Some groups insist that "clocks are racist" because white people are always on the move, living by the clock, and using their time to get things done.
If you evolved in sub-Saharan Africa, or in an island paradise, food literally swims at your feet and falls off the trees onto your head. You don't have to work very hard to get it. You don't need a lot in the way of shelter, either; just something to keep the rain off and the animals out. For anything big like a major storm, head to the nearest cave for a while and you'll be fine.
It's actually counter productive to work hard messing with your environment when it's providing for you just fine as it is - not to mention working hard all day in a hot steamy climate. It works better to use patience, live more slowly, and let the food come to you. That is the concept of "island time" and it continues in those places today.
If you evolved in the Northern Hemisphere, you had to deal with cold and ice and snow and marked seasonal changes. You had to control your environment so it wouldn't kill you, and that meant far more work to get food and build shelter and keep warm. It would have been counter productive to live life in the slow lane, because you'd starve or freeze before the first year was over.
But this did lead to a drive to work hard and to an increased ability to invent things and find solutions to problems. That is the concept of the "work ethic" and explains a lot about why the civilized/"first" world is populated the way it is.
I'm convinced that this is the root cause of the screaming arguments, huge culture clash and "racism" between these two groups everywhere you look, and why neither group understands the other.
It's almost like separate cultures evolved for a reason and there is nothing good that comes from forcing them together.
Sounds cool. But Caucasians from the Caucasus and Aryans moved down into the hot lands, immediately spurring development of technology. Iran, land of the Aryans and all the Mesopotamian area, Egypt etc, were all ruled by Caucasians.
Alternate archaeologists discuss the plain evidence of the ancient copper mines in what is now the USA, and the ancient empire coins found there, drawing lines to the copper empire and noting that the middle eastern regions did not have sufficient copper to explain the trade and wealth that built the age of copper.
One may argue evolution, one may argue the tower of babel, but the key would be genetic versus social, nature versus nurture. Are all tropical people relegated to lack of inventiveness, low work ethic? Obviously not- I have met, hired and worked with a considerable amount of people from Central and South America, Africa, and the middle East. And I have run into all sorts of lazy from all corners of the earth. Black people were a lot more industrious in the USA before they were re-enslaved by the deep state. Haitians are industries as all get out. Hispanics, Brazilians, oh my gosh they are brilliant and hardworking too. Evolution cannot explain any of that.
I was talking about cultural evolution, not necessarily physical/mental evolution.
