The phylogeny you see below represents the basic relationships that tie all life on Earth together. This tree, like all phylogenetic trees, is a hypothesis about the relationships among organisms. It illustrates the idea that all of life is related. Webbphylogenetic tree. Activity 4: Building a Phylogenetic Tree from DNA Sequences – Students will use a hierarchical clustering method to reconstruct a phylogenetic tree from their simulated DNA sequences. Length: 1-2 hour class periods, depending on homework and discussion Intended Participants: High school and/or middle school students.
