This course provides a straightforward introduction to phylogenetic trees. Designed for all learners who want the knowledge and skills to read, interpret, and apply core phylogenetic concepts to their interpretations of evolutionary history.

This course covers common phylogenetic groupings, focusing on sister groups, monophyletic, paraphyletic, and polyphyletic classifications. Each set of lessons covers how to identify these groups as well as their implications for evolutionary relationships. Topics covered include why birds are considered reptiles, why polyphyletic groups are useful for ecology but not evolution, and why we create these groupings in the first place.

This course tackles common misconceptions and nuances surrounding phylogenetic trees and evolutionary relationships. By critically examining these issues, students will learn how to accurately interpret phylogenies, avoid oversimplifications, and appreciate the complexities of evolutionary thinking. This course works to dispel misconceptions about "advancement" in evolutionary thinking and correct common misunderstandings of phylogenetic relationships.
