1. Introduction
The Neolithic revolution, which began some 12,000
years ago in Turkey and in other parts of
the Fertile Crescent, caused man to adopt a sedentary lifestyle, which on its turn speeded up
the process of domestication of animals. Th
e dog was already domesticated before this
revolution and had served man as help in hunt
ing. During hunting, man probably figured
out that a few of the hunted species could be tamed easily, so subsequently other species
such as the chicken, the duck,
the goose, the sheep, the goat,
the cow, the pig and the camel
were domesticated. This implicated for these an
imals a life closely to their masters, many of
them in stalls or in corrals. In ancient farm types, man and anim
als shared the same
airspace, especially during winter. Alternativel
y, in some regions herd animals guided by
shepherds were still allowed to be in the fields in relative freedom, some of them, however,
only for a part of the year.
