![The simple fact is this:IQ matters. With low IQs you get a 5 man basketball team, an 11 man football team that has to be told each play one at time Africa and a motown. With a high IQ you get Rome, Athens, the Olympics, and 50 piece orchestras. Think of IQ as height and nignogs be midgets. [290x174 - 14KB]](https://pic8.co/sh/AjMDcQ.jpg){kind=link}
Indians and Chinese scientists scientists are not jewed and are highly interested in this research. Other non-anglosphere countries as well.
Cranial size seems to be largely a function of climate. It is a penalty to have a big noggin in hot climates and other populations like abos have the same issue. Maintaining body heat.
So I would say this is partly why they have lower IQ. The pressure to have a smaller cranium for improved thermodynamic function outweighed the need for a big brain need to plan out the most efficient use of resources, particularly since resources are plentiful in africa, if you can kill the other dudes around you.
Instead of thinking about why africans have an atrophied brain, consider why caucasians and east asians have such a hypertrophied brain.
Of course some of these disparities could come from genes from introgression of non-homo sapiens populations. Neanderthal had a big head. Denisovan had a smaller head than us. What was the ghost population that west africans and bantu have ancestry from? He lived in africa so its not likely that he had a big head either.

semites live in worse heat than blacks and they look rather human, north africa, middle east are tropical deserts. denisovans that settled near the equator like south asians and the pacific islanders dont seem to have a heatsink problem and are not known to be dumb as marbles(though i have not had the occasion to meet one to verify)
“Semites” , i.e. Most of the people living in the levant, like palestinians, syrians, lebanese, have low iqs. Most middle eastern and north africann countries have IQs in the 80s. I don’t know what their cranial volume is. They still have higher IQ and cranial volume than SS africa probably because
They are more likely to have ancestry from cold climates than SS Africans within the last 50 thousand years.
The middle east was not such a hot hell hole just 3 or 4 thousand years ago. Remember that that was a fairly temperate area at the end of the last ice age . The sahara and arabian deserts did not exist.
Addendum. Jews have a particularly unique genetic history over the last 4000 years or so which makes them different from their fellow semites. I personally believe they descend from a largely endogamous priestly cast which would have occasionally recruited from the larger population for traits like hi IQ traits ( and showmanship/manipulation and “your donations are needed” sort of tendencies). And theyve recruited from European and Caucasus populations as well. So they’re not the best example of Levantine populations.
