Constructing Phylogenetic Trees: UPGMA Algorithm

This lecture introduces the UPGMA algorithm for constructing phylogenetic trees, explaining its simplicity and historical significance. The instructor discusses the importance of choosing relevant genes, aligning sequences, calculating distances, and iteratively building the tree. The lecture also touches on evolutionary concepts, genetic distances, and the implications of molecular clocks. Through practical examples and explanations, students learn how to apply the UPGMA algorithm to analyze genetic relationships and evolutionary divergence.
