(Roughly) how long would it take to domesticate an alien beast?
Assume we have modern knowledge and techniques.
Assume the beasts are mammalian and similar biologically to Earth beasts.
As far as this question is concerned, anything that can be kept as a "pet" or used for farming is domesticated.
I am just curious as to how long it would take to change a wild animal into something like a dog, cat, horse, cow, pig or any other domesticated breed of animal.
Would it help if we could take the beast out of its natural habitat, or would this make the process more difficult?
Ive heard that some breeds of dog were wild as little as 300 years ago, but then I know that other breeds have been with us for thousands of years.
