• What is natural selection's role in human adaptation?

  It helps humans adapt better to the environment and survive.
• What is sexual selection's purpose in human behavior?


  It helps to attract a mate and have healthy offspring.
• What is anisogamy in the context of human reproductive behavior?


  • Differences between male and female sex cells.
  • Males produce large quantities of sperm continuously from puberty to old age.
  • Females produce limited numbers of eggs, requiring more energy and time.
• Why do males and females use different strategies for reproductive success?

  Due to differences in the production and investment of sex cells.
• What do females look for in a male partner according to the study of Buss (1989)?


  Females look for partners who are committed and can provide resources.
• What did Buss (1989) find regarding females' partner preferences?


  Females universally place more importance on resource-related characteristics.
• What do males prefer in a mate according to Buss (1989)?


  Males prefer younger mates and value signs of a female's reproductive ability.
• Why do males experience more jealousy regarding sexual infidelity?

  Because it could result in raising someone else's child.
• Why are females more jealous of emotional infidelity?

  Because it may lead to the withdrawal of resources for her and the child.
• What is inter-sexual selection and its significance?

  • Also known as 'female choice'.
  • Females invest more time and resources in raising children.
  • They need to choose partners who provide the right genetic fit and resources.
• What is intra-sexual selection and its implications?

  • A strategy where males compete for female mates.
  • The winner reproduces and passes on successful genes.
  • It explains physical dimorphism between males and females.
• How does anisogamy influence male mating strategies?


  It suggests that quantity over quality is optimal for males.
• Why do males exhibit physical strength and aggression in mating contexts?

  Because sexual selection favors these traits for competing with other males.
• Why is there no evolutionary advantage for females to be larger or stronger?

  Because females do not need to compete physically for mates.
