  • Mate regarding strategies eg monopolisation of woman's timepositivly corralated with domestic violence and aggression in relationships.
  • Corralation= aggression as a result of sexual jealousy= innate/adaptive response to reduce risk of cuckoldry & increase chance male can further lineage
  • Link between MRS and aggression= 72% of women who report experiencing MRS has been hospitalised after incident of domestic violence.
