It must be that males across space and time have been specifically selecting for beauty in females. The less attractive females were apparently simply selected against.
We see this trend even in modern times as the Black phenotype in the US has remarkably merged with the White phenotype, but only from the late 1800’s on. The changes in Black skulls in the US from the 1870’s on are nothing short of miraculous. Some it is probably due to diet, but most of it seems to be due to pure genetics. At the same time, a remarkable change has occurred in the White phenotype in terms of selection against archaic features and for progressive features from the 1600’s to the present day such that White people now look more like Black people than they do like their very own Colonial ancestors.
We what we are seeing is a merger of the two races. We have already had the creation of the American Negro, almost a new race among Blacks characterized by more progessive features and greater beauty, fewer archaic features, increased intelligence (apparently genetic) and heavy White minority admixture. Yet US Whites are also creating a new race as they merge together with Blacks phenotypically. It is almost as if we are heading towards the creation of a new Black-White merged and somewhat mixed race here in the Americas. Some it is due to interbreeding, but much is also due to parallel development.
What happened what that after the First Liberation, Black men were probably finally able to be more selective in Black females. They selected for lighter skin and Whiter or at least more progressive features and against more archaic features. Black females were also able to be more choosy about men. As some Black men began to accumulate money and wealth (quite a bit of which could be accumulated in Black neighborhoods among the new Black professionals) women began selecting possibly for the most moneyed, prominent or powerful men.
This type of Black men has always been lighter-skinned and more White-admixed than other Blacks. Hence these men would have more progessive and fewer archaic features. It also seems to be a truism that archaic features as associated with lower IQ’s and more progressive features are associated with higher IQ’s. This is even true across racial lines and within races themselves. Mass Black selection for more progressive and Whiter features may have led to the increased IQ among US Negroes, which can only partly be explained by genetics. There may also have been some epigenetics at work here in the US.
