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.
