Things may be classified either because they are of the same genus or kind, that is to say, because they had the same origin; this gives us a genealogical classification: or they can be classified because they have the same appearance, eidos, or form, without claiming for them a common origin; and this gives us a morphological classification.

It was, however, in the Aristotelian, and not in its etymological sense, that the Greek eidos was rendered in Latin by species, meaning the subdivision of a genus, the class of a family.
