    Study Notes

    Women’s Long-Term Mate Preferences

    • Women prioritize selecting mates capable of investing resources, favoring traits like financial prospects, social status, and ambition.
    • Preferences for physical protection include characteristics such as size, strength, bravery, and athletic ability.
    • Emotional investment and parenting skills are crucial, with traits like dependability, emotional stability, and positive interactions with children being significant.
    • Compatibility is established through similarity in values and lifestyle.
    • Healthiness in a mate is assessed by physical attractiveness, symmetry, and masculine features.

    Adaptive Problems and Strategies

    • Long-term sexual strategies showcase how women seek men who demonstrate resource-acquiring abilities, evidenced across diverse cultures.
    • Sexual selection manifests in intra-sexual competition (classifying superior traits within the same sex) and inter-sexual competition (mate choice based on advantageous traits).

    Parental Investment Theory

    • The discrepancy in parental investment leads women to be more selective in mating; they invest heavily in offspring through gestation and nurturing.
    • While females often prioritize men with financial security and social status, these needs shift according to individual circumstances and societal structures.
    • Men typically are more competitive due to having less invested in offspring; this competitive behavior is directly linked to their potential reproductive success.

    Selecting a Willing Partner

    • Dependability and evidence of love signal a partner's willingness to invest in long-term relationships and offspring.
    • Paternal investment is linked to offspring's reproductive success, enhancing social status and longevity for female partners.

    Men’s Adaptive Challenges

    • Men prefer mates with high reproductive value, typically indicated by youth and physical attractiveness.
    • Concerns over paternal certainty lead men to value chastity and sexual fidelity in partners, ensuring lineage preservation.
    • Similarity in values and intelligence fosters compatibility, while kindness and empathy facilitate effective child-rearing partnerships.

    Reproductive Values vs Fertility

    • Reproductive value reflects the potential number of offspring, while fertility quantifies actual reproductive output.
    • Indicators such as body proportions (e.g., waist-to-hip ratio) and biomechanical efficiency enhance reproductive success.

    Mechanisms for Detecting Ovulation

    • Humans lack clear estrous signalling, making ovulation detection a challenge; men who can identify fertile women gain reproductive advantages.
    • Cues for identifying ovulation include changes in skin color, voice pitch, and overall sexual receptivity linked to estrogen levels.

    Understanding Paternal Uncertainty

    • Uncertainty in paternity prompts evolved preferences for maternal chastity and sexual fidelity to ensure offspring genetic investment.
    • Men’s desires for faithfulness and loyalty in partners stem from the need to mitigate risks associated with paternal uncertainty.
