White people did

how or what determins the black iq

Hence why they are smarter on average

so it takes 10,000 generations for their IQ to come back?

They didn't lose IQ

It's just they didn't develop it as they weren't studying for a long period of time.

Blacks used to but due to trade and scientific advancement not reaching them like China and Europe they didnt get the goodies

Ever seen rural people?

It's sort of like that but much more prolonged.

There are adopted black people in white families who have lower IQs

shit thats why Zulus and Axum empire was totaly different

hmm i shall evolve to make myself stupider

Yes, black people haven't been in academic focused countries for a long time.

That's why

Evolution isn't a conscious decision lol

Trade is the most important part in Civilization

good god you're retarded

Europeans learned about guns and gunpowder from China which led to guns

Says the American arguing other groups are more mixed than him.

Africans not much at all

Most African groups didn't even have written languages till the 1600s.

Blacks have been in a similar enviroment for hundreds of years and have the same differences in IQ they had when they first came

Similar enviroment?

Nice joke

I wouldn't call Congo's forests with no major rivers or ports which was completely detached from most of the world the same as Europe's fertile plains.

I'm talking about the United States you tard

It isn't instantaneous.

There have been free blacks here for hundreds of years

That's why.

How long does it take and why?

It's generational

yeah bro

How does that even work?

Dude the average life expectancy today is 80 years.

Caveman times it was 40.

That's still barely any generations.

they may have been socially disadvantaged for decades but they should've just gotten smarter

So you have blacks and whites living in the same enviroment for 300 years about and there IQ hasn't changed at all

No

>same environment
