A gene-culture coevolutionary model for brother-sister mating
1Department of Biological Sciences, University of Tokyo, Japan.
Abstract:
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.
