∑ - All organisms are classified into three domains. The Archaea and Bacteria domains are prokaryotes. These are organisms that do not have a membrane bound nucleus and their DNA is not associated with proteins. The Bacteria domain consists of Eubacteria and archaebacteria The Eukarya domain includes eukaryotes, or organisms that have a membrane bound nucleus. This domain is further subdivided into the kingdoms Protista, Fungi, Plantae, and Animalia Groups organisms primarily based on differences in ribosomal RNA structure. Ribosomal RNA is a molecular building block for ribosomes. - The principal taxa for classifying eukaryotes are kingdom, phylum, class, order, family, ∑ genus and species. - In a natural classification, the genus and accompanying higher taxa consist of all the ∑ species that have evolved from one common ancestral species. For natural classification, it is assumed that all members of that group shared a common ancestor at some point in their history. This can be seen in their structure. Unnatural or artificial classification for example would be birds and flies. They both can fly; however flight evolved separately, and they are classified separately - Application: Classification of one plant and one animal species from domain to species β level. Research one plant and one animal example and fill out the table below. Taxa Human Gray Wolf Kingdom Animalia Animalia Phylum Chordata Chordata
