Transcript:
Not all wild animals can become domestic animals. In fact, only fourteen species are fully domestic. According to one scientist, he says that six things must be true before IT can happen.

Secondly, the animal must grow fast, because slow growing animals are unhelpful to humans. It also needs to breed easily. If the animal doesn’t have babies, the species will soon disappear. The animals shouldn’t be frightened when placed in a small space, because this is dangerous to humans. Finally, it helps if the animal lives in a group in its natural environment.
