Ligers

[Pembroke_Corgi]

Horses, dogs, cats etc were once non domesticated animals, meaning 'wild'

So its ok that humans domesticated these animals over hundreds of years...but humans should not attempt to domesticate any other ones...is that what you mean?

Why is it that big cats or so called 'wild' animals cannot over hundred of years be domesticated? IE Breed to coexist with humans

Well, domestic cats ARE essentially domesticated "big" cats. I think they are mostly closely related to African and European wild cats. And, it does take a lot of generations to make an entirely new species. Just like dogs are closely related to wolves, they are not wolves- they are another species. How many generations of intentional breeding this would need I have no idea.

You could never make a new species with the Liger because they are a crossbreed- and therefore sterile. If they found a way to breed a tiger/lion and the offspring was fertile this might be possible- but it would require some genetic engineering. The definition of a species is a group the can interbreed to produce fertile offspring. Lions and tigers are closely enough related that they can produce offspring, but they are not of the same species so the offspring is sterile. You cannot therefore breed a liger to a liger.

there have been occasional cases of ligers that weren't steral but it's rare. Just like with mules there is a rare non sterile one but then they have to brred to a tiger lion or a horse or mule since you wouldn't be able to find another nonsterile hybrid, most likely.

It only takes about 40yrs of intensive selective breeding to get a domesticated species it takes more if you aren't so strict in your breeding practices

If you hybrid a domestic to a non-domestic it only take a few generations and after a certain number they aren't sterile any more, like with the small cat hybrids but with most of those it's usually just the male that's sterile as they are more closely related. And it's the same case as above they are non-domestic bred to domestic, then hybrid bred to domestic, hybrid to domestic till a generation that leaves them with all the desirable domestic traits but still looking like a non-domestic.

Mules haven't turned into their own species yet since no one has pushed to like they do with the hybrid cats but mules are still hugely popular.

If you think a Hybrid is wrong no matter if it's a hybrid breed dog or a hybrid exotic domestic species then there's nothing I can say but to those more open that might think a mule is okay but a liger isn't then it's worth thinking over a bit more.

oh and meant this to be in the last post but a dog is 100% DNA the same as a wolf a dog and a wolf are essentially different breeds or you could call dogs a subspecies of wolf as sience now classifies them. There's as yet no genetic test to determine a wolf from a dog or hybrid of the two.
