Development of Evolutionary Theory

Explore the history of evolutionary thought in this week's agenda, understanding the four key fields of study in evolutionary theory. Discuss biological variation, the scientific method, natural selection, and the impact of inherited traits on evolution. Discover how natural selection operates on populations and influences adaptations over long time periods. Get ready for the Sickle Cell Exercise and delve deeper into the concepts of genetic variation and selective advantage.
