A new species is evolving before scientists’ eyes in the eastern United States.
Wolves faced with a diminishing number of potential mates are lowering their standards and mating with other, similar species, reported The Economist.
The interbreeding began up to 200 years ago, as European settlers
pushed into southern Ontario and cleared the animal’s habitat for
farming and killed a large number of the wolves that lived there.
That also allowed coyotes to spread from the prairies, and the white farmers brought dogs into the region.
Over time, wolves began mating with their new, genetically similar neighbors.
The resulting offspring — which has been called the eastern coyote
or, to some, the “coywolf” — now number in the millions, according to
researchers at North Carolina State University.
Interspecies-bred animals are typically less vigorous than their parents, The Economist reported — if the offspring survive at all.
That’s not the case at all with the wolf-coyote-dog hybrid, which has developed into a sum greater than the whole of its parts.
At about 55 pounds, the hybrid animal is about twice as heavy as a
standard coyote, and her large jaws, faster legs and muscular body allow her to take down small deer and even hunt moose in packs, and the animal
is skilled at hunting in both open terrain and dense woodland.
An analysis of 437 hybrid animals found that coyote DNA dominates her
genetic makeup, with about one-tenth of its DNA from dogs, usually
larger dogs such as Doberman pinschers and German shepherds, and a
quarter from wolves.
The animal’s cry starts out as a deep-pitched wolf howl that morphs into higher-pitched yipping — like a coyote.
Her dog DNA may carry an additional advantage.
Some scientists think the hybrid animal is able to adapt to city life
— which neither coyotes or wolves have managed to do on their own —
because her dog ancestry allows her to tolerate people and noise.
The coywolves have spread into some of the nation’s largest cities —
including New York, Boston and Washington — using railway corridors.
The interbreeding allows the animal to diversify her diet and eat
discarded food, along with rodents and smaller mammals — including cats,
which coywolves eat skull and all — and they have evolved to become
nocturnal to avoid humans.
The animals are also smart enough to learn to look both ways before crossing roads.
Not all researchers agree the animal is a distinct species, arguing
that one species does not interbreed with another — although the
hybrid’s existence raises the question of whether wolves and coyotes are
distinct species in the first place.
But scientists who have studied the animal say the mixing of genes
has been much faster, extensive and transformational than anyone had
noticed until fairly recently.
“(This) amazing contemporary evolution story (is) happening right
underneath our nose,” said Roland Kays, a researcher at North Carolina
State.
THIS SHIT IS SO WILD AND IT’S ABSOLUTELY FASCINATING. If you’d like to watch the entire Nature documentary referenced in that “watch this report” link, you can find the whole thing on Youtube. It’s a terrific documentary and a really interesting look at an animal most people don’t even seem to realize exists. The extent to which coywolves have adapted to urban life and the ways in which they’re very distinct from the species they’ve sprung from is pretty incredible.

HOT DAMN I WANT COYWOLF DOGGL
See, I first heard about this a few years back, but I thought it was a mislabelling of the Carolina Pariah Dog. So it is actually a distinct breed?
What I had first heard is that they hunt like wolves, scavenge like coyotes, but will totally beg and butter you up for your fries like a dog. Like they’d much rather become your friend for food if they can, since it’s easier than eating your kids.
if straight girls knew of even half of how much lesbians and bisexual girls hold themselves back and restrain themselves and dilute themselves in order to appear non-threatening and non-predatory to those same straight girls
once we’ve made you aware of our orientation, we barely allow ourselves to look at you and smile at a joke you just told, in case you’d assume we’re into you, just because we smiled at you once
but guys can catcall, make inappropriate comments, talk about girls as trophies, talk about how they ‘become a real man’ only after they’ve had sex the first time, break girls down into body parts, take revealing clothing as an open invite for sexual interest, go on about how good they are in bed after receiving an initial ‘no’ as if their dick is a product that the girl just doesn’t know she wants yet and the guy didn’t sell it on his first try??? and many more things
@ straight girls, please. please. take your homophobic hypocrisy and realise that girls who like girls are not your enemy.
if we flirt with you, because not all of us have amazing gaydar and sometimes we just gotta try, and you’re not into us?
if you just say so, the most likely scenario is that we will sincerely apologise and then move to the other side of the room or in any other way leave you as well alone as we possibly can.
we are not your enemy.
and we don’t like girls just because you’re girls.
you are not body parts.
you are not a trophy.
we don’t call your outfit cute because we want to get between your legs.
you are not new territory that we want to conquer.
you are not an area on a map that we want to mark with an “x” so we can brag about how we’ve been there.
you are not a pussy that we want to defeat.
the predatory lesbian and the hyper-sexualised bisexual is a myth.
