HOMOLOGY. In biology, a HOMOLOGY is a characteristic shared by two species (or other taxa -- a taxon is the generic term for a classification group such as a Kingdom, a Phylum, etc.) that is similar because of common ancestry.ou can't call something primitive or derived without comparing it to something else. Biosystematists often use the existence of shared characters in related taxa to help reveal their common ancestry. 1  a SYMPLESIOMORPHY is a shared, primitive character. 2  a SYNAPOMORPHY is a shared, derived character.
