Male transfer in olive baboons

STUDIES of human populations have shown that inbreeding results in an increase in the number of offspring with greatly reduced viability. It seems likely that there are similar effects in other primates. In Papio anubis it seems that this problem is reduced by the transfer of males between groups. In a population studied at Combe National Park in western Tanzania inbreeding may be essentially avoided through the transfer of all males out of their natal troop.
