>>14380772What the fuck are you on about!? They don't. Parasite Stress Theory is bullshit. You're making the assumption that the cold winters force societies in colder climates to plan ahead. That doesn't mean the brain is 'performing better', because hunter-gatherers are way better than you at hunting and gathering. Their brains out perform yours in that task.
Brain performance on the individual level is substantially different from complex and sophisticated culture. Especially since the more that you axiomatize and create heuristics, the less brain power is actually required to perform tasks.
Your brain isn't performing better because you have a calculator than someone who has to do it by hand or in their head.
