What information does a cladogram show?

A cladogram is a diagram that represents the evolutionary relationships among various species or groups based on shared characteristics. It illustrates how different organisms are related through common ancestry, with branches indicating divergence over time. The positioning of species on the tree reflects their evolutionary lineage, helping to visualize the process of speciation and the relative timing of these events. Cladograms do not indicate the degree of change or the time scale involved, but rather the hierarchical relationships among taxa.
