cladogram
This term describes a specific visual tool used in phylogenetics to map the hypothetical paths of evolution. It differs from a phylogenetic tree in that it focuses strictly on the branching patterns of shared derived characteristics rather than attempting to represent the actual chronological time or the exact length of evolutionary change.
Because it is a technical scientific term, it is used almost exclusively in academic, biological, or paleontological contexts. It carries a neutral, analytical connotation, serving as a hypothesis of relationship rather than a definitive proof of ancestry.
