Within a cladogram, a branch that includes a single common ancestor and all of its descendants is called a clade. A cladogram is an evolutionary tree that diagrams the ancestral relationships among organisms. In the past, cladograms were drawn based on similarities in phenotypes or physical traits among organisms.

Each branch on the cladogram depicts a collection of creatures that have unique traits in common with one another.

What is a cladogram and its components?

  • An evolutionary tree that depicts the relationships between species' ancestors is called a cladogram.
  • In the past, cladograms were created using similarities among species' phenotypic or physical characteristics.
  • Today, cladograms can also be created using similarities among organisms' DNA sequences.
  • Each clade's constituent creatures are distinguished by common, comparable traits that separate them from every other organism in the cladogram.
  • A mammalian clade, for instance, would comprise all mammals. The evolutionary tree's stem is closest to the earliest common ancestors within a clade, whereas the branches furthest from it are formed by recently evolved species.
