Phylogeny and Cladistics

Phylogeny is the study of the evolutionary relationships between different groups of organisms. Phylogeny is based on the principle that organisms that are more closely related are more similar to each other than they are to organisms that are less closely related.

Cladistics is a methodHow a writer presents perspective or viewpoint through language/structure. of phylogenetic analysis that is based on the principle of shared characteristics. In cladistics, organisms are classified into groups based on the presence or absence of shared characteristics. Cladistics is used to construct cladograms, which are diagrams that show the evolutionary relationships between different groups of organisms. Cladograms are based on the principle of cladistics, which states that the more shared characteristics two groups of organisms have, the more closely related they are.
