Evolutionary Biology Exam Review
Course Introduction
Evolutionary Biology explores the processes that have shaped the diversity of life on Earth, focusing on mechanisms such as natural selection, genetic drift, mutation, and gene flow. Students will examine the historical development of evolutionary theory, the evidence supporting it, and the ways in which evolution influences the adaptation and speciation of organisms. The course also addresses topics such as population genetics, phylogenetics, and the evolutionary relationships among major groups of organisms, providing a comprehensive understanding of how evolutionary forces operate at both the molecular and ecological levels.
