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.
'Species' is an example of a taxonomic rank while Pannaria sphinctrina, a particular species, is an example of a taxon. Moreover, it is a taxon at species rank. Genus, family, order, class, phylum and kingdom are also examples of taxonomic ranks.
