The Biogeographic Origins of Novelty-Seeking Traits
https://www.econstor.eu/bitstream/10419/105054/1/V-366-14.pdf
"Abstract
This paper empirically investigates the biogeographic determinants of the human DRD4
exon III locus, a particular gene variant associated with the human
personality trait of novelty-seeking behavior. Providing a novel compilation of worldwide
DRD4 exon III allele frequencies in a large sample of indigenous populations around the world, this study
employs population-specific biogeographic characteristics using high-resolution geospatial
data. The estimates suggest that migratory distance from East Africa naturally selects
for specific novelty-seeking traits, even controlling for a broad range of biogeographic
determinants. Notably, land suitability for pastoral nomadism is significantly related to
DRD4 exon III diversity. This result provides further credence to the general observation
that novelty-seeking traits are quite common in nomadic populations , explaining why some
societies failed to settle and to develop centralized states"
