EVOLUTIONARY

1. EVALUTATION

   • Some critics feel evolutionary
     • Justify violence by men against women
       • As natural and evitable
   • Evolutionary perspective offers
     • An explanation of how aggressive behaviour occurs
       • Due to suspicions of infidelity may arise
         • Via natural selection
         • Face validity

     • Females always certain of maternity
       • Reproductive problem
         • Finding male willing to invest resources
         • Into her and children in long term
   • Evolutionary explanations of aggression
     • See aggression use as a survival function
     • In order for procreation potential
   • Evolutionary explanation for infidelity and jealousy
     • Related to evolutionary approach to mating behaviour
     • With intersexual selection indicating
       • Gender differences in what men/women look for
         • In potential partners

3. RESEARCH

   • Daly & Wilson
     • Link between sexual jealousy & aggression
     • 58/214 murders had sexual jealousy
       • Underlying cause
     • 27% murders
       • Motivated by sexual jealousy
     • Men use aggression
       • Constrain females
         • Greater confidence in paternity
   • Dobash & Dobash
     • Domestic abuse on females
     • Main assault
       • Sexual jealousy

4. IDA

   • Reductionist
     • Excludes psychological explanations
       • Such as SLT
   • Individual differences
     • Cannot account for them
     • Why males react differently with the same adaptive problem
   • Deterministic
     • Little or no control of our behaviour
     • Controlled by biological
   • Cultural differences
     • In murder rates of wives by husbunds
     • And in the degree of anxiety felt
       • In responses to sexual infidelity by males
     • Suggest that factors other than those
       • Determined by evolution play a part
