecting against cold weather cognitive reduction would experience Fisherian runaway selection.
>>537787810So why aren't Eskimos engineers and scientists?
why are euros all retarded then
>>537789963because OP is a fucking low IQ buffoon who doesn't understand basic selection bias about his retarded pet theory of being a moron
>>537787810in case you think you came up with some moronic theory i'm going to tell you i have lived in the cold and it doesn't reduce IQ. what happens is that after a while the body adapts to the climate exactly like when climbing a mountain and adapting to the lower oxygen level. being in a cold place doesn't mean anything about natural selection for intelligence all it does is make niggers into albinos so they don't die from vitamin d deficiency
>>537789963You didn't even read my post.
>>537787810>Body becomes hypothermic, a survival mechanism stressing all organs in the body. >this is healthy, so it more. Next 4chan tip: hang yourself for better breathing down the road! Have you considered the benefits of starvation?
>>537789963Because hunter gatherers/nomads don't have the excess resources to pour into specialization like Europeans did. But Eskimo's do indeed have the biggest brains out of any race, generally.The downside to agriculture is it reduces your brain sizes, so Euros had to go into specialization to sort of recoup their collective cognitive losses on an individual basis
>>537790111You literally didn't read my post. I explained that weak gotcha - Fisherian runaway selection results in some populations developing higher average IQ. Notice that even though Eskimos don't have high IQ averages, they're still significantly above the majority of South Eurasians in average IQ according to the Becker tests (91-99 average). That's higher than the averages for many long term agricultural civilisations in South Asia and the middle east. Actually, low Inuit average IQ has never been conclusively observed. Also note that all mongoloids descend from a Northeast Eurasian population that evolved under winter pressures.>i'm going to tell you i have lived in the cold and it doesn't reduce IQWe have data clearly demonstrating that low temperatures <16C reduce problem solving speed in healthy individuals. That is a selection pressure for higher intelligence, if your brain isn't working as well as it should in a cold weather climate, people who can operate normally will begin to be selected for, and in some cultures that selection process will keep going. We see this even in other animals, like marine mammals and Kea parrots
>>537787810>and some populations will experience Fisherian runaway selectionIt has nothing to do with mate selection. It has everything to do with higher survival rates and thus nothing with fisherian runaway selection. The death rate for stone age hunter males in northern europe was huge, not because of wars, but because it was very dangerous to hunt along the receding ice. Few males reached the age of 40. This is also why scandi males can work in flat organizations, which is unheard of elsewhere. That is the natural organization for a small hunter band of 12-20 people. Packs with good coordination simply survived at a higher rate. Because of the high death rate among males, this had a very high darwinistic selection pressure.
>>537791162higher metabolism doesn't mean better brain function you fucking moron. your theory doesn't account for any kind of mechanism that would select for better brain function that magically makes albino niggers smarter
>>537791262Multiple bullshit being spouted here1. Stone age hunter gatherers did not have short lives, they tended to live significantly longer than the malnourished agriculturalists who succeeded them.2. Scandinavians carry very little if any DNA from ancient stone age Scandinavian hunter gatherers, who died out. Their DNA overwhelmingly comes from Bronze Age Indo Europeans and Anatolian farmers who carried Hunter Gatherer DNA from different locations in Europe.>This is also why scandi males can work in flat organizations, which is unheard of elsewhere. That is the natural organization for a small hunter band of 12-20 people.Yeah, just total fucking nonsense and not true at all. Scandinavians can do that because North Eurasian populations evolved for higher IQ level and cooperation and Germanics have vasopressin and oxytocin genes linked to reciprocity. Those traits are not from "hunter gatherers" they are from Aryan horse lords who had large functional militaries and states.>Because of the high death rate among males, this had a very high darwinistic selection pressure.That's just bullshit. People are trying to always find some magic bottleneck that explains higher White and Asian intelligence when the obvious answer is just an evolutionary response to cold weather making the brain less powerful
>>537791596>your theory doesn't account for any kind of mechanism that would select for better brain function that magically makes albino niggers smarterYes it clearly does. >Cold weather makes it harder to solve problems than usual >Selection takes place for genes that address this>Evolution often overcorrects, the genes in some communities are over selected for>Now you have smart humansNot rocket science.
>>537791894there is no selection for brain function, you have no fucking clue what those words even mean. higher metabolism in cold weather is the only adaptation ever observed, that's it, there is no magic gene for "better" brain function you fucking retardmoreoever, i can take your retarded argument word for word and apply it to hot climates and it would have the same outcome, smarter niggers
>>537787810>Magic weather argument #5573Explain the Selknam and other southern pole tribes
>>537792038he doesn't have an explanation, he has a magical story for why albino niggers should be smarter because he's an albino nigger and wants to be smart but he's obviously retarded
>>537787810agreed. this is a big theory as to why whites are seemingly more intelligent than those who live around the equator. our bodies and brains had to adapt to the colder European climate, and thus made us better and smarter.
>>537792325ya, niggers and arabs had to do the same for their climate and that's why you are now all going extinct in your own countries you fucking retards
>It's da hecking geographical location and not the genes
>>537790111It's not a pet theory, its a solid well research hypothesis. You're not white.
>>537787810Living in cold climates is harsh and living in warm climate is living life on easy mode. Nothing new here.
>>537787810the cognitive penalty from cold air is negated by wearing something warm and lighting fires. harsh winters just require you to plan ahead, that alone is enough to explain intelligence differences
>>537792695you can tell from the screen you're staring at the color of my skin. this is why you are a fucking retard and why your people will be extinct by the end of the century because it's getting hotter and albino niggers can't think well in hot weather
>>537792570Ok and what do you think the surrounding environment does for genes of populations?
>>537789963>So why aren't Eskimos engineers and scientists?Visit any USA university and its full of east asians.
>>537793019do east asians live on cold or how climates?
>>537788050Also, cold weather leads to more reading indoor activity and less outdoor extroverted activity
>>537793401Yes. All the east asians you see in china descended from them.During the spring and autumn peroid, southern china was just a bunch of sun nigger tribes.
>>537787810How do you explain the high IQ of whites in warm climates? Lol. This brown cope is hilarious. Just stop. It's embarrassing.
>>537793911Whites come from colder climates and carry snownigger genes. Whites haven't lived in warm climates long enough to have adapted to living there (if they had they wouldn't be white).
>>537791711>1. Stone age hunter gatherers did not have short lives, they tended to live significantly longer than the malnourished agriculturalists who succeeded them.Yeah, stone age _women_ had long lives, stone age sub artic hunter males died early and often. That means that the strong and smart had a disproportionate amount of offspring because they survived to 37 fathering dozens of children while the shit talking thick skulled low brow proto-australian died in his second year as a junior hunter because he got cornered by a mammoth while trying to show off. Can you imagine how your shithole would look after 1000 years if 50% of the males were dead before 25 due to not being smart, strong and cooperative enough while population numbers are kept up due to women surviving much easier and longer? No you cant because you cant do hypotheticals. But I can tell you that it would have a huge positive impact on population fitness.
>>537791711>Yeah, just total fucking nonsense and not true at all. Scandinavians can do that because North Eurasian populations evolved for higher IQ level and cooperation and Germanics have vasopressin and oxytocin genes linked to reciprocity. Those traits are not from "hunter gatherers" they are from Aryan horse lords who had large functional militaries and states.These traits were selected for _before_ there were any aryan horse lords you dumbass abo. They were a necessary prerequisite for large scale organization, not the cause of it. Do you think these aryan horse lords just sprouted out of the ground? Have you ever looked at a map of Europe during the ice age peak?
