IS MIGRATION KIN STRUCTURED

We estimate the strength of kin-structured migration in six human popu lations (five from New Guinea and one from Finland) and in one populat ion of nonhuman primates. We also test the hypothesis that migration i s not kin structured by generating a sampling distribution of the esti mator under the null hypothesis of independent random migration. We ar e unable to detect a statistically significant level of kin-structured migration in any population. However, five of our six human populatio ns were from Papua New Guinea, and we cannot dismiss the possibility t hat migration is kin structured in other parts of the world.
