Yes, until you describe the hows, you have these objections:
How did the Sahara desert in Africa made the Tuareg so much different than their corresponding Cowboys in the Mojave desert?
Or how did the wide snow planes around Moscow and Warsaw produce different mentalities than those of the Finish and Swedes?
Or how did the Aokigahara forest produce Japanese who manufactured TV and playstations while the Amazons produced various latino tribes who are still chasing monkeys with curare?
Here is another potential objection:
How did the Lands of the American continent produce today's most powerful empire while the native Americans did not even invent the wheel ?
Why did they not invent the wheel in the first place ?
