PERSPECTIVE: INDIRECT MATE CHOICE, COMPETITION FOR MATES, AND COEVOLUTION OF THE SEXES
1Department of Biology and Curriculum in Ecology, University of North Carolina, Chapel Hill, North Carolina, 27599-3280.
Summary
Sexual selection includes direct mate choice and indirect mate choice. Indirect mate choice, often overlooked, broadens the scope of sexual selection and coevolutionary influences on species.
Area of Science:
- Evolutionary Biology
- Behavioral Ecology
Background:
- Charles Darwin identified male competition and female choice as key mechanisms of sexual selection.
- Most research has focused on direct mate choice, involving individual discrimination.
Purpose of the Study:
- To distinguish between direct and indirect forms of mate choice.
- To explore the broader implications of indirect mate choice for sexual selection and coevolution.
Main Methods:
- Conceptual framework development to classify mate choice mechanisms.
- Analysis of behaviors and morphologies that restrict mating opportunities.
Main Results:
- Introduced direct mate choice (individual discrimination) and indirect mate choice (restricting mate pool).
- Identified various forms of indirect mate choice, including advertisement, evasion, aggregation, and location preference.
- Demonstrated that indirect mate choice can facilitate competition and lead to assortative mating.
Conclusions:
- Indirect mate choice significantly expands the recognized scope of sexual selection.
- Sexual selection, through both direct and indirect mechanisms, has pervasive influences on the coevolution of sex-specific traits.

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

01:06Natural Selection and Mating Preferences
620
The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.

In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.

Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...
