Foundations of Phylogenetics: Reconstructing Evolutionary Trees

Understanding how species evolved and how they are related is fundamental to modern biology. This text-based course introduces you to the core principles of phylogenetics, guiding you from basic evolutionary concepts to modern tree-building methods. By reading through our structured explanations and analyzing real-world scenarios, you will develop the skills to read, interpret, and construct phylogenetic trees. You will gain a solid foundation in evolutionary analysis, enabling you to confidently discuss and apply phylogenetic workflows in academic or research settings. What you'll learn: - Understand the fundamental concepts of evolutionary history, homology, and tree terminology. - Learn how to prepare and align molecular sequences for phylogenetic analysis. - Compare distance-based and character-based methods of tree reconstruction. - Apply modern statistical frameworks, including maximum likelihood and Bayesian inference, to evaluate evolutionary models. - Interpret phylogenetic trees to draw accurate biological conclusions. - Explore modern software workflows and computational tools used in contemporary research. The course begins with essential evolutionary terminology before progressing to sequence alignment, tree-building algorithms, and modern statistical evaluation techniques. Each concept is reinforced with written case studies and practical interpretation exercises. This course is designed for students, researchers, and science enthusiasts who are new to bioinformatics and evolutionary biology. No prior experience in phylogenetics or programming is required.
