Oh the genetic confirmation for dingoes to have arrived in Australia is about 8000 years ago these days. So it’s about when did the extra muscles evolve and in which genetic lines? Dingoes and the new guinea singing dog are traced to have come from the wolves domesticated in Asia, so I guess they wouldn’t have them unless they evolved independently or the genes spread before they got separated in Guinea and Australia? But then do japanese breeds also not have them since they’re from the same lines probably? I don’t know, there’s just too little information online. Or if there’s more, I can’t find it
Another element that could be at play here:
He thought it was a dog.
Dogs, because we domesticated them, have muscles around their eyes, that allow them to make eye/eyebrow expressions.
Wolves do not have these. Because they’re the ones we did not domesticate for millenia.
So, if he was expecting dog expressions… wolves literally cannot make the same facial expressions.
They essentially always look like they have RBF, in comparison to a dog.
Interestingly some dog breeds also still lack those muscles, like huskies
Huh! You’re right, I did not know that.
Huskies are… much closer to being actual wolves though, genetically speaking.
Seems like this applies to malamutes and samoyeds as well…?
I wonder do dingoes have them. I haven’t been able to find any information on that yet
My, ahem, blind guess would be probably not, as they’ve… not been widely and thoroughly domesticated for 20,000+ years?

No idea what the more precise timeline is, for when and where dogs started having eyebrow muscles.
Maybe if we did something comparable to the Human Genome Project, but for dogs, we could figure it out, lol?
It’s thought the species we domesticated was distinct from wolves of today. That species went extinct in the wild.
