An interesting article discusses the inheritance of higher intellectual characteristics. It was previously believed that the genome is divided into the protein-coding region and the rest of the genome is "Junk DNA" unnecessary for inherited characteristics. The article tackles the problem of why, for example, measured intelligence cannot be derived solely from the coding DNA region. The conclusion is that the inheritance of intelligence is not due to genes at all, but is culturally inherited from parents to children, or that the inheritance of higher intellectual functions is complex, related also to the "Junk DNA". In practice, sociological and racial concepts have been associated with the study of intelligence in particular. These have traditionally been associated with the hierarchies of groups, which makes the study challenging. The dilemma arises whether to accept purely genetic differences among individuals or whether to accept individual differences as a social hierarchy. Neither option seems like a "good" explanation, not even a combination of the two. The last word has not been given in this assessment either.
