Cladograms
A cladogram is a reduced evolutionary tree that shows the branching pattern indicating the inferred time from the divergence
Cladograms are now based on amino acid or base sequences and depends on 2 main scientific ideas. The cladogram represents how time flows in one direction only. Common ancestors of related species become apparent prior to these descendants in time. The cladogram can also show that life forms are closely related if they share new features or if a common characteristics appeared in both common species.
In the tree diagram, the branching points are called nodes which represent a hypothetical ancestral species that split into 2 or more species. Computer programs also develop how species evolve because of the variations of the base or amino acid sequence. This is known as the principle of parsimony but this theory doesn't prove how the clade evolved, only explains the sequence of divergence in clades.
