Unformatted text preview: Eukaryotic Multicellular Ingestion The major taxonomic categories from most inclusive (biggest set) to least inclusive (smallest set) are: Domain, Kingdome, Phylum/Division, Class, Order, Family, Genus, Species Many species were originally distinguished by morphology. If 2 organisms look alike, they must be the same species. However, biological species are based on the ability to reproduce. The techniques of molecular biology have aided the taxonomist in the classification of organisms by allowing the DNA sequences from two organisms to be compared. (see scientific inquiery page 350) The ability to examine the DNA sequences and genes of different organisms resulted in the kingdom Monera being separated into two distinct groups. Carl Woese proposed that these two groups of bacteria are as different form each other as they are from the eukaryotes and that these differences arose very early in the process of evolution....
