Explanation:
Detailed explanation-1: -To some biologists, use of the term “cladogram” emphasizes that the diagram represents a hypothesis about the actual evolutionary history of a group, while “phylogenies” represent true evolutionary history.
Detailed explanation-2: -Phylogeny refers to the evolutionary history of the development of a species or of a taxonomic group of organisms. The phylogenetic relationships are depicted in the form of a phylogenetic tree, i.e. a tree diagram depicting how one taxon is closely or distantly related to another taxon.
