The genetic evidence is very strong.
- Gene pools differ by population
- Genes that have been identified among different populations code for differing phenotypic outcomes (say; testosterone levels) which is consistent with what evolution would predict for genes that attain a broad prevalence within a population
- There was never a time in the past when the current general order of intellectual or physical successes among the SIRE group “races” was reversed…i.e., there was no time when sub-saharan africa was dominant for inventions or technology or the like. This pattern is consisten into modern times in all cultures, all political systems and all social structures.
- In modern times, we can normalize nurturing influences such as opportunity, education, health, nutrition, parental education and so on. To date, when we compare groups with normalized opportunity, the differences for skillsets persist, and no nurturing influence has been identified that accounts for this. What’s left is genes.
In simple terms, the black SIRE group is “dumber” (to put it pejoritavely) for intellectual averages and “faster” for sprinting averages. This has been repeatedly and consistently measured. The question is, “Why?” and the answer is, “gene prevalence differences, because nurturing differences can be normalized and normalizing them does not eliminate the average gap.”
