On Tuesday, December 20, staff and students at Willard Intermediate South school were injured when two dogs identified as a pit bull mix breed made their way into the playground.
That's not a fucking pitbull then IS IT?!
The dogs were euthanized in order to be tested for rabies. The tests will be completed today, and we expect to have results within the next couple of days. During the investigation, it was determined that one of the dogs was not vaccinated and no proof could be provided that the other was up to date on its vaccinations.
So it could've been rabies but you go straight to the bullshit bioessentialism and insinuation that genetics can predispose one to violence.
Obligatory link to my effort post on this phenomenon (reddit link because the OG here is in archive limbo)
Yeah, I'm not suggesting that a small dog can't be just as aggressive as a large dog, but I am suggesting that selective breeding can lead to change in temperament and aggression, this a predisposition towards violence, which you imply isn't true in the body of your post.
I checked out the reddit post and banning pit bulls as a means of soft-redlining makes sense, but I don't think that's super relevant to the selective breeding/instinctual behavior element I'm trying to figure out here. It claim the bans aren't based on statistical evidence, but that's there's no refutation about what evidence that gets presented(there might be in the full text but I don't have access to it).
Also in that post is DNA discourse, which I'm skeptical of—yes, a given dog might have only 40% pit bull DNA, but when it comes to behavioral heritability, as far as I understand, it's not the overall amount of genetic code but whether or not specific markers and all that are present, so if that DNA percentage happened to include the right genes then they get the behavior. I might very well be wrong on that, this is testing my high school biology knowledge so feel free to correct me!
There is no scientific evidence to support this though. There have been attempts to do so but there is no actual scientific study to support this outside of the thousands of years it took to cause dogs to become an entirely separate species from wolves.
Which it should also be noted happened because dogs chose humans as much as humans chose dogs.
If anything they are predisposed toward a communal relationship cross species which resulted in our symbiotic relationship.
This study seems to support breed genetic heritability of behavior, specifically including aggression of various types (owner, dog, stranger). I know there's other studies with different results, but I'm not at the level of literacy on (or, frankly, investment in) the topic to study up on methodology to decide which is more valid.
Species wide, yes, dogs are definitely predisposed to human-based altruism, but that doesn't mean breeds can't have higher levels of aggression than others within the same species.

Here’s a scientific study done in the Soviet Union regarding domesticating foxes. The researchers themselves noted significant behavioral differences. If that’s insufficient data due to bias, the researchers also noted significant hormonal differences (apparently hormones linked to stress response halved?)
yes but can this be attributed to genetics or the fact these animals were raised in captivity? What was the control group here?
The earlier generations here, also raised in captivity and being noted as being less domesticated, should work as a control group here or am I missing something?
I think the biggest question is how much of this behavior is taught (be it by humans or through their parents). E.G. it's already been demonstrated that crows can pass on information about potentially dangerous human individuals.

I'd argue even the tamest foxes from a 1950s estonian fur farm don't exactly have a great trackord towards humans
Hmm, at first glance training/teaching seems possible. After all, the foxes were apparently kept in cages in a barracks like structure - so they should be able to see each other and how other foxes react to humans.
However, this seems like it can’t account for much of it, just given the length of the study and amount of generations. It seems there were behavioral changes between the foxes - generation to generation - and this went on for 40 generations.
How many generations can foxes get the benefit of learning from other generations before we’d expect significantly diminishing returns? 1? 2? Maybe 3?
Meanwhile they have significant changes in their hormones (stress hormone halving every 10 generations, higher levels of serotonin, significantly changed reproductive behavior, significant changes to hormone producing organs) that correlate strongly with the behavioral changes.
It seems a bit silly to me to think that, given this background, a significant amount of the behavior is attributable to inter generational learning.
The page also mentions follow-on studies. Apparently the domesticated foxes had 40 different gene expressions compared to farm raised foxes. Additionally, it seems there was a different experiment ran with rats, in which, starting from the same rat group, they were able to breed hyper aggressive and hyper docile rats in short order, which apparently resulted in genetic differences between the two groups.
