National Geographic – Coywolf : Wild Hybrid Animals ( Coywolf Documentary )
Initially this animal was initially called coydog, then eastern coyote, and now coywolf with eastern (or northeastern) coyote being the generally accepted term for this animal.
We can estimate the date of the most recent hybridization events that created eastern coyotes by analyzing their genetic structure. Their DNA show that about 100 years ago, coyotes mated with wolves, and about 50 years ago with dogs. A century ago, wolf populations in the Great Lakes were at their nadir, living at such low density that some reproductive animals probably couldn’t find another wolf mate, and had to settle with a coyote.
