The primary distinction between the two lies in the African golden wolf's wider skull and stronger teeth, according to National Geographic. Because they've both lived in the same desert environments, they've strayed little on the evolutionary path, which might be why they look so similar.
Not all the researchers are entirely convinced, but the Smithsonian Conservation Biology Institute thinks the case is closed.
"They have phenomenal data and they do a nice series of analyses. It's a super airtight case," bioarcheologist Greger Larson told National Geographic.
