What taxonomic feature is exhibited by the name *Jacana jacana*?
Answer
Tautonymy, where genus and species epithets are the same
The formal binomial nomenclature *Jacana jacana* demonstrates the linguistic phenomenon known as tautonymy. Tautonymy occurs when the genus epithet and the species epithet are identical. While this naming construct is not universal across all scientific names, its use in this case typically signifies a very close internal relationship within the genus *Jacana* or may reflect an early assignment made by Carl Linnaeus before extensive diversification within the group was fully documented or understood.
