means The scientific study of similarities and differences in the body structures of different species, used to understand evolutionary relationships and function.

from Straightforward Latin-via-English build: 'comparative' from Latin comparare, 'to pair, match, liken' (com- 'together' + par 'equal'), and 'anatomy' from Greek anatomē, 'a cutting up' (ana- 'up' + temnein 'to cut'). The discipline itself crystallized as a named field when naturalists like Cuvier began systematically dissecting and comparing animals across species, turning the dissecting table into a tool for spotting shared blueprints beneath wildly different skins.
