Adaptation at the Levels of Fitness and Traits

Explore a comprehensive lecture on adaptation at the levels of fitness and traits presented by Luis-Miguel Chevin as part of the "Theoretical and Empirical Approaches to Understand Polygenic Adaptation" program. Delve into the complex world of biological evolution, focusing on the relationship between genetic variation and phenotypic traits. Discover how recent research has revealed the polygenic nature of many important traits, from crop yield to human height and complex diseases. Examine the current debate in evolutionary biology between adaptation through large changes in few genetic loci versus infinitesimal changes across numerous loci. Learn about efforts to integrate these contrasting views and expand the understanding of adaptive dynamics. Gain insights into quantitative descriptions of various adaptation scenarios and their connections to empirical data. This lecture, lasting 1 hour and 27 minutes, is part of a broader program featuring pedagogical lectures, research seminars, and interactive tutorial sessions, aimed at fostering a deeper understanding of polygenic adaptation.
