Developmental defects are expected to be common and severe in the early evolution of parthenogenesis, and they could help to explain the predominance of sexual forms of reproduction. It is difficult, however, to see how such defects might explain the ecological and phylogenetic correlates of sex. Here we suggest that internally fertilized animals that brood their young may be more susceptible to invasion by parthenogenetic mutants. The reason is that brooders could establish 'selective arenas… CONTINUE READING
