What is Mate Choice and Sexual Selection?

Mate choice and sexual selection encompass the processes by which individuals select mates based on phenotypic traits like ornaments, displays, and genetic compatibility, driving evolutionary changes in animal populations.

This subtopic examines criteria for mate selection in birds, insects, and mammals, quantifying selection gradients and heritability of preferences. Key studies include Bateman's 1948 Drosophila experiments (3640 citations) demonstrating intra-sexual selection and Arnold's 1983 framework for measuring selection on morphology and performance (1722 citations). Over 10 highly cited reviews from 1948-2011 synthesize causes of variation in preferences and multi-cue usage.

Key Challenges

Why It Matters

Mate choice mechanisms explain sexual dimorphism and biodiversity generation, as quantified by selection gradients in Arnold (1983). Jennions and Petrie (1997, 1301 citations) link preference variation to mating system evolution, informing conservation amid human-induced changes noted in Sih et al. (2011). Applications include predicting evolutionary responses in insects (Bonduriansky, 2001) and songbirds (Koch et al., 2018, testing carotenoid signaling).

Key Research Challenges

Quantifying Preference Heritability

Estimating heritability of mate preferences requires longitudinal data on wild populations, complicated by environmental covariances. Arnold (1983) outlines statistical measures of selection gradients but notes variance-covariance challenges. Jennions and Petrie (1997) review genetic and non-genetic causes of variation.

Multi-Cue Integration Mechanisms

Females often use multiple sensory cues, but interaction effects are hard to disentangle experimentally. Candolin (2003, 1324 citations) evaluates hypotheses like signal redundancy and context-dependence. Andersson and Simmons (2006) highlight trade-offs in cue reliability across taxa.

Male Mate Choice Evolution

Male choice is understudied despite evidence in insects, with factors like operational sex ratio debated. Bonduriansky (2001, 1012 citations) synthesizes phylogenetic patterns and female trait evolution. Bateman (1948) provides foundational intra-sexual competition data.
