Genes, Culture, & Gender

Chapter 5: Genes, Culture, & Gender

Learning Objectives

  • Explore how distal factors of evolution and culture explain commonalities and differences in human nature.

  • Differentiate between sex and gender.

  • Identify examples of gender differences.

  • Define natural selection and evolutionary psychology.

  • Explain attraction and gender differences in attraction using evolutionary psychology.

Sex, Gender, & Spectrum

  • Sex: This refers to the biological categories of male and female, based on physical and physiological differences.

  • Gender: This encompasses the characteristics and roles that societies and cultures associate with males and females.

  • Spectrum: Understanding that both sex and gender exist on a spectrum rather than as binary categories.

    • Cisgender: Individuals whose gender identity aligns with the sex they were assigned at birth.

    • Transgender: Individuals whose gender identity does not align with their assigned sex at birth.

    • Note: The primary focus of the chapter will be on cisgender individuals.

Gender Differences

  • Gender differences can be observed in the following areas:

    • Basic physical attributes: Differences in physical characteristics such as strength, size, etc.

    • Aggression: Variations in aggressive behaviors between genders.

    • Sexuality: Differences in sexual behavior and attitudes.

    • Social Connectedness: How relationships and social interactions differ.

    • Social Dominance: Power dynamics and hierarchy in gender interactions.

  • Important note: Despite these differences, men and women are more similar than different overall.

Gender Differences: Nature vs. Nurture

  • Nature: Refers to biological and genetic factors that influence gender differences.

  • Nurture: Involves environmental, social, and cultural factors that shape gender identities and roles.

  • Debate: The ongoing discussion surrounding the contributions of nature vs. nurture in defining gender differences.

Shared Human Nature & Evolution

  • Natural Selection: The evolutionary process by which heritable traits that best enable organisms to survive and reproduce are passed down to subsequent generations.

  • Key principle: Traits that confer survival advantages are selected over time, shaping species' evolution.

Evolutionary Psychology

  • Definition: Evolutionary psychology explains cognition and behavior in terms of genetic factors that evolved over time as a result of natural selection.

    • It provides a framework for understanding human behavior through an evolutionary lens, linking our actions and social behaviors to historical survival needs.

Who is Considered Attractive?

  • The concept of attraction is explored from an evolutionary psychology perspective, identifying the traits that are generally perceived as attractive in individuals.

Attraction: An Evolutionary Explanation

  • Men and women are attracted to characteristics that are believed to enhance reproductive success:

    • Men tend to be attracted to physical appearance in women, which may signal fertility and health.

    • Women tend to be attracted to resources that men can provide, which may signify stability and support for offspring.

Learning Objectives (Reiterated)

  • Explore distal factors of evolution and culture in human nature differences.

  • Define culture, norms, and gender roles.

  • Understand cultural explanations for gender differences in attraction.

  • Define interaction and epigenetics.

  • Comprehend how social role theory illustrates an interaction between evolution and culture.

Differences Across Culture

  • Culture: The enduring behaviors, ideas, attitudes, and traditions shared by a large group of people and transmitted from one generation to
