You are mixing few different things here - yes AFAIK sherpas / tibetans have genes preselected to cope better with altitude, but there is absolutely 0 zilch nothing of such about 'crowded city or a submarine'.
WTF would that actually even be, submarines have cca surface pressure, maybe you meant adaptation to generally shitty soulless draining more stresful environments? Again, nothing like that out there in gene pool, city folks generally love running away to the nature as much as they can, at least those who already experienced how healing and recharging it can be and can afford it.
- JoeAltmaier 2y agoYet they screen successfully for submariners and get a good crew. Their genes came from somewhere. And every human in existence has been adapted over the last 50K years for tribal, village and city conditions. Early hominids were very different - hairier, loners, more fractious, used more calories, communicated less. AMH (anatomically modern humans) have co-evolved with crowded conditions, to live in groups and tolerate each other without killing one another. So maybe three modifiers on that was hyperbole.
- c420 2y ago>And every human in existence has been adapted over the last 50K years 50k years is a blink in the context of evolution. You're looking exclusively at cultural adaptations in this timeframe.
- JoeAltmaier 2y agoNot an evolutionary biologist? Read up on it. Humans have evolved more in the last 50K years than in the 1M preceeding that. I'm talking about biological adaptation, though you bring up a reasonable point that cultural adaptation is another tool to help bring success.
- jajko 2y agoMan you are all over the place and mixing stuff that doesn't make sense. Evolution of some trait as adaptation to environment vs selecting by test from general population with variable levels of traits are completely different things. The other points are in same vein, no point wasting more time.
