According to Guns, Germs, and Steel, what are the 6 characteristics of domesticated animals ? Guns, Germs and steel

In Chapter
9 of ,discusses the six main characteristics necessary for an animal to be
domesticated successfully.

1. Captive breeding: Some animals breed
   easily in captivity and others do not. For an animal to be domesticated, it must breed easily
   and readily in captivity without the need for artificial aids or inducements. While modern
   technology has contributed to the ability of zoos to breed rare and exotic animals, that
   technology did not exist when animals were first domesticated.
2. Quick
   Growth: To make raising animals for food productive, the animals must grow quickly so that their
   food value is worth the investment in feeding and care.
3. Docility: An
   animal must be fairly docile and easy to handle by humans and also avoid getting in fights with
   other animals to be domesticated easily. Animals which routinely attack their owners and
   herd-mates are hard to care for.
4. Social/herd structure: Animals that have
   social herd structures and shared territories in the wild are easier to manage than solitary
   animals.
5. Flexible and efficient diet: Domestic animals must have a
   flexible and efficient diet on which they can readily grow and thrive. Domestic food animals
   should be basically herbivorous so they can graze rather than requiring special
   diets.
6. Calm: Animals such as antelope which are prone to panic attacks
   escape or injure themselves and so make bad choices for domestication.
