Offspring of a horse and donkey are unable to reproduce.

Horses and donkeys are not of the same species when defined by reproductive isolation because: Offspring of a horse and donkey have a unique morphology. They are unable to interbreed. Offspring of a horse and donkey are unable to reproduce. They do not have similar morphology.

There may be no common name for an organism. Names mean different things to different people. Foreign names may not be understood. Many names may exist for the same organism.

Problems in using common names to universally identify living things include: Enough common names are not available to name every living thing. Common names lack sufficient precision. There may be no common name for an organism. Names mean different things to different people. Foreign names may not be understood. Many names may exist for the same organism.

the International Code of Nomenclature
