These critters we're talking about are RACES ~ not even subspecies.
A Jackel is a subspecies of the same species as the wolf-dog-ote!
Their mitochondrial DNA is distinctly wolf.
Wolves and coyotes are distinct species if species (a word humans made up as an imprecise guide to reality) is to have any meaning at all.
A swamp may well have many plants and features in common with a forest - and some forests may be turning into swamps and some swamps turning into forests - but that doesn't mean that “swamp” and “forest” mean the same thing.
