Systematists use phylogenetic trees to graphically represent hypothesized evolutionary relationships among organisms.

Phylogenetic Trees

Diagrams that represent the evolutionary relationships among various biological species or other entities, based upon similarities and differences in their physical or genetic characteristics.

Systematists

Systematists are scientists who study the classification and evolutionary relationships among organisms, organizing them into systems of taxonomy.

Evolutionary Relationships

Descriptions of how different species are connected to each other through common ancestors, detailing the path of divergence and speciation.
