Phylogenies are the evolutionary relationships among organisms, depicting their ancestry and descent. Synonyms for the term include cladograms, dendrograms, genealogies, and evolutionary trees. Cladograms focus on the relationship of organisms based on shared characteristics, while dendrograms are more commonly used in the study of molecular genetics. Genealogies refer specifically to the lineage of genetic traits in an organism, while evolutionary trees display a visual representation of the diversification of species over time. Whether referred to as phylogenies, cladograms, dendrograms, genealogies, or evolutionary trees, the study of these relationships is crucial to understanding the true nature of biodiversity and the evolutionary history of life on our planet.
