Cladograms

Mr. Anderson explains cladograms, which are hypotheses about the relationships between organisms based on shared characteristics. He discusses how to create a cladogram, the concept of outgroups, and the importance of common ancestors. The video also covers adding new species to a cladogram and the principle of parsimony, which suggests the simplest explanation is often the best. Modern cladograms use DNA sequencing to determine evolutionary relationships.
