>>19970851GENETICS AND SELECTION:
Cultures and tribes where mate selection was based on animalistic and naked/semi-naked mating rituals (Dancing around a campfire waving your dick around) depends on the female choosing a mate, and the genetics of their children based on dick size, and the IQ of the male is not even considered. This may work in primitive, unevolved, uncivilized societies, but produce low IQ high-physical offspring. After many generations, the whole 'tribe' or population has 'evolved' to be low IQ, and a side effect may be 'MUH DICK'.
In other evolved and high IQ societies, the children are the products of parent selection based on Prospects, ability, IQ, Intelligence, skills, knowledge, etc etc everything that is required for an individual to be HIGH-FUNCTIONING in a HIGHLY DEVELOPED and HIGH FUNCTIONING SOCIETY. After many generations, that 'Tribe' or Society will be more intelligent and effective than previously.
In the second case, 'DICK SIZE' is never considered, as the values aof the Parents are whether the partner of their child is going to be a positive producer, and be a net benefit to the Family. 'MUH DICK' is not even a consideration, in fact if the daughter goes out looking for 'MUH DICK' she will be disowned, dis-inherited and in some cases killed for putting 'MUH-DICK' above the honor and values of the family.
Short story long, if a group has the 'MUH-DICK' characteristic, then their whole population has been bred with intelligence, ability, knowledge and skills coming a very far second to 'MUH-DICK', and have evolved to be retarded as a race.
Societies that have chosen based on intelligence, skills, abilities, family standing etc etc and NEVER EVEN CONSIDER DICK SIZE are the high value, high ability, high intelligence societies that have developed advanced civilizations.
There you have it.
