HORTICULTURE

Detailed explanation-1: -Cattle, sheep, and goats were first domesticated in West Asia, but the history of utilization of these livestock in China is controversial. The Hexi Corridor, located in the northwestern Gansu-Qinghai (GQ) region of northwest China, was a conduit of cultural exchange between East and West Eurasia.

Detailed explanation-2: -Archaeological data suggests that there two distinct places where goats were domesticated: the Euphrates river valley at Nevali Çori, Turkey and the Zagros Mountains of Iran at Ganj Dareh. Another possible domestication site is the Indus Basin in Pakistan.

Detailed explanation-3: -Sheep were among the first animals to be domesticated by humans (although the domestication of dogs may be over 20, 000 years earlier); the domestication date is estimated to fall between 11, 000 and 8, 000 BC in Mesopotamia.
