摘要
We present a gene-culture coevolutionary model for brother-sister mating in the human. It is shown that cultural-as opposed to innate-determination of mate preference may evolve, provided the inbreeding depression is sufficiently high, At this coevolutionary equilibrium, sib mating is avoided because of cultural pressures.
