WebbSpecies that evolve share some, but not all, traits with their ancestors. To establish phylogeny, scientists must distinguish shared derived characters from shared ancestral characters. Shared derived characters are unique to a specific clade. Shared ancestral characters are found in the clade under study as well as older clades. Webb16.3 Taxonomy And Systematics. Taxonomy (from Ancient Greek taxis, meaning ‘arrangement’, and nomia, meaning ‘method’) is the science of defining and naming groups of biological organisms on the basis of shared characteristics.
