Resumen:
The relationship between the “individualism-collectivism” and the serotonin transporter functional polymorphism (5-HTTLPR), suggested in the previous reports, was tested in Native South Amerindian populations. A total of 170 individuals from 21 populations were genotyped for the 5-HTTLPR alleles. For comparative purposes, these populations were classified as individualistic (recent history of hunter–gathering) or collectivistic (agriculturalists). These two groups showed an almost identical S allele frequency (75 and 76%, respectively). The analysis of molecular variance showed no structural differencesbetween them. Behavioral typologies like those suggestedby JY Chiao and KD Blizinsky (Proc R Soc B 277 (2010) 529–537) are always a simplification of complex phenomena and should be regarded with caution. In addition, classification of a whole nation in the individualist/ collectivist dichotomy is controversial. The focus on modes of subsistence in preindustrial societies, as was tested here, may be a good alternative although the postulated association between the 5-HTTLPR S allele and the collectivist societies was not confirmed.
