No argument about all of us humanoids having a common, African origin. However, the different rates of evolution and adaptation of migrating tribes cannot be denied.
And it continues today. If you live next to bunch of noisy, rude, uncivilized, paid-on-Friday broke-on-Saturday, drunk or drugged, trashy, irresponsible people, your goal is to pick up and move someplace where you and your family can be safe and get some sleep.
The small block V-8 was not created in sub Saharan Africa. I rest my case.
The groups of humans that had to deal with more extreme yearly variations in weather and climate ie, More well defined seasons. Certainly had to adapt by being able to plan ahead, sometimes years in advance. This planning was one of the essential ingredients for developing a culture that valued creativity in dealing with environmental factors.
Meaning if you had to deal with seasons you either developed tools for dealing with them or you died out.
Virtually NOTHING was created in sub Saharan Africa, including written language or the wheel.
This article may be leftist propaganda, especially seeing as how we have recently unlocked DNA and anti-white leftists can no longer refute facts. It's actually an attack on real science.
