Its just a case of need, and wanting to.
Intrude: Actually about 85% of things can't, or they would have been. There has
always been a need, and there has
always been a want. You think Africans down in the Serengeti just decided to accept starving for most of history?
Foxes are overall quite similar to wolves and cheetahs in that they're on the edge of the limit. I'm also going to point out that providing one single example and saying it proves
everything else can be domesticated is just about the largest hasty generalization I've ever seen.
You can't domesticate elephants. You can't domesticate zebras. You can't domestic lions. You can't domesticate giraffes, or hippos, or antelope, or most of the megafauna on this planet. People have tried, and it straight up doesn't work. I refer you to the Anna Karenina section of
Guns, Germs, and Steel. I believe people who have you know, actually studied efforts at human domestication of animals through history, might be the ones to consult.
Aha, well I guess that is more down to the life cycle of the Elephant being far to long to domesticate... it takes many generations to reach domestication.. and noones attempted it with an elephant.
You're right. In the
thousands of years that elephants have been used for heavy labor, I'm
sure nobody bothered, figured out it didn't work, and instead undertook the method of capturing and taming them instead, which has been used to this day! Clearly not.
You don't even know enough about this subject to argue it. Why are you bothering?
