Exam Review – January 2013 Diversity Unit - List taxonomic ranks in order. What is the significance of this order? Domain‚ Kingdom‚ Phylum‚ Class‚ Order‚ Family‚ Genus‚ Species. Classification of species: kingdoms contain many different types of organisms‚ each taxon contains progressively fewer types of organisms‚ taxon “species” is narrowest category‚ containing only one type of organism. As you go from kingdom to species‚ organisms share more and more in common. - Explain and give an example
