Goat:
Goat, also known as summer sheep and black sheep, is one of the earliest domesticated domestic animals. It is speculated that in the Neolithic Age, more than 10000 years ago, human beings began to domesticate goats. Most scholars believe that goats domesticated in the mountainous areas of western Asia were brought to Africa, Europe and Asia with the migration of nomadic people. There is evidence that China was also one of the first countries to domesticate goats. Due to the limitation of primitive human activities, domestic goats in various places have to be domesticated independently.
