New analyses of the human genome have established that race has a biological basis. Biologists scanned various genomes for evidence of natural selection. They detected signals of many genes that have been favored by natural selection in the recent evolutionary past. According to the analyses, the difference between races seems to stem from relative allele frequency. Therefore, it is not true that race is only a social construct.
The genetic analysis explains the emergence of high cognitive ability among Jews. The average verbal IQ of a Jew is 120, the highest score among all races.
This implies that the genes affected by natural selection control not only the expected traits (such as skin color and nutritional metabolism) but also some aspects of brain function.
Overall, race appears to be both a biological and a social construct. We can, therefore, use the word "race" to describe Jews.
