I know teachers who work hard to enter the particular moral worlds of students. A high school teacher recently told me about his efforts not to condone but to understand why a student he admired had brought a gun to school.
In biological classification, rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, order, class, phylum, kingdom, domain, etc. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms.
1 In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and they, in turn, into orders, families, genera (singular: genus), and species (singular: species), with an additional rank lower than species. 2  a term for rank-based classification of organisms, in general.
