I am thinking Jared Diamonds assertion here was oversimplistic. "If it can be domesticated, it has been"
Umbral,
Oversimplistic? First, his comments regarding domestication are not simply "If can be domesticated, it has has been domesticated". Second, Diamond is a trained scientist, something you are not.
Leaving asides the fact that animals such as the fox is domesticable, but hasn't been. I think it is more of a question of an effort/reward ratio for a tribe or civilization.
Looking at the effort and reward curves intersect is a beginning and, oddly enough, something Diamond addresses.
If you can breed it in captivity, practically any species is domesticable.
Nonsense. Domesticability is much more than breeding in captivity.
But with many species, you'd have to spend so many generations of breeding to socialize and pacify it, that you might as well not bother.
First, some species can never socialized or pacified. Second, as you correctly point out, the effort required to domesticate others is too great.
Or the Fox. You need to breed it for sociability, since foxes are not pack animals, but as the russians have shown, they are easily domesticable.
Easily domesticated? Score a laugh point.
A forty-plus year effort undertaken in a scientific research lab and funded by a superpower which produced less than 100 individuals and a few pets does not point to "easy" domestication. And a domestication effort that is essentially over too.
The Russian scientists involved are looking for funding, hence the few pet sales, and, if they don't receive it, those domesticated foxes will either die out or be subsumed into the wild population, something we don't see with dogs or cat. Feral dogs and cats can be captured and re-socialized with relatively little effort. The same can't be said for the project's foxes.
What always gets lost in these discussions is that any domestication effort needs to take place within a Stone Age level of technology. You need to domesticate your targets early lest the niche they're meant to fill has already been filled by another candidate.
The female is probably quite domesticable...
Lions? Half-ton carnivores? Those lions? This isn't the ASB Forum, you know.
Best bet to domesticate something unusual is a civilization which uses the animals for some religous purpose and keeps a breeding pool for it. If it is stable over a long time, the animal keepers might consider it in their interst to breed them for "not-killing-us"
Those religious animals bred in captivity would be no more "domesticated" than the centuries of bears raised in captivity for European blood sports.
You, and most of the others in this thread, really need to review just what domestication actually means.
