Evaluation

• Biological reductionist 


  - Male-female behaviour in relationships. Partner preference is reduced to the level of biology - gametes. Underestimates cultural differences.
• Biological determinism 


  - Male/female behaviour in relationships are determined by their biology, gametes that are produced.

  - Hard determinism which underestimates free will.
• Research support - Singh 


  -studied winners of Miss America and playboy centrefold.

  - Found the women displayed a 0.7 waist to hip ratio.

  - This supports that males have evolved preferences for traits which indicate fertility.
• Research support - Wayneforth and Dunbar

  - Carried out a thematic analysis of lovely heart columns. They found differences between male/females.

  - Males: they advertise resources and look for indications of fertility in females.

  - Females: Advertise youthfulness and being slim and look for men who are rich and have resources.
• Research Support by Clark and Hatfield

  - Aim: investigates gender differences to sexual offers.

  - Methods: male/female approached a member of the public of the opposite sex on a uni campus, propositioned them and recorded the amount who said yes.

  - Results: Men - 75% and female - 0% said yes.

  - Conclusion: Sexual selection supported by females who evolved to be highly selective when choosing a man.

  HOWEVER, low temporal validity - HIV/AIDS outbreak so less people are likely to randomly sleep together.
