Raccoons are showing early signs of domestication

> Oddly, tameness has also long been associated with traits such as a shorter face, a smaller head, floppy ears and white patches on fur—a pattern that Charles Darwin noted in the 1800s.

Hmm, so evolutionary pressure of existing around humans makes animals cuter.

I wonder why we find these features endearing?

forinti•3d ago
I would bet on Paedomorphism, because we find babies and puppies cute.
zamalek•3d ago
My guess: possibly co-evolution. The article subsequently describes the genetics behind things becoming cute - which would have been completely benign to our ancestors (the core of your question). However, those of our ancestors who completed domestication of these animals (by random chance) would have enjoyed more protection from predators, rodents, etc. Those of our ancestors who attempted to domesticate things without the mutations might have had bad companions at best, and would have been predated at worst. This would have provided evolutionary pressure to adopt animals that were showing early signs of domestication. What we call "cute" is merely "likely to cooperate with us."

Animal Auditions: Cute vs. Food - Denis Leary

https://youtu.be/IZBAtd9rty8

Perhaps a combination of adaptableness, small size, prodigious reproduction, and cuteness saved some species from being wiped out whereas other species didn't fare so well once humans arrived and transformed their territory. Adapt to urban encroachment or face extinction.

> I wonder why we find these features endearing

It's a side effect, evolution made sure we take care of our offspring.

sdwr•2d ago
I believe the main biological lever is retaining juvenile features as adults, physically as well as mentally (like with dogs). What we see as cute is an honest signal that they are more child-like: less aggressive, more trusting and pro-social.
LeifCarrotson•2h ago
I also think that this is the central cause of a wide variety of domestic/cute adaptations. There are too many separate features to believe that raccoons and dogs and cats and a dozen other species all select for these same elements independently.

I no longer have the book on hand, but read a few months ago that this correlation between juvenile traits and domestication was one of the main theses of Barrett's "Supernormal Stimuli" in Chapter 4. She cited a few studies of fox domestication [1], [2] and other works to support these theories.

I thought it's because adrenalin and melatonin are produced in the same brain region, or something like that.
nine_k•1h ago
Since humans associate cuteness with large eyes and small body size, nocturnal / twilight animals, like raccoons, sugar gliders, cats, squirrels, etc have a larger chance to be domesticated as pets.

Daytime, larger animals (e.g. sheep, goats, or even rabbits) have a larger chance to be domesticated as food.

breakpointalpha•21m ago
I've heard that the same process of domestication towards "cuteness" has been outlined in human evolution too.

Larger head-size relative to the body, larger eyes, smaller jaws and noses, longer limbs, etc.

Interesting parallels across species towards less aggression, greater pro-social behavior, more physical traits that shout "trust me, I'm harmless."

Almost like pro-social, intelligent team co-operation is a huge advantage compared to solo predatory behavior.

> “I’d love to take those next steps and see if our trash pandas in our backyard are really friendlier than those out in the countryside,” she says.

Would they have to measure "biological" friendliness, comparing lab raised countryside-descended and city-descended raccoons? Domesticated animals can be very unfriendly. Feral cats for example.

potato3732842•3d ago
It'll be interesting to see what their methodology is. Trapping tends to piss off any raccoon regardless of urban vs rural.
burnt-resistor•3d ago
Foxes too, generally. The average temperament tends to include curiosity, playfulness, and wariness but not moral fear of humans. People keep them as household pets so I'd call that domesticable. An experiment to speed up the process of fox domestication was undertaken. [0] Foxes tend to not be like almost all wolves (and many wolfdogs) which are reserved, not prone to social openness, and hard to read like American Akitas which makes them dangerous by dominance challenging, miscommunication, and untrustworthiness.

Raccoons have been living literally inside of houses for centuries.

One was kept as a pet in Jamestown Virginia in the 1600s. Another lived in the White House in the 1900s. Surely, not a decade has passed between have there been NO domesticated raccoons in the US? If living near humans changes animals, that started at least 25,000 years ago here in North America. Not recently.

My neighbors had a pet raccoon growing up. It lived inside but would come and go.

The people who wrote this article seem out of touch with the topic they chose to pretend to be experts about?

If dogs started out as wolves and ended up as English bulldogs, imagine how stupid raccoons will eventually look.

That's a recessive trait that is fatal if they get two copies of it. When left to their devices they'll return to being normal cats in a few generations.

Most dogs, arguably, too. But there are French bulldogs, dachshunds, and pugs.

Among domestic cats, there are Persian cats and Sphinx cats.

Skunks apparently make great pets (but need to have their stink glands surgically extracted), the pitch is smart like a cat but faithful like dogs
cinntaile•2h ago
I think dogs in general are smarter than cats.
Sohcahtoa82•2h ago
Dogs are certainly better at looking intelligent. I think dogs, being a more social animal, are more eager to please, and so are willing to be trained.

Cats can vary wildly. One of my cats seems dumb as a box of rocks and haven't even grasped the idea of object permanence. If she's tracking a laser, and I move it around a corner, she can't figure out where it went. She goes from intense staring and tracking to standing up and looking around, confused. When I bring the laser back around the corner, she's instantly back to squatting and tracking it.

Removing the scent glands of a skunk is considered about as ethical as declawing a cat. It just isn't really done anymore. Maybe 30 years ago...
cogman10•1h ago
I don't really understand this. Isn't it about as surgically invasive as getting a pet spayed?

Does the scent gland do anything more than just stinking? For a cat, removing the claws literally removes bones from them. It limits their mobility and hurts like hell.

(Not that I want a pet skunk. Just curious as to why it's unethical)

TylerE•1h ago
I mean, you're removing part of a living animal for human convenience. If the ethical issue isn't obvious I don't know what to tell you.

The practice has been banned in the UK for almost 20 years, under the exact same laws as ban declawing cats. It's unnecessary mutilation with no medical justification.

We treat deer for ticks, etc. A decade ago, I think we would have been smart enough to treat wild raccoons for this parasite, but the time of human domestication is over. In another decade, I expect humans will be marking their territories with feces again.

Amusing, albeit mostly irrelevant, sidebar...

On Facebook, there's been this running gag/joke/meme/whatever going for at least the last year, where anytime the official North Carolina Wildlife Resources Commission page posts anything, a large portion of the comments quickly turn into a discussion of the merits (or lack thereof) of pet raccoons[1].

I don't know exactly how it started. Somebody innocently asked "How do I get a permit for a pet raccoon?" and the page replied "You can't, they are illegal in NC" or something prosaic like that I imagine. But it became a big "thing" and now raccoon talk is everywhere. The page controllers play along with it, which is part of why it's kept going so long I guess. But sometimes they'll get semi-serious and post something like

"Look, all joking aside, the reason pet raccoons are not allowed is because no matter how friendly raccoons look, they are wild animals, not domesticated, and they can be a hazard to you, and your family and <blah, etc, etc>".

Soooo... I'm just waiting to see somebody post this very article in a comment on that page with a note saying "Suck it, NCWRC!" (all in a spirit of good fun, of course).

[1]: or one or more of another of a small set of topics, including flounder, pet alligators, armadillos, UFO's, and the possibility that the person running the page is the product of secret government genetic engineering experiments involving "all of the above". It's... complicated.

EDIT:

Welp ,that took about as long as I expected. ROFL.

Would be cool if it eventually leads to a Cambrian explosion of raccoon varieties after generations of breeding desirable traits.

Just remember to remain wary of the cute ones.

> Raccoons are a rabies reservoir in the eastern United States, extending from Canada to Florida and as far west as the Appalachian Mountain range. Within these areas, 10% of raccoons that expose people or pets have rabies, making them one of the highest rabies-risks in the United States.

> 10% of raccoons that expose people or pets have rabies

I don't understand the language of this quote. What does it mean for an animal to expose people?

kotaKat•1h ago
An “exposure” in this instance to rabies would be physical contact - a bite, scratch, or from its saliva on an open wound for instance.
