Human Sexual Attraction and Evolutionary Mating Theory (copy)

Natural Selection

The process by which organisms possessing traits better suited to their environment have higher survival rates and reproduce more frequently.

Survival of the Fittest

A phrase synonymous with natural selection, indicating that only those organisms best adapted to their environment survive.

Darwin's Finches

A group of approximately 15 distinct finch species observed by Darwin, demonstrating adaptation through beak morphology to different food sources in the Galapagos Islands.

Industrial Melanism

The phenomenon where darker-colored organisms become more prevalent in industrial areas due to selective advantages in camouflage.

Peacock Paradox

The evolutionary question of how elaborate male traits, which may hinder survival, can persist if they attract mates and increase reproductive success.

Sexual Selection

The theory proposing that certain traits evolve because they provide advantages in mating, even if they compromise survival.

Intrasexual Competition

Competition among members of the same sex, typically males, for access to mates.

Intersexual Selection

Selection of mating partners based on specific traits, usually driven by female choice.

Fisherian Runaway Selection

A positive feedback loop in which a male trait linked to female preference becomes exaggerated over generations.

Sexy Son Hypothesis

Hypothesis where females choose attractive males to increase the likelihood of producing attractive sons, enhancing reproductive success.

Parental Investment Theory

Theory suggesting that the sex investing more resources in offspring will be more selective in mate choice.

Good Genes

A concept suggesting that females prefer males with high genetic quality to ensure healthy offspring.

Resource Provisioning

The historical access to resources that men could provide for women and offspring, influencing mate choice.

Cross-Cultural Study (Buss, 1989)

A study examining mate preferences across 37 cultures, highlighting universal traits desired in mates.

Olfactory Signals

Chemicals emitted by individuals that can influence mate preferences based on genetic compatibility.

Acoustic Signals

Vocal cues such as pitch that may indicate male health and dominance.

Mate Copying

The phenomenon where individuals use the mating choices of others to inform their own mate selection.

Facial Symmetry

A trait reflecting genetic quality, associated with attractiveness across various species.

Status Preference

The evolutionary drive for individuals to prefer mates with higher status, due to associated benefits.

Waist-to-Hip Ratio (WHR)

A physical trait ratio that is perceived as attractive and correlates with health and fertility.

The Bad Boy Phenomenon

The tendency for women to be attracted to men who display risk-taking and rebellious behaviors, potentially linked to status.
