This perspective piece identifies key questions in sexual selection research, focusing on mate choice, signal evolution, genetic architecture, and speciation. It aims to stimulate discussion and guide future research directions in evolutionary biology.

Area of Science:

  • Evolutionary Biology
  • Behavioral Ecology
  • Genetics

Background:

  • The field of sexual selection has seen significant theoretical and empirical advancements.
  • A recent workshop convened experts to identify outstanding questions and stimulate discussion.
  • This perspective piece synthesizes these discussions into essential thematic areas.

Purpose of the Study:

  • To identify and deliberate on outstanding questions in sexual selection research.
  • To stimulate discussion and guide future research rather than provide a comprehensive overview.
  • To organize key questions into four essential thematic sections.

Main Methods:

  • The study is a perspective piece based on a "stock-taking" workshop.
  • It focuses on identifying and discussing unresolved questions in sexual selection.

  • Thematic organization includes mate choice, signal design, genetic architecture, and speciation.

    • Main Results:

    • Outstanding questions are organized into four themes: mate choice/mating systems, signal design (sender/receiver mechanisms), genetic architecture of sexually selected traits, and sexual selection/conflict as drivers of speciation.
    • Key areas for future research include understanding the evolution of mating systems, the neuroethology of receiver biases in signal evolution, the genetic basis of sexually selected traits, and the role of sexual selection in speciation.
    • Receiver biases are proposed as a potential null model for sexual selection.
    • The interplay between sexual and natural selection, and post-copulatory processes, are highlighted as important in speciation.

    Conclusions:

    • Resolving the identified themes can catalyze conceptual progress in sexual selection research.
    • Further research into these areas is crucial for advancing the field.
    • The study proposes potential avenues for future research to address these critical questions.
