Abstract excerpt

Inbreeding can reduce fitness and genetic diversity, posing significant challenges for small human populations. While mobility and exogamy are known mechanisms of inbreeding avoidance among hunter-gatherers, the effects of cultural systems in mitigating these risks have not been studied in detail. Here, we investigate inbreeding patterns and avoidance strategies in the Raute of Nepal in comparison with two other...
