What is one key factor in the debate of whether Neanderthals are a separate species from modern humans or a
subspecies? What will be an ideal response?
If Neanderthals were a subspecies, their species name would be Homo sapiens
neanderthalensis. If they were a separate species, their species name would be Homo
neanderthalensis. If it could be shown that modern humans and Neanderthals interbred and
produced fertile offspring, then it would suggest that they were a subspecies.
