f high iq was selected for in Africa, would ‘ progressive features’ be selected for at the same time, eg less prognathism etc? (I assume wide noses and large lips are related to climate and not intelligence, right?)
is there any study that suggests prognathism correlates with iq presently?
wow this discussion is about as politically incorrect as it comes.
Being politically incorrect is the definition of Beyond Highbrow.
Well, yes, more progressive types tend to have higher IQ’s for whatever reason, and more archaic types tend to have lower IQ’s for whatever reason. So any time a race is getting more progressive phenotypically, it is generally a good thing IQ-wise.
In the last 100 years, US Blacks have changed massively in the direction of more progressive phenotypes. Apparently most of it was natural evolution, probably due to selection pressure – Blacks were preferentially selecting mates that had more progressive features. The US Black IQ may have gone up 7-8 points during that period. Certainly US Blacks may be 15 IQ points above Caribbean and African Blacks, so maybe this independent evolution they underwent here in favor of more progressive features had something to do with it.
I do not want to discuss prognathism much except to say that prognathism is an archaic features and groups with high prognathism tend not to have high IQ scores. But I am not sure how low their scores are either. Some Amerindians are rather prognathous, and their IQ is 87. That’s not really low. I am not sure which races other than Africans are prognathous, honestly.
