Wolves (canis lupus), coyotes (canis latrans), and domestic dogs (canis familiaris) are closely-related species. Through DNA analysis, scientists have established that the wolf is the ancestor of the dog. Dogs and wolves are so closely related that DNA analysis cannot distinguish a wolf from a dog or a wolfdog hybrid.

Demographic change can influence the underlying growth rate of the economy, structural productivity growth, living standards, savings rates, consumption, and investment; it can influence the long-run unemployment rate and equilibrium interest rate, housing market trends, and the demand for financial assets.

The U.S. population increased by 10 percent between 2000 and 2010 and is projected to increase by 8 percent between 2010 and 2020, from 309 million to 333 million.

Coyotes and dogs are related, and they are biologically capable of producing hybrid litters. Coydogs have been raised in captivity.

Don’t worry, coywolves aren’t that dangerous; they will probably shy away if they see you. Nonetheless, it’s good to keep in mind that they’re top predators — and coyotes are known for having attacked people before.

Coywolf is an informal term for a canid hybrid descended from coyotes, eastern wolves and gray wolves. All members of the genus Canis are closely genetically related with 78 chromosomes and therefore can interbreed.

Although hybrids are typically less fit than straight species, the story of coywolves in the Northeast might be one of success. “In this case, the hybrid has become more adapted.” Another advantage of coyotes and wolves mating is that, unlike many interspecies relationships, their offspring are fertile.

I have previously found coywolves to be significantly different in body size from both western coyotes and eastern wolves. However, they are closer to coyotes whereby eastern wolves are 61-71 percent heavier than the same-sex coywolf, while coywolves are 35-37 percent heavier than western coyotes.
