Credit for IQs above 80 is owed to the fierce competition with the Neanderthals. Killing them off was essentially an IQ test of increasing difficulty. No peace treaty was ever possible with them so it was kill or be killed. Africans did not participate in this 20,000 year war, which is reflected in modern genetics.
Man, how I would like to jump into a time machine and go back and watch it in person!
The Heavenly Father created all souls... and it is the devil that has spent the past 10,000 years plus, creating division amongst the races .. WHY? Because it ‘sells’, some just love to promote their high IQs... and solve nothing. Why the Netherthals population views themselves above the rest ... but are they really viewed that way in the sight of the Creator ... we will find out.
Neanderthals were assimilated not killed off in some fanciful war.
