Language of Origin: Ancient Greek
Story behind the word: The word 'homology' originates from the Ancient Greek words 'homos' meaning 'same' and 'logos' meaning 'relation'.
Evolution of the word: Originally used in biology to describe similar structures in different species that suggest a common evolutionary origin, the term 'homology' has since been adopted in various fields such as mathematics, linguistics, and anthropology to denote similarity or equivalence of structures or relations.
