Domestication of dogs is said to be around 15,000 years ago and “caveman” refers to humans in the paleolithic which is between 3.3 million and 11,700 years ago. So there’s a few thousand years where technically a “caveman” could have a pet dog.
Domestication of cats occurred around 9,500 years ago so past the cutoff for caveman.
I always see those videos where people give kids a walkman or a rotary phone and ask them to figure out what it is or how it works. I’m imagining some medieval merchant handing me an abacus and laughing because I can’t figure it out.
A lot of hydroelectric dams have visitor centers and I know of at least one cheese factory that has a storefront and walkway where people can see parts of the factory. I’d assume it’s not common for factories though.
I work at a factory and, for insurance purposes, the bosses don’t let anyone on the floor without them watching hours of saftey videos. There also isn’t much to see. The machines are guarded up so much that you can’t even see most moving parts. It’s just magical black box material goes in, product comes out, type of stuff. Some factories also keep their setup and processes a secret.
I honestly just looked up the dates on Wikipedia! I was surprised that the dates of dog domestication and “caveman” actually overlapped but it feels like a technicality to me. The question is definitely subjective. The date range of “caveman” is literally millions of years. Human ancestors 3 million years ago and 11,700 years ago would have huge differences. I’d assume 11,700 years ago the people were more like nomadic tribes and less like “caveman”. I also don’t believe the first dogs were really pets as much as they were just alright with being around humans. Whereas the domestication of cats article talks about finding humans being buried with cats which is more of a direct sign of a pet relationship.
It’s definitely an interesting question that deserves a bit more thought than overlapping dates!
