domain Bacteria - domain of unicellular prokaryotes that have cell walls containing peptidoglycans. homologous structures - Structures in different species that are similar because of common ancestry. classification - the process of naming and assigning organisms or groups of organisms to a taxon analogous structures - have the same function in different groups but do not have a common ancestry analogy - similarity due to convergence ancestral traits - more primitive features, such as te...
