nimal domestication is closely associated with sustainability through its links to plant domestication, food and transport systems, and social organization.
There are 148 mammals in the world weighing over 45 kilos (100 lbs) and around 1900 14 had been domesticated. Seven of these domesticated species were from SW Asia, and of the world’s five most important domesticated animals (sheep, goats, cows, pigs, and horses) only the horse was absent from this region. Five were present in East Asia, one in South America and none in North America, Australia, and sub-Saharan Africa. This is a powerful argument for the influence of resources, especially biological ones (rather than cultural factors), on the emergence of agriculture, there being a strong correlation between the availability of domesticable plants and animals and the dates of origin of agriculture and herding.
