Humans from Africa? This is crazier than flat Earth.

plus its full of Africans

I'm more in favor of the cold winter theory but what you describe could be part of the picture.

However, it's all kind of moot when you look at the haplogroup studies and realize that africans hybridized with an archaic hominid, possibly homo erectus, and the most recent common ancestor is at least 800,000 years back.

I won't totally discount it but all of those problems exist in other places too.

The west coast has a lot of cliffs, the same with Britain, australia, and western south america.

Plant killing insects and livestock killing parasites are completely global issues.

Impassable rivers exist all over the world, europe and america just diverted the misbehaving rivers to flatter terrain.

These are all challenges the other races overcame so long ago the problems are now uniquely african.

Darwin said that different conditions lead to different species evolving.

It's genetics... Africans aren't the same species as H. Sapien Sapien and are at least 150 thousand years less laterally evolved than the rest of humanity most likely do to 19% of there genes being of a very archaic ghost species most like homo erectus. Though history and terrain play a huge role most niggers are just smooth brains with smaller front lobes and progmathism. Bare that in mind while Europeans and Asians have 2% or more Neanderthal or Denisovan DNA niggers have up to 19% ultra archaic hominid ancestry. They are related to Lucy or Aardy 5 to 7 million years ago. Aryans came from the Cosmos and have spoken about that fact for thousand of years. The jews and marxist hide real history and truth about our origins.

All I know is niggers are dumb and violent , and should be avoided at all cost

Generally, the more inhospitable the region, the more adaptive the native human subset. The nigger did nothing. Ever. They just wallowed in mud, ironed their titties flat. Stretched their necks out of being functional, lips too, and ears.

So you are saying its not simply ((Jared Diamond's)) guns, germs (exposure) and steel (better resources) which made Europeans smart and productive, but mostly pure geographical features.

Still an external factor. But that's how evolution works. Don't forget about a colder, less lit climate.

And unlike Jared Diamond, don't forget the sacrifices Europeans made to attain their greatness, and what we have earn which we are now being tricked into giving it away.

European people and technology developed in a part of the world that experiences annual, no-growth freezing winters. That means you can’t grow or gather any food for five months at a time, every year.

Compared to many parts of Africa where you can grow, hunt or gather food year around, most of Europe faces a significant food supply challenge. Because Europeans did overcome this challenge we’ve lost our perspective on how difficult it was to overcome long winters. Technologies like food processing, food storage, winter shelter, heating systems etc. are not trivial technologies.

Additionally in terms of physical environment not every part of Europe was easy to live in. Much of Greece is mountainous which makes transportation or farming difficult. Do you think the ocean flooding that used to happen in the Netherlands was a trivial problem, yet they overcame it with a vast engineered system of dykes and dams.

Using their intelligence the Europeans were able to overcome various natural challenges in the environment. Africans were not.

If Europeans had developed in Africa they would’ve come up with ways to overcome Africa’s geographic limitations. You know with things like trains.

I like Thomas Sowell but in that video he kind of pussied out and tried to avoid the IQ issue.

If you exist in a culture without a written language how are you going to train any engineers to create sets of locks that might allow boats to navigate difficult sections of rivers. That’s not gonna happen and so African never developed or overcame its difficulties on its own.
