this is not news...it's old stuff printed for the public today.
UB,
Research has shown Eastern Coyote has Wolf pedigree. This has been studied and documented for 50+ years or so. One fact that always stood out to me is Eastern Coyote Skull (plates) are wolflike, much different than Western Coyote. It's true that western Coyote have bred with Wolf.
On a note about CoyDogs...Coyote will breed with Dog to fill a void. The bloodline is usually short lived. Reason being Dog mate doesn't help raise litter. Both Coyote partens help raise litter. Dogs don't (dog genes). So if Dog is in the bloodline, chance of survival (of bloodline) goes down. Yes there are Coydogs for a few generations then fizzle out.
Hybridiaztiong between Grey Wolves and Coyotes oocured in the wild in eastern North America. Possibly 2 episodes, one between Minnesota and Southwestern Ontario, Wolves and Coyotes bred. Then the second episode Wolves/Coyotes bred in southeastern Ontario, Quebec, New England & Atlantc Canada.
These movements were traced by mtDNA genotype frequence data.
Data from studys in southeasten USA shows Coyote and Red Wolf bred.
