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.
Within each kingdom, species are further classified into groups based on similarities. For example, the full classification of a human is: 1  Domain Eukarya. 2  Kingdom Animalia. 3  Phylum Chordata. 4  Subphylum Vertebrata. 5  Class Mammalia. 6  Order Primates. 7  Family Hominidae. 8  Genus Homo.
